At present, Dongfeng Nissan has not launched a sales strategy about Xuanyi Pure Electric. During the visit, some 4S stores in Guangzhou and Shijiazhuang did not have existing cars, and a 4S store in Beijing stopped selling until further notice.

Full text summary：

　　The landing of the New Deal in 2019 has brought new energy vehicles into the era of low subsidies. Many people predict that new vehicles will usher in a wave of price increases. However, through our visit, we found that the prices of new energy vehicles have not changed significantly, but the preferential margins of models in some regions have shrunk to varying degrees. Although Changan Automobile, BYD, and Great Wall Motor’s Euler brand have issued insurance plans, the time span is not long; Chery Automobile raises the guide price by releasing new year models. This "price increase" method is more clever and easier for consumers to accept.

　　It has been more than a week since the New Deal was launched, and most new energy vehicle companies have not announced their new sales strategies. After all, not every company wants to pay for the subsidy. What are these car companies waiting for? It may be the competitor’s action, and the latecomers can better find the balance between sales and profits. In the cold winter of the automobile market and the transition period of new energy vehicles to marketization, price increases are no different from risks! Next, we will continue to investigate the terminal sales of some popular new energy vehicles and the implementation of official price protection measures, so stay tuned.

　　Invoice is no stranger to everyone. Going out to take a taxi, checking out the hotel, watching a performance, etc. may all be invoiced. For enterprises, invoices record the detailed information such as the name, quantity and amount of goods and services traded, and reflect the production and operation of enterprises. The invoice information of thousands of households and thousands of factories and stores comes together, which constitutes a "treasure house" of tax big data. How is tax big data collected and analyzed? What changes can we see in economic development through tax big data? Recently, the reporter went to State Taxation Administration of The People’s Republic of China for an interview.

　　Tax big data has the characteristics of covering all economic fields, reflecting economic activities quickly, fine data granularity and accurate recording of economic activities.

　　One day in May, Guangzhou Xiangcrocodile King Industrial Co., Ltd. sold 567 pairs of leather shoes. After receiving the outbound list from the warehouse, Chen Qunyi, the company’s financial officer, immediately logged into the "VAT invoice tax-controlled invoicing software" system, and entered the information of the buyer "Dalian Hongen Zhijie Trading Co., Ltd.", the quantity "567 pairs" and the total price and tax "101,546 yuan", and then recorded the buyer information and commodity information. Then, Chen Qunyi printed the invoice, stamped it with the special invoice seal, and sent this special VAT invoice to the buyer.

　　When the enterprise issues invoices and enters the above transaction information, the tax department also collects the valuable data reflected by the invoice related information.

　　"Taking VAT invoices as an example, the data collection process includes three links: data entry, data concentration and data processing." Li Zhi, deputy director of State Taxation Administration of The People’s Republic of China Tax Big Data and Risk Management Bureau, said that data entry means that the drawer enters the buyer’s name, buyer’s identification number, unit price, quantity and other information through tax control equipment; Data concentration, that is, every invoice issued by the taxpayer and every data item entered will be transmitted to the provincial tax authorities where the enterprise is located in real time; Data processing means to comprehensively integrate, correlate and process invoice data and other tax-related data to provide tax big data support for local tax authorities.

　　On the big screen of an office in State Taxation Administration of The People’s Republic of China, the reporter saw the real-time billing situation of the day, the billing changes in different industries and regions, and so on.

　　"Tax big data includes enterprises, individuals and other economic activities, reflecting economic activities such as investment, consumption, import and export, covering the whole life cycle of market entities from establishment to cancellation, including industries, regions, economic types, scale and other dimensions." Zhao Lianwei, deputy director of State Taxation Administration of The People’s Republic of China Revenue Planning and Accounting Department, said.

