When presiding over the symposium on promoting the comprehensive revitalization of Northeast China in the new era, General Secretary of Supreme Leader stressed: "Actively cultivate strategic emerging industries such as new energy, new materials, advanced manufacturing and electronic information, actively cultivate future industries, accelerate the formation of new quality productivity, and enhance new development momentum." Industry is the foundation of development, and it is necessary to build a modern industrial system to accelerate the formation of new productive forces. Report to the 20th CPC National Congress of the Communist Party of China made a strategic plan for "building a modern industrial system", and the first meeting of the 20th Central Financial and Economic Committee proposed "promoting industrial intelligence, greening and integration, and building a modern industrial system with integrity, advancement and safety". This provides scientific guidance for us to build a modern industrial system.

　　Seize the opportunity of the new round of scientific and technological revolution and industrial transformation to promote the development of industrial intelligence

　　The rise and development of industry is closely related to scientific and technological innovation. At present, a new round of scientific and technological revolution and industrial transformation is in the ascendant. Frontier technologies such as general artificial intelligence, life science and new energy are profoundly changing the industrial production function, leading the new direction of industrial development and opening up a new track for industrial development. Only by closely tracking and grasping the changes in the frontier of science and technology can we firmly grasp the initiative of innovation and development in our own hands. At the same time, we should also see that for some time, in order to use their technological advantages to control the value chain of the industrial chain, curb the development of other countries, engage in unilateral sanctions and extreme pressure, interfere with the global industrial division of labor, and build a "small courtyard and high wall" in the high-tech field, which has greatly hindered China’s scientific and technological progress and industrial development. This also shows that only by seizing the opportunity to promote industrial upgrading and constantly improve competitiveness can we improve the resilience and safety level of China’s industrial chain supply chain.

Under this background, actively promoting the development of industrial intelligence will not only help to seize the industrial highland formed by the new round of scientific and technological revolution and push China’s industry to the high end of the global value chain, but also help to enhance the overall strength, quality and efficiency of China’s industry and enhance China’s viability, competitiveness, development and sustainability.

　　At present, China’s development in the fields of 5G and quantum mechanics is in the forefront of the world, with many advantages such as super-large-scale market, huge team of engineers, complete industrial system and strong supporting capabilities. This provides favorable conditions for us to actively promote the development of industrial intelligence. We should seize the opportunity brought by the new round of scientific and technological revolution and industrial transformation, actively promote the digital transformation of the industry, and strive to seize the strategic commanding heights of the global industrial system intelligence. Promote the construction of digital infrastructure, jointly promote digital industrialization and industrial digital transformation, create a legal and regulatory system and market environment that is compatible with the development of digital economy, and promote the development of new formats of digital economy. Further deepen the reform of the scientific and technological system, strive to make new breakthroughs in original innovation, achieve leap-forward development in important scientific and technological fields, and strengthen industrial base reconstruction and major technical equipment research. Enterprises are the main body of scientific and technological innovation and an important force to promote the development of industrial intelligence. It is necessary to further encourage enterprises to increase investment in research and development and better integrate the industrial system and the innovation system; Provide enterprises with digital transformation public services, strengthen digital skills education and training, improve the digital literacy and skills of the whole people, and train more digital talents for enterprises; Give play to the demonstration role of digital transformation of large enterprises and drive the digital transformation of small and medium-sized enterprises through supply chains and other channels.

　　Take the road of ecological priority and green development to promote the green development of industry

　　Green recycling and low-carbon development is the direction of scientific and technological revolution and industrial transformation in today’s era, the most promising development field and the key link to achieve high-quality development. To build a modern industrial system, we must adhere to the concept of green development, seize the opportunity of rapid development of global green economy, green technology and green industry, make good use of green development policy tools, actively and steadily promote peak carbon dioxide emissions and carbon neutrality on the one hand, and cultivate new competitive advantages in green transformation and development on the other.