　　The VAT invoice records every transaction of the enterprise, and the tax declaration data records every income of the individual … … "Tax big data records the production and operation status of every taxpayer in detail, and the VAT invoice data records every tax-related transaction behavior of taxpayers in detail. In general, tax big data not only covers the whole economic field and reflects economic activities quickly, but also has the characteristics of fine data granularity (that is, high data refinement and comprehensive degree) and accurate recording of economic activities. " Zhao Lianwei said that these valuable data can provide better services and support for macroeconomic decision-making while helping to do a good job in tax collection and optimization of tax and fee services.

　　Of course, the collected data are only "raw materials", and they need to be further "processed" to give full play to their role.

　　First of all, the data should be standardized, that is, the wrong or incomplete data should be eliminated to ensure the integrity, timeliness, accuracy and consistency of the incoming data. On this basis, the data are correlated to connect systems and data items. For example, if the invoice data issued by enterprises are correlated with the value-added tax, enterprise income tax and export tax rebate data regularly declared by enterprises, the consistency or mistakes of the data can be found.

　　"It’s not enough to associate data only. In order to improve the efficiency of data use, we have to label different data. For example, whether it is a general taxpayer or a high-tech enterprise. Through data standardization, data correlation and data labeling, we can integrate the information of the same taxpayer and payer, and support the analysis and application of big data in a wider range and more dimensions. " Li Zhi said.

　　Excavate the economic laws and characteristics reflected by tax big data to create authoritative and reliable economic analysis products.

　　After in-depth "processing" of tax data, it can be used for induction and analysis to form valuable information to help people better judge the economic situation.

　　For example, at present, enterprises in China have invested heavily in innovation, and their innovation engines are full of power, which is fully confirmed in the tax big data.

　　"Now, we choose the indicators related to the high-tech industry labels, extract the data in April, and we can form a data set, and then compare it with the data in previous years, and we will find the changes this year." While operating, Li Zhi pointed to the newly generated data interface on the computer screen and said, "You see, in April this year, the sales revenue of high-tech industries increased by 19.3% year-on-year, with an average growth of 18.9% in two years. From January to April, the purchase of scientific research equipment such as photoelectric instruments by enterprises increased by 45.8% year-on-year, with an average increase of 23% in two years. Among them, the purchase of integrated circuit testing instruments, communication measuring instruments and optical testing instruments and equipment increased by 41%, 33% and 23.1% respectively in two years & hellip; …”

　　For another example, the consumption of domestic residents has gradually picked up and the consumption structure has been continuously optimized, which can also be seen in the tax big data.

　　"It can be seen from the tax big data that the basic consumer market has recovered steadily, the upgraded consumption has grown rapidly, and online consumption has remained vigorous." Zhao Lianwei said, for example, in April, the retail sales of daily necessities such as food, beverage and clothing increased by 43.6% and 35.9% respectively, the retail sales of watches, health care medical equipment, photographic equipment and nutrition and health products increased by 77%, 64.6%, 56.5% and 54% respectively, and the sales revenue of Internet information services and Internet retail increased by 42.5% and 32.9% respectively.

　　Tax big data can also assist relevant departments to analyze macroeconomic operations and better carry out management and services.

　　In recent years, the tax authorities have continuously explored the economic laws and characteristics reflected by tax big data, actively created authoritative and reliable economic analysis products, and focused on strengthening conventional tax analysis, implementing major national development strategy analysis, doing fine hot topic analysis, and doing excellent policy effect analysis. "For example, we closely follow the emerging and trending problems in the current economic operation, deeply analyze the causes of the problems, and put forward countermeasures and suggestions. For another example, we will scientifically count the implementation of preferential tax and fee policies, carry out effect analysis, objectively reflect the problems existing in the implementation of policies, and timely put forward opinions and suggestions on improving policies. " Zhao Lianwei said.

　　Zhao Lianwei said that the tax authorities also insisted on consolidating the foundation of statistical standards, and standardized the tax statistical standards and caliber to achieve effective convergence between tax statistical standards and national statistical standards, ensuring that the analysis "speaks Mandarin" rather than "speaks dialects". By studying the change of historical data and its matching relationship with economic operation data, we can find out the law of tax data, establish the corresponding relationship between tax data and economic indicators, and ensure the internal logic of analysis is accurate. In addition, by using scientific data analysis methods, the combination of qualitative and quantitative, macro and micro is realized to ensure the objective and scientific analysis results.

　　With the help of tax big data, the supply chain of the industrial chain will be smoother, the policy implementation will be more accurate, and the tax and fee services will be more convenient.

　　"You can complete the tax calculation on the mobile phone, and the information is automatically substituted. It only takes a few hands to give directions and it will be done in a few minutes. It is really convenient!" Hou Ning, an employee of Henan Wenzhiguan Construction Engineering Co., Ltd. said.

　　The tax APP is so convenient and efficient to use, and it is inseparable from the support of tax big data. "In the annual settlement, relying on the information system and strong data processing ability, the tax department provides the pre-filling service of the declaration form, that is, after the taxpayer logs in the APP to confirm his identity, the relevant information is automatically generated and filled in, and the taxpayer clicks ‘ Confirm ’ On the line, the efficiency of settlement has been greatly improved, which has strongly supported the successful implementation of individual tax reform. " Li Zhi said.

　　Tax big data has a great role in optimizing tax and fee services — —

　　To "match the bridge" for enterprises and make the supply chain of the industrial chain smoother. Tax authorities use big tax data such as VAT invoices to carry out multi-dimensional analysis of enterprises’ resumption of work, production and sales, and develop special service platforms, and use tax data to bridge the gap between enterprises, guide the connection between upstream and downstream, production, supply and marketing, and promote the smooth circulation of the supply chain in the industrial chain. Last year, the tax authorities used tax big data to help Hubei enterprises connect with enterprises in other regions, effectively helping Hubei enterprises to resume work and production.

　　Draw a "guidance map" to help make policy implementation more accurate. In the implementation of preferential tax and fee policies, the tax authorities rely on tax big data to accurately screen eligible taxpayers, take the initiative to publicize and coach, and track and monitor in real time to ensure that the policy dividends reach the market players as quickly and accurately as possible.

　　Set up a tax "highway" to make tax and fee services more convenient. The tax authorities have vigorously promoted non-contact tax payment, and realized the policy of "knowing on the code", consulting "answering online", business "doing online" and operation "feasible on the palm". 214 tax payment items and more than 90% corporate taxpayers’ business can be handled online, of which the online tax declaration rate is over 99%.

　　In March this year, the Opinions on Further Deepening the Reform of Tax Collection and Management issued by the Central Office and the State Council clearly stated that efforts should be made to build a smart tax with high integration function, high safety performance and high application efficiency, with the service of taxpayers as the center, the electronic invoice reform as the breakthrough and the tax big data as the driving force.

　　Li Zhi said that the tax authorities will continue to promote the system optimization of law enforcement, service and supervision, realize the integration, integration and upgrading of business processes, institutional norms, information technology, data elements and post responsibility system, achieve a major breakthrough in tax reform and innovation from gradual to systematic integration, and fully help China’s "digital government" construction. In the next step, we will continue to promote three major changes in technology, business and organization, and build four new systems around precise law enforcement, precise service, precise supervision and sincere co-governance, giving full play to the basic, pillar and supportive role of taxation in national governance, and providing strong support for promoting high-quality development.

Within the budget of 150,000 yuan, Geely Xingyue L Zhiqing has rapidly become the new favorite of the family SUV market with its excellent comprehensive strength, and has become a high-profile online celebrity model. If we know its excellent performance and high cost performance earlier, it will become the focus of market recommendation. Now, let’s explore this amazing and well-deserved high-quality car together and unveil its mystery as a treasure-class product.