　　Since the 18th National Congress of the Communist Party of China, China has incorporated peak carbon dioxide emissions and carbon neutrality into the overall economic and social development, and completed the "1+N" policy system of peak carbon dioxide emissions and carbon neutrality. Enterprises in various industries have implemented policies and measures around the goal of peak carbon dioxide emissions and carbon neutrality, strengthened pragmatic actions, and accelerated the transformation of China’s industrial development to green and low carbon. Grasping the general trend of global green development and promoting the green development of China’s industries are the inherent requirements for promoting high-quality development, which is conducive to actively and steadily promoting carbon neutrality in peak carbon dioxide emissions, actively responding to climate change and protecting the ecological environment, and also conducive to cultivating new kinetic energy in green transformation. We must unswervingly follow the path of ecological priority and green development, accelerate the development of green low-carbon industries, vigorously develop green finance, make full use of market-oriented and fiscal measures such as carbon trading, renewable energy green power certificate (green certificate) and environmental protection tax, accelerate the popularization and application of advanced green technologies, and vigorously develop green supply chain; At the same time, we will enhance the synergy of industrial policies, effectively mobilize the enthusiasm of all parties, promote the green development of industries from policies, factors, technologies, markets and other aspects, and strive to cultivate new industrial competitive advantages.

　　Adapt to the new trend of industrial development and promote the development of industrial integration

　　At present, industrial development and its driving mode to economic growth are changing. Looking back on the past few scientific and technological revolutions, it is often that technological progress has formed a major technological breakthrough in a certain industry or field, which has driven these industries or fields to achieve innovative development. The industries that have achieved innovative breakthroughs have alternately become the leading industries that drive economic growth, and the driving force for economic growth comes from the deepening division of labor. For example, the invention of steam engine and internal combustion engine gave birth to textile industry and automobile industry respectively, which developed rapidly and became the leading industries to stimulate economic growth at that time. Different from the past, the new round of scientific and technological revolution belongs to the universal scientific and technological revolution. With the rapid development of digital technology represented by artificial intelligence, cloud computing, blockchain, big data, etc., in the process of rapid development of digital industry, data is also rapidly integrated into production, distribution, circulation, consumption and social service management as a new production factor, which has greatly changed the technical and economic paradigm of all walks of life, promoted the industrial development from deepening division of labor to mutual integration, spawned new industries, new formats and new models, and generated new economic growth points.

　　Industrial integration will also change the industrial structure and economic growth mode. With the deepening of industrial integration, economic growth may no longer be limited to the unilateral rapid development of a certain industry or a certain department, but manifested in the coordination and integration of various industries, so as to jointly improve the quality of economic development from the aspects of improving service quality, improving resource utilization efficiency and meeting diversified needs.

　　In recent years, China’s industrial integration development process has accelerated, its contribution to economic growth has gradually increased, the service level of manufacturing industry has risen, the synergy between supply and demand has been greatly improved, and the consumption level and quality of life of the people have also been greatly improved. The development of industrial integration promotes the transformation of production organization and social division of labor to networking, flattening and platformization, and accelerates the formation of new formats led by platform enterprises; It has spawned new models such as platform design, intelligent manufacturing, networked organization, personalized customization and digital management, which has deepened the relationship between industries; Promoting the synergy between industry and urban development plays a positive role in regional coordinated development. Facing the future, making extensive use of advanced science and technology, continuously breaking down market access barriers, and building and perfecting institutional mechanisms that are compatible with the development of industrial integration will further promote the development of new industries, new formats and new models.

　　Lay an industrial foundation for accelerating the formation of new quality productive forces

　　At present, China is the only country in the world that has all the industrial categories in the United Nations industrial classification, and the output of more than 220 industrial products ranks first in the world, and the world’s largest 5G network, high-speed railway network, expressway network and online retail market have been built. At the same time, however, China’s industrial development is still at the low end of the global value chain, and there are still key core technologies such as "stuck neck". On the new journey, we should adhere to the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, implement the Supreme Leader’s economic thought, focus on the real economy, fill in the shortcomings of industrial development, build a modern industrial system with integrity, advancement and safety, lay a solid industrial foundation for accelerating the formation of new quality productivity, and promote China to win strategic initiative in future development and international competition.

　　Improve the modern infrastructure. Infrastructure is an indispensable public good for industrial development and an important part of modern industrial system. The agglomeration of industries in geographical space, especially the cluster development of specialized suppliers, service providers, financial institutions, manufacturers of related industries and other related institutions in a certain space, can greatly improve the utilization efficiency of infrastructure, effectively reduce the production cost, supporting cost and logistics transaction cost of cluster industries, and produce the spillover and sharing of technology, knowledge and information. Therefore, we should adhere to the guidance of overall optimization and collaborative integration, coordinate the development of traditional and new infrastructure, and create a modern infrastructure system that is intensive, efficient, economical, intelligent, green, safe and reliable, so as to create favorable conditions for China’s industrial transformation and upgrading and cluster development.