As another masterpiece of Geely automobile family, Xingyue L Zhiqing’s design deeply integrates the brand’s iconic straight waterfall net, with strong lines and strong business and sports atmosphere. The body is outlined with double waistlines, supplemented by exquisite chrome decoration, which gives the vehicle a sense of visual hierarchy and strength. The front face design is full and full of tension, and the clever use of chrome-plated elements further enhances the overall visual impact. The side contour is smooth, and the multi-spoke sports hub not only enhances the sports attributes of the vehicle, but also creates a stable and fashionable atmosphere. In the rear part, the penetrating taillights are simple and exquisite in design, which effectively improves the recognition and safety of driving at night.

On the power core, Xingyue L Zhiqing is equipped with an efficient 1.5T four-cylinder hybrid engine, matched with the advanced 3-speed DHTPro gearbox, and achieved excellent performance of fuel consumption as low as 4.0L/100km per 100 km, which is particularly prominent in the same class. It is particularly worth mentioning that its engine thermal efficiency is as high as 44.26%, which shows Geely’s profound accumulation and innovation strength in the field of energy saving and emission reduction technology.

Stepping into the car, the interior design of Xingyue L Zhiqing is also eye-catching. Three 12.3-inch high-definition large screens are patchwork, with Galaxy OS intelligent car system and Qualcomm Snapdragon 8155 chip, which brings users a silky operation experience and rich entertainment information enjoyment. The seat not only provides comfortable configurations such as ventilation, heating and memory functions, but also ensures sufficient seating space, so that even tall passengers can enjoy a spacious and comfortable ride. However, it is a pity that the co-pilot seat is not equipped with ventilation function, which may have a certain impact on the comfort of passengers in hot summer days.

In terms of endurance and fuel consumption, with its powerful battery pack and hybrid system, Xingyue L Zhiqing has achieved excellent performance with a comprehensive cruising range of up to 1300km, providing a solid guarantee for long-distance travel. At the same time, the fuel consumption level as low as 4.0L/100km also greatly reduces the cost of users’ cars, showing its excellent fuel economy.

In terms of intelligent technology, Xingyue L Zhiqing also performed well. Galaxy OS intelligent car system is not only rich in functions and convenient to operate, but also brings unprecedented intelligent car experience to users. However, it also brings some security risks, that is, drivers may be distracted by relying too much on screen operation during driving. Therefore, while enjoying the convenience brought by intelligent technology, we also need to pay attention to driving safety at all times.

Finally, although Xingyue L Zhiqing has excellent performance in charging and power consumption, due to its hybrid status, it has failed to enjoy the unique policy preferences of pure new energy vehicles, such as green license, which may become a factor for some potential consumers to consider. However, with its high cost performance, excellent fuel economy and comfortable driving experience, Xingyue L Zhiqing still occupies a place in the domestic medium-sized SUV market and has become the focus of many consumers. And this year’s new models are here, and 25 models of Xingyue have arrived at the store now. Go and test drive!

In 2024, there were many models called "7", but none of them could really carry the banner of smart cars. However, recently, a domestic "Seven Series" appeared, which showed us that "this is the ceiling of intelligent driving and voice control".

As a human being born in the last century, although he grew up with technology, he is not used to voice control, whether it is a car or a mobile phone. When we spit out how anti-human it is to cancel the physical buttons, we actually spit out the mental retardation of the intelligent car system.

Because there are only two results of using voice control, either it looks very retarded or I look very retarded, so in the era when cars at any price have voice control, almost no one can really use it without causing trouble to themselves.

Finally, a car company solved this random problem, not HarmonyOS Zhixing, but Geely and Baidu cooperated. In addition to the big model of intelligent driving, what impressed me the most was the revolutionary changes in its phonetic system. Voice not only partitions, but also cooperates with eye following, which perfectly supports fuzzy voice control.

Thanks to the support of AI technology, voice control is not retarded, and the communication between people and cars is more direct and more like the communication between people. It is also set that when someone is in the car, someone outside the car gives an instruction and does not accept it. This function is quite life-saving.

Another highlight is that it turns the hidden door handle into an invisible door handle, which will not freeze the door handle even in winter. And there is a standby power supply and mechanical switch on each door to prevent the door from crashing and being unable to open without electricity. Millimeter-wave radar is installed in every door, which can keep away from the risk of luxury cars hitting porcelain when the door is opened by voice, and it can be regarded as home.

Although screen shifting is not unusual, it is similar to Tesla model3, but the difference is that in order to prevent the uncertain danger caused by the big screen crash, Extreme Yue 07 has a set of backup electronic shifting mechanisms on the central control platform, which is quite thoughtful.

In fact, the hardware configuration of this car is not unique, and what is refreshing is the details. For example, when it is in the automatic driving stage, blue lights will light up around the car body to remind passers-by and passing vehicles not to be as knowledgeable as automatic driving. This function is very important and not difficult to realize, but no car company has done this in the past. That’s the detail.

At present, most details of Extreme Yue 07 have not been announced, including the battery life and pre-sale range, but from these details, it has defeated all smart electric vehicles before SU7 and SU7.

But I don’t think its competitors are necessarily. Because su7 takes the performance online celebrity route, although the drag coefficient of Extreme Crossing 07 is only 0.198, its selling point is not the new energy acceleration, but the revolutionary upgrade of intelligent driving. The real influence of the opponent is the upcoming listing of HarmonyOS Zhixing’s Enjoy World.

Don’t look at the administrative business route, the body is more atmospheric and more stable. However, as a product endorsed by HarmonyOS, if the product fails to reach the level of’ 07′ in terms of intelligence after listing, I am afraid it will completely lose its civilian market.

This is not a gimmick problem, but a problem of grasping the details of the intelligent driving system. Come on, HarmonyOS Zhixing. At present, apart from slogans, most of us can’t feel what you are far ahead of.

In today’s new car market, independent brands occupy the commanding heights, no matter the quantity or volume of new cars released.

According to the latest data of the Passenger Car Association, in April, the retail sales volume of the national passenger car market was 1.532 million, down 5.7% year-on-year.However, among them, the retail sales of independent brands reached 882,000 vehicles, up 12% year-on-year, accounting for 57.4% of the total market share.

butHelping independent brandsWhat is taking off against the trend is, of course, new energy vehicles..fourmoonNew energy vehicleRetail sales reached 674,000 vehicles, a year-on-year increase of 28.3%.;wholesale78.50,000Cars, an increase of 30..0%.amongIndependent brandRetail share of new energy vehicles64%,Joint venture brandnewEnergy vehicleshareforeheadhave only4.3%, differenceThe magnitude is obvious..

[business card]

"Jinghua" shield machine, with a diameter of 16.07 meters, a length of 150 meters and a weight of 4,300 tons. Lying horizontally, it is even higher than five stories … It looks heavy, but it has high skills: it is a good hand at digging holes and a sharp weapon for tunnel construction, like an underground dragon, such as a "steel pangolin". The shield machine developed by Tiejian Heavy Industry, from running to leading technically, has become another "Made in China" business card after "China High Speed Rail".

Hunan Daily All-Media Reporter Cao Xian Correspondent Hu Qing

In Tongzhou District, Beijing, the west tunnel of the East Sixth Ring Road reconstruction project is under construction. On the ground, beijing-harbin railway got on the high-speed train and galloped by, but the passengers didn’t notice that a "steel behemoth" was steadily driving tens of meters underground.

On April 12, 2022, China’s largest diameter shield machine "Jinghua" successfully crossed the Jingha high-speed railway line. This behemoth plunges underground, causing no disturbance to the ground buildings, and controlling the surface settlement in millimeter level, creating a miracle of the construction of super-large diameter shield machines in China.