　　Fill in the shortcomings of industrial development. Firmly grasp the key core technologies that restrict high-quality development, carry out scientific research, promote short-board industries to supplement the chain, extend the chain of advantageous industries, upgrade the chain of traditional industries and build chains of emerging industries, and enhance the continuity and competitiveness of industrial development. Fully respect the laws of scientific research, improve the allocation of scientific research resources, promote the transfer and transformation of scientific and technological achievements, and implement the main position of scientific and technological innovation in enterprises from the system. We will improve the new national system for tackling key core technologies, organically combine the government, market and society, and make scientific overall plans, concentrate efforts, optimize mechanisms and work together to tackle key problems.

　　Strengthen the open cooperation of industrial chain and supply chain. Strengthening the open cooperation of industrial chain and supply chain is conducive to improving the quality and allocation level of production factors in China and shaping the new advantages of Chinese enterprises in international cooperation and competition. It is necessary to further deepen reform, speed up the construction of a unified national market, break down local protection barriers, promote the orderly transfer of key industries, and optimize the domestic distribution of productive forces. Adhere to global vision, open mind, benchmark international high-standard economic and trade rules, actively create a good business environment, support enterprises to deeply participate in global industrial division and cooperation, promote deep integration of domestic and foreign industries, promote high-level opening of industries, and strive to promote high-quality development of industrial systems in international competition.

　　German automaker BMW’s layoff plan was exposed.

　　On September 19th, Reuters quoted the German magazine Manager as saying that BMW planned to lay off 5,000 to 6,000 people by 2022. According to the above report, this layoff plan will be announced in December, which is part of the cost reduction plan that BMW is implementing. The main place of layoffs is the headquarters in Munich, Germany.

　　In response to the above report, BMW responded that its goal is to maintain the same workforce in 2019 as last year. "We are using layoffs to make the company pay more attention to the future and improve efficiency." At the same time, the company said that it will continue to recruit talents in areas such as autonomous driving and electric vehicles.

　　In March this year, BMW Group launched a cost reduction plan of 12 billion euros. The company said that it will achieve faster processes and a leaner structure, thus improving efficiency, and layoffs are also part of the ongoing plan. When BMW announced the plan, it said that its profit in 2019 would be "much lower" than that in 2018, so it implemented a cost-saving plan of 12 billion euros to help offset the adverse effects caused by trade conflicts and unprecedented investment expenditure on electric vehicles.

　　In order to cut costs, BMW also plans to eliminate some models and reduce research and development time by up to one third. Nicolas Peter, chief financial officer of BMW Group, said: "The automobile industry is undergoing a rapid transformation. If we want to continue to promote change, sustained high profit margins are crucial."

　　Judging from the financial report data, BMW is facing the pressure of falling profits. In the first half of this year, BMW Group’s revenue was 48.177 billion euros, up by 1.1% year-on-year. However, compared with last year’s 5.446 billion euros, earnings before interest and tax decreased by 48.8%, reaching 2.79 billion euros. The profit rate before tax was 5.8%, lower than 12.6% in the same period; The net profit was 2.068 billion euros, down 52.5% year-on-year.

　　BMW also expects that pre-tax profit will drop by more than 10% in 2019. According to BMW, the profit margin of the automobile industry will be between 6% and 8% in 2019, which is lower than the long-term target of 8% to 10%. In 2018, the profit margin of BMW was 7.2%.

　　Comprehensive report by The Paper reporter Bao Yuxi

In the hit film Moon Man, Shen Teng plays Du Guyue as a nobody, but it is such a nobody who finally stands up for others.

In an interview with reporters, Shen Teng said that there is a line in the script-"middleman", which is a summary of Du Guyue. "He doesn’t want to be that particularly top-notch person and feels that this position in the middle is very comfortable." In the end, he was able to stand up. Shen Teng said that love made him make this decision. "I think everyone may sacrifice the ego or the ego. Another is that if he doesn’t do it, he will die with everyone when he returns to earth. Another option for him is to continue to return to the moon. If the whole earth is destroyed and all mankind are extinct, it is meaningless for him to live any longer. In fact, this is a growth, which includes his love for Ma Lanxing and the love of so many people. Everyone on earth watched his live broadcast later. Without these people, he could not live. I think love made him make this decision. "

Although Shen Teng, who had an old injury, did some rehabilitation training before shooting in Moon Man, he still didn’t expect Moon Man to ask for physical strength, especially those movements to be completed on the moon. "If you walk on the moon with Weiya hanging, the essentials you need to grasp are truth. Like your gravity, there is only 1/6 left, which needs to be completed with the help of the whole team."

In the film, Shen Teng’s shot of Du Guyue being beaten by a king kong mouse on the moon contributed a lot of laughter to the audience. In fact, the filming of these dramas was a big challenge for Shen Teng. He said that he didn’t expect that he suddenly became a martial arts actor. "My body, whether it is coordination ability or health, is actually more suitable for shooting stories from the editorial department. It is suitable for sitting and lying there in the house. It is really hard to play this piece."

Although Shen Teng is often beaten by rats in the film, in fact, he is very distressed by the king kong mouse. Shen Teng said that Hao Han, who plays the king kong mouse, was very tired during the filming process. Because he was wearing a kangaroo suit, his stomach was injured and he went to the hospital, which really made him feel distressed for such a faceless role. "He is very hard. He moved to the zoo one year in advance to find the kangaroo feeling, watched TV and read all the information, and then entered the group training four months in advance."

As we all know, as a bridge between users and the digital world, the smartphone operating system is self-evident. If it is not stable enough, it will affect the user experience.

As the world’s leading communication technology company, Huawei has demonstrated strong innovation strength in the field of smart phone operating system, and its HarmonyOS OS system has attracted much attention.

Because unlike other mobile phone manufacturers who customize the Android system, Huawei HarmonyOS is an independent operating system, and it will be completely separated from Android in the future.

Therefore, every upgrade of HarmonyOS OS system will make many users expect value, especially recently, the official version of HarmonyOS OS 4.2 has struck again.

It is reported that Huawei’s Mate50 series, Mate X3 series, P60 series and other nine models are fully open to upgrade the official version of HarmonyOS 4.2 in HarmonyOS, which is undoubtedly a great benefit for Huawei users.

According to the upgrade plan previously announced by Huawei officials, nine models including Huawei Mate50 series, Mate X3 series and P60 series will complete the upgrade of HarmonyOS OS 4.2 in April-June.

Then the unlimited opening of the official version of the upgrade is even more exciting for users who hold these models, at least in terms of update speed, which has accelerated a lot.

It is worth mentioning that these models have previously pushed the Beta version update of HarmonyOS4.2.0.120 in HarmonyOS, with the version number of 4.2.0.120.

It can be said that in terms of the pace of upgrade, the speed of HarmonyOS OS 4.2 is still very fast. Even if you don’t upgrade to everyone’s models this time, the number of models covered by HarmonyOS OS 4.2 version is still very large.

In this case, it is estimated that it won’t be long before the test recruitment will be conducted again, so as to upgrade more models to the new version.

In particular, the pollen of Huawei Mate40 series should be tested and recruited next, so you don’t have to worry about not upgrading.

After all, Huawei Mate30 series, Huawei Nova6 series, Huawei P40 series, Enjoy 50 Pro, Glory 30 and other models are all on the way.

As a very popular model in that year, Huawei Mate40 series has no reason not to update quickly, and the parameters of the product itself are not weak now.

Take Huawei Mate40 Pro as an example, it is equipped with HiSilicon Kirin 9000 high-end dual-mode 5G flagship chip and 5nm process. The CPU frequency is 1 * A77 3.13 GHz+3 * A77 2.54 GHz+4 * A55 2.05 GHz.

At the same time, it also has built-in 24-core ARM Mali-G78 GPU chip and integrated Ba Long 5000 5G baseband chip, covering 11 5G frequency bands, and there is no problem in performance.

Coupled with high refresh rate screen, customized Sony IMX700 sensor, 66W super fast charging, 50W wireless fast charging, wireless reverse charging function, NFC, infrared remote control, stereo double-lift, etc., the comprehensive level is very strong.

That is to say, after upgrading to HarmonyOS OS 4.2, Huawei Mate40 series models will definitely change a lot, just need patience.

There are quite a few models pushed this time, and a lot of pollen has been upgraded. Most of the feedback said that the fluency is very strong.

There are also pollen claims that advertising has decreased, especially the interception function of "shake" advertising jump in the application, which is really very easy to use and very critical.

And some pollen said that after the update to the new version, some changes have taken place in the theme. It can be said that the overall change is indeed greater than the HarmonyOS OS 4.0 version.