This "Jinghua" shield machine rolled off the production line in Changsha No.1 Industrial Park of China Railway Construction Heavy Industry Group Co., Ltd. on September 27th, 2020. Shield machine is known as "the king of construction machinery". China was once a zero foundation, and its technology and market were controlled by people. Nowadays, the domestic brand shield machine represented by China Railway Construction Heavy Industry has occupied two-thirds of the global market share.

Over the past 10 years, how did China shield machine strike back brilliantly?

1 "2 mm" see skill-

Buried in stealth, amazing years

Shield tunneling relies on many cutter heads embedded in the front circular cutter head. The cutter head rotates slowly, like a big mouth, and the cutter head is like a tooth, which "chews up" rocks and sand and transports them through the pipeline.

Shield construction is to dig tunnels under the ground, and there is no need to "open the belly" on the ground, which has little impact on road traffic. In the underground reconstruction part of Beijing East Sixth Ring Road Reconstruction Project, the tunnel shield construction section is about 7.4 kilometers long, and the excavation section size is six times that of the general subway tunnel.

"It is the first time in the world for a shield machine with such a large diameter to dig such a long distance at a time." Railway Construction Heavy Industry undertook the task of developing "Jinghua", and the R&D team faced unprecedented challenges.

The underground space environment is complex, and more than 50 risk sources are densely distributed on the ground. Super-large diameter, super-long distance, super-deep soil cover and super-sensitive environment, some authoritative people in the industry are worried: "Will domestic equipment work?"

Without two brushes, I can’t do it.

In the process of tunneling, the shield machine faces all kinds of interference caused by earth pressure, underground water pressure, mud in and out, and rocks in the way. The R&D team adopted a high-precision gas-liquid balance control technology, and an air cushion cabin was set behind the cutter head cabin, so that the pressure was indirectly transmitted instead of directly impacted. Figuratively speaking, it is the increase of pressure and exhaust; Sudden pressure drop, replenishing qi, and instantly eliminating pressure fluctuation.

"The underground’ movement’ is big, and what to do on the ground is not affected." Zhang Shuaikun, vice president of Railway Construction Heavy Industry Roadheader Research and Design Institute, said that during the excavation of Jinghua, the surface settlement was always controlled within 2 mm.

By June 1, the "Jinghua" had broken through 3,668 meters, and the excavation was more than half successful. In the meantime, a new record of 542 meters in a single month was created. "Whether it is size or technology application,’ Jinghua’ has reached the world’s leading level." Zhang Shuaikun said proudly.

On the network platform, the short video about "shield machine" has been viewed by millions of people. While enjoying the convenience of cars and subways passing through tunnels, people want to know why tunnels are dug quickly and well now.

In the 1950s, China put forward the plan to build a subway in Beijing first. The first phase of the 23.6-kilometer-long Beijing subway project took more than 10 years from construction to trial operation.

Before tunnel construction in our country, the traditional manual drilling and blasting method was used to drill, shoot and dig stone slag, which cost a lot of manpower, material resources and even life. "Compared with the current shield machine that digs hundreds of meters every month, at that time, it was greedy every day, and it could not dig dozens of meters in one month." He Qiping, the 58-year-old chief technology officer of China Railway Construction Heavy Industry, has worked as a tunnel for most of his life and experienced great changes in the industry. He said with deep feeling that it would take at least 100 years to build all subway lines in China at the same speed as that of Beijing Line 1. Because China has its own shield machine, the speed of subway construction has been accelerated for more than 60 years.

Compared with the predecessors in the industry, Zhang Shuaikun, born in 1980s, is lucky. His WeChat avatar is "Jinghua", and the blank space of the photo reads: Burying your head and sneaking, amazing years. These eight words have become the best annotation of the largest diameter shield machine made in China, and also a vivid portrayal of countless hard-working scientific researchers and industrial workers.

2 From "1" to "1000+"-

The "printing machine" of foreigners has become the "competitive machine" of China people.

Seen from the satellite perspective, the super factory of Tiejian Heavy Industry in Changsha, Hunan Province is a shining new industrial landmark.