However, there are also some pollen that there is some pressure on battery life, and even feel that after updating to the new version, the battery loss is much faster than before.

Moreover, some pollen said that it has been updated to a new version, but many functions are still exclusive to the new machine, such as AI retouching, and there is no way to experience it in the old model.

And some users said that after updating to the new version, they didn’t feel particularly improved, but they felt like they had brushed a version number.

It seems that different models will indeed bring different experiences, and users who have not yet updated need to be psychologically prepared.

Finally, for users with Huawei Mate50 series, Mate X3 series and P60 series, upgrading the official version of HarmonyOS OS 4.2 will be a very worthwhile experience.

Then the question is coming, will everyone upgrade? Welcome to reply to the discussion.

　　[Aika car original]

　　The operation of automobile engine is inseparable from the air intake. As an important fuel injection index of EFI engine, the air intake is almost equal to the automobile power.Under the same circumstances, the more air inhaled in the combustion chamber, the more fuel is burned, and the more horsepower and work are generated.

　　Because the air contains a lot of dust and impurities, the engine needs to set a filter element at the entrance of the air intake, which is what we often call an air filter element (air filter for short). Friends who know a little about cars are no strangers to air filters, but do you know that the differences in air filters will also affect vehicles? The reason is very simple. For cars, air filter is equivalent to the mask we wear. The material is too thin and the dust is not filtered thoroughly enough. And the material is too thick, which will affect normal breathing.On the whole, a good air filter should not only ensure good filterability, but also take into account sufficient air intake.

Introduction to air filtration

　　However, I think that the relationship between filterability and air intake is a trade-off. After all, air filtration materials need to have a certain density to block dust, and in this process, air flow and velocity will be lost.

Second, the cross-evaluation test

　　In this session, we will test the air intake and filterability of several air filters respectively, during which we will use a special decoder to read the engine air intake data, and we will also use some simple tools to observe the air intake changes intuitively.

　　Of course, even without tools, the differences between some products can be roughly seen through static observation.

1. Static comparison

　　Air filter is mainly composed of filter material and sealing ring. Although the structure is simple, the difference in workmanship is not the same. There are several items that can show the details of product workmanship, such as the thickness of filter paper, the uniformity and thickness error of PU foam of sealing ring, and the hardness and softness of sealing ring material, which will directly affect the use effect and service life of air filtration in the later stage.

　　Although the difference between the thickness and hardness of sealing ring can not be directly used as a standard to evaluate the quality of air filtration, the comparison of errors between multiple measurement points and average values can also reflect the manufacturing level of a brand. The error value of original air filter is 0.18~0.27mm, Mann brand error is 0.56~0.85mm, Leopard King is 0.36~0.49mm, and K&N is 0.04 ~ 0.05 mm..

　　It is worth mentioning that the cotton filter material used by K&N is light and thin, and the large surface pores can effectively increase the air intake, while the filter oil just makes up for the defects of the large pores in filterability, achieving the dual effects of high flow and strong filtration, which is also the fundamental reason why the performance of wet filter element is better than that of dry filter element.

　　At this point, the appearance differences of several air filters are relatively clear. K&N air filtration is the best regardless of filter material thickness, glue injection process or various errors. Among the other three air filters, Man Pai ranks second with its high filter paper thickness and glue injection process, but there is still room for improvement in error. In contrast, the original air filter has a strong advantage in error control, but the thickness of the filter paper is thin, which may lead to poor filtration performance. Regrettably, the performance of Leopard King Air Filter in this link is not ideal, and all rankings are hovering in the penultimate position.

2. Comparison of air intake

　　Adequate air intake is an important factor for the engine to maintain normal operation. After entering the engine, air will form a certain concentration of mixed gas with fuel, and the ratio of air to fuel mass that constitutes the mixed gas becomes the air-fuel ratio (the ratio of air mass to fuel mass).

　　Although the EFI engine will adjust the fuel injection quantity through a series of closed-loop control (control mode with various sensors participating in information feedback),Keep the air-fuel ratio at the best state of 14.7:1 as far as possible, but only if the air intake performance of the air filter is strong enough.If the density of filter material is too large, although there will be a large air intake in the early stage of use, dust can easily enter the engine; In the later stage, the air filter is also easily blocked by dirt, resulting in low air intake, which in turn leads to a decrease in fuel injection of the engine and a lack of power.

　　After experiencing the above episode, we can draw a conclusion — —The sealing ring error of air filter will bring some obstacles to installation.Although the error is only within 1mm, the smoothness of installation is directly related to the good impression brought by the air filter brand.

　　Although the difference between the strongest and weakest air intake intensity is not more than 1bft, the difference is very obvious when it is transformed into the specific data of the engine. While measuring the airflow intensity, we also read the idle speed data of the engine when installing different air filters through the decoder.

　　The concept of "load" in the four comparative projects needs special explanation:The load value here does not refer to the resistance overcome by engine operation. In short, the load value is the amount of mixture entering the cylinder. You can think that the greater the load = the more intake air.

　　Generally speaking, the test results of self-made instruments are in high consistency with the engine computer data.In the end, the ranking of the air intake of the four air filters is K&N- Man Brand-Leopard King-Original Air Filter.

　　Although Man brand air filter closely follows K&N in data, due to the characteristics of dry filter element, the intake limit can only be equal to the lowest value of K&N; In this link, Leopard King and the original air filter have obviously opened the distance, especially after comparing the engine data, Leopard King’s advantage is still very gratifying.

shield machineAlso called full-face tunnel boring machine.

This is a sharp weapon for "entering the ground"

However, in China, there are shield machines that can "climb steep slopes"

Let the huge and heavy "steel pangolin" climb upwards.

It’s not an easy task.

How does it climb up without slipping?

How to deal with the excavated slag?

Approaching togetherThe first one in China will "climb the steep slope"

Full-face hard rock tunnel boring machine-"Yongning"

China Railway Industry "Yongning" is the first full-face hard rock tunnel boring machine in China, also known as "steel pangolin".It has a diameter of 7.23 meters, a total length of 122 meters and a weight of 1550 tons.

When a common roadheader digs a tunnel, it can only "go straight" in the horizontal direction. For a roadheader with a weight of 1,000 tons and more than 10,000 parts, every time the slope rises, it is a great test from construction safety to parts design.

"Yongning" excavatedNo.1 diversion inclined shaft,The total length is 927 meters, and the vertical drop is over 550 meters.It is an important step in the construction of pumped storage power station.

The diameter is over 7 meters and the slope is over 36 degrees. There is no successful precedent at home and abroad to dig such a large tunnel in the mountain by mechanized equipment.Next, Yongning has to complete three major challenges ↓

1 How does Yongning climb up?

The climbing mode of Yongning relies on the structure of Parthenocissus tricuspidata. The research team added two four groups of eight "legs" before and after, and there were 16 "feet".

?

In order to make the shield machine "climb to the top of the mountain" safely, more than 50 experts held nearly 40 coordination meetings. After 40 months of research, design and test, in August 2022, the first domestic shield machine that could "climb the steep slope" was successfully rolled off the assembly line.

2. Why didn’t Yongning "slide"?

When the 1000-ton Yongning is heading up the mountain, the most important thing is to ensure construction safety and prevent falling.

There is a huge support on the wall of the cave, which is the double anti-slip system of shield machine. This anti-skid system was applied to "Yongning" after a month of limit test.

To this end, the research team also made an experiment in the field. In order to simulate the operation of Yongning under extreme conditions, a foundation pit with a diameter of 7 meters and a depth of 20 meters was excavated, and the renovation cost millions of yuan.

?

Even if the iron plates on both sides are smooth, the anti-skid system of Yongning can still hold still, which is equivalent to a much higher safety factor.

It can be seen from the red mark on the cave wall that the anti-skid system is reliable after many tests.

3. How did Yongning ship carry out the slag?

When the "Yongning" is driving, the generated slag will roll down the slope at an accelerated speed. If it is not careful, it will cause the gravel to splash, which is extremely risky.To this end, engineers specially designed a slag chute, which was then transported out of the tunnel by truck.

The research team specially installed a sprinkler system to spray water through this sprinkler head. In the process, gravel and dust will be washed in the chute and flow to the bottom of the tunnel.

?

At 16: 18 on December 14th, Yongning opened the No.1 diversion inclined shaft.Yongning successfully completed the excavation task of No.1 inclined shaft, filling the technical gap in the field of inclined shaft construction in China.

Soon, "Yongning" and more than 2,000 builders will embark on a new journey and excavate the No.2 diversion inclined shaft.

Seven out of every 10 shield machines in the world come from China.Today, engineers in China have innovated the shield machine, which can only move horizontally, to be able to go up, down and turn. Praise!