Ten years before the birth of "Jinghua", Railway Construction Heavy Industry produced the first EPB shield machine named "Pioneer 19".

"Pioneer" broke the game in one fell swoop. "Let the’ foreign shield’ with an average selling price of about 150 million yuan quickly reduce its price by 30% in China." Liu Feixiang, Party Secretary and Chairman of Tiejian Heavy Industry, said.

In the 1990s, China imported shield machines from abroad for the construction of large-scale tunnel projects. Wu Min, vice president of Railway Construction Heavy Industry Roadheader Research and Design Institute, used to drive foreign equipment in tunnel construction units, and he often wondered "when can the domestic shield machine be used".

Foreign shield machines are expensive to sell and the service is more expensive. Foreign companies hold key technologies in their hands, charge high service fees, wait until working days to solve problems, and often refuse to accept the rectification and optimization suggestions of domestic contractors.

The rapid development of China is changing with each passing day. The high-speed rail and subway network are accessible, and water conservancy and mine construction are speeding up. Large-scale engineering equipment like shield machine is too important.

You can’t always be led by foreigners. In 2008, Tiejian Heavy Industry decided to specialize in customized underground engineering equipment.

Supported by the "863" project of the Ministry of Science and Technology, in 2012, China Railway Construction Heavy Industry launched an attack on the first domestic rock tunnel boring machine (TBM). Different from the shield machine that eats soft rock and gravel, the rock tunnel boring machine takes hard rock as the "next meal", which is also the weak link of the autonomy and localization of tunnel boring equipment in China.

Knowing this news, Wu Min gave up his job with higher income at that time and devoted himself to the development of the first domestic TBM.

From scratch, grope forward. For twenty or thirty big parts such as cutterhead, shield, main beam support and propulsion, a research team is set up for each part. Every data is accounted for over and over again, and it is pushed over and over again. More than 3,000 mechanical drawings have been audited.

At the end of 2014, the first domestic open TBM was rolled off the assembly line of China Railway Construction Heavy Industry. In participating in the construction of water supply project of Jilin Province, the highest monthly footage of this TBM reached 1,209.8 meters, and the bid was completed more than one year ahead of schedule, leaving the foreign brands that competed in the same field and ranked first in the world at that time far behind. "Very uplifting!" Wu Min is quite proud of this product.

Today, there are 40 shield machine production lines in Changsha No.1 and No.2 Industrial Parks of Railway Construction Heavy Industry, which has become the largest underground engineering equipment manufacturing base in the world. Over the past 10 years, more than 1,000 roadheader machines have been sent from here. The shield machine, once regarded as a "printing machine" by foreigners, has now become a "competitive machine" for China people.

Great country heavy weapon serves great country project. The western water conservancy project, with a maximum buried depth of 2268 meters, is all over the altered rock belt. The variable diameter open TBM solves the "stuck machine" problem that plagues the world excavation industry and successfully breaks through the barrier. In the Pearl River Mouth Tunnel of Shenjiang Railway, "Shenjiang No.1" advanced to the depth of 106 meters, helping to build a half-hour living circle in Guangdong-Hong Kong-Macao Greater Bay Area …

3 From "Apprentice" to "Teacher"-

China equipment accelerates the equipment world.

In the early summer, on the west bank of Xiangjiang River in Changsha City, the super-large diameter shield machine "Xingsheng" is being debugged, and the trip across Xiangjiang River will be started soon, which will help alleviate the traffic bottleneck in the central city of Changsha.

From Beijing to Changsha, Railway Construction Heavy Industry has developed 6 sets of shield machines with super-large diameter of 15 meters and above. The core technology of shield machine in China has become more and more mature and powerful.

Shield machine integrates advanced technology in many fields, such as machinery, electricity, liquid, light, control, engineering, etc. Its manufacturing process is complex, and its degree of autonomy directly reflects the industrial level and industrial chain perfection of a country.

Size, there are "super" and "tiny". A shield machine with a diameter of only 0.5 meters, "the sparrow is small and complete."

Technology, from running to part leading. Horizontal excavation, vertical shaft, inclined shaft, various modes and special-shaped sections are not a problem.

Market share from supporting role to leading role. The output of rock tunnel boring machine of China Railway Construction Heavy Industry has been the first in China for five consecutive years. The domestic brand shield machine represented by China Railway Construction Heavy Industry has climbed to more than 95% in the domestic market share, accounting for two-thirds of the global market share.

People have no me, people have my advantages, and China roadheader strode out of the country.

In 1950s, Soviet experts came to China to help Beijing plan the first subway line. Sixty years later, five shield machines from China Railway Construction Heavy Industry participated in the construction of the southwest section of the third interchange ring road of Moscow Metro, and were affectionately called "five golden flowers" by the locals.

The "Five Golden Flowers" proudly bloomed in snow, which overcame the extremely cold environment of minus 30 degrees Celsius, set a new record for local subway construction and became a model for overseas construction of shield machines in China.

On the eve of the Spring Festival in 2022, after more than seven hours of overseas connection, Railway Construction Heavy Industry finalized cooperation with an Italian construction company. China shield machine is about to enter the Italian market for the first time.

"Hundreds of technical parameters are compared one by one, and the attitude of the other party gradually changes from distrust to trust." Zhong Qing, an engineer from the Research and Design Institute of Railway Construction Heavy Industry Roadheader, said that China shield machine has comprehensive advantages in terms of price, performance, quality and service, and is more competitive than foreign brands. He said with emotion, "I used to be a teacher, but now I am a teacher." In less than 20 years, the change is too great. "

The reporter walked into the assembly workshop of Railway Construction Heavy Industry, but saw a shield machine being hoisted and tested in an orderly manner. The base label showed that the destination was Sri Lanka, India and Singapore. In the first quarter of this year, the amount of new overseas contracts signed by Railway Construction Heavy Industry increased by 9 times year-on-year.

Along the "Belt and Road", China equipment accelerates the equipment world. In 2021, Tiejian Heavy Industry ranked among the top 30 global construction machinery manufacturers and ranked first among the top 5 global full-face tunnel boring machine manufacturers.

Move the classroom into the workshop

I have a "billion-point" heart.

Deng Kangwei (a junior majoring in urban underground space engineering in Central South University)

It is accidental to choose the major of urban underground space engineering. On the weekend of my freshman year, I read several books related to urban underground space in the library and learned that the use of above-ground space is becoming increasingly saturated, and underground space will become the "main battlefield" for urban construction. So, when I subdivided my major, I chose this major.

This semester’s professional courses often talk about shield machines. As a young observer of Hunan Daily, I came to Tiejian Heavy Industry to observe the shield machine at close range. For me, it is like moving the classroom into the workshop and learning the principle and structure of the shield machine in front of books and drawings in class. It is a completely different experience.

It took me six hours to assemble the toy of shield machine building blocks presented by the enterprise, so I can experience the fun of "manufacturing" a shield machine. In fact, there are more than 30,000 large and small parts on a shield machine. From conventional diameter to the development of super-large diameter shield machine, technicians have devoted themselves to tackling more than 2900 days and nights.

I was deeply impressed by this statement that the shield machine has changed from a "printing machine" for foreigners to a "competitive machine" for China people. Scientific researchers have gnawed at the "hard bones" of core technologies, and industrial workers have developed the hard skills of striving for perfection, so that China’s independent research and development of shield machines is no longer subject to people, from zero foundation to mastering key core technologies, leading the world.

Walking into the super factory of shield machine, I saw the big scene of shield construction and became a "shield driver" as I wished. This "immersive experience class" made me feel the innovative power of hard-core technology, which made me feel "a little bit" and made a different plan for the future.

Urban underground space contains unlimited development space, and the future awaits us to change and create with broader knowledge and broader horizons.
