China will drive a high speed rail at a speed of 100 kilometers per hour from the bottom of the sea,

At present, the significance of China's high-speed rail has transcended various industries, regions and simple economic fields. China's high-speed rail has become the main strategic lever to take advantage of the overall situation - Eurasian high-speed rail, Central Asian high-speed rail, Pan-Asian high-speed rail and the "Belt and Road", to promote the economic integration of Eurasia and high-speed rail in tandem to promote China's development, but also to promote China, the European Union, Russia and India and other countries to form a new community of interests. In recent years, China's high-speed rail technology has gone global, which has aroused the admiration of people all over the world.

The rapid development of high-speed rail technology has also brought a lot of convenience to people's travel. The development of China's high-speed rail technology proves that the era of China's high-speed rail economy has arrived. <>

High-speed rail construction is a diversified technology in engineering construction, vehicle manufacturing, signal control, operation, maintenance and other aspects. No matter where the technology is imported, China can perfectly integrate and improve it into its own technology, and we can be more perfect than the imported technology in all aspects. <>

In recent years, with the rapid development of China's industry, China has gradually moved from the process of imitation to the road of independent research and development, China's high-speed rail is now comparable to Japan's high-speed rail, and it is not modest to say that it has surpassed Japan, of course, because of the relationship between countries we still need to keep a low profile. There are also many foreign friends who come to experience China's high-speed rail. <>

As more and more countries began to cooperate with China to build high-speed rail, the Japanese became more and more uncomfortable, and even ridiculed China's high-speed rail on TV as stealing from Japan. There was a German present at that time. The Germans retorted on the spot:

Japan used to imitate Germany, which embarrassed the Japanese. At a time when China's high-speed rail was developing rapidly, the Shinkansen, which the Japanese were proud of, was full of holes. Not so long ago, it was reported.

Shinkan in the country of Japan caused cracks in the bogies of trains due to materials at bends and corners. Fortunately, it was discovered in time. If the situation is not good, the high-speed rail will be derailed, and the lives of the Japanese people will be seriously safe.

China's high-speed rail technology is still very good, it is world-class, not only fast, but also particularly stable.

China's high-speed rail technology is indeed very first-class, can be called the world's first, both the speed of high-speed rail and the mileage of high-speed rail construction, are second to none in the world.

China's high-speed rail technology is also among the best in the world, and the high-speed rail runs smoothly and safely, with a good internal and external environment.

Hello netizens, China's first cross-sea high-speed railway is about to open to navigation, the technical difficulty of cross-sea high-speed rail is that the marine hydrological environment is complex, the risk coefficient is high, and it is necessary to detect the undercurrents on the ocean and the geological changes on the seabed. This is several levels more difficult to build, and it is not as simple as building a high-speed rail on land. <>

As we all know, we officially opened the Hong Kong-Zhuhai-Macao Bridge last year, which allowed us to see the great strength of China's infrastructure, and now China's first cross-sea high-speed railway is about to open to navigation, which once again shows the mature development of China's infrastructure technology. This is a cross-sea high-speed railway from Xiamen to Fujian, the design speed of the Fuzhou-Xiamen high-speed railway reaches 350 kilometers per hour, I personally still want to take this high-speed railway, after all, you can see the process of crossing the sea on the road, which makes the group of our national pride double. <>

And we have been rated as infrastructure madness by foreign media, and great projects continue to appear, which also confirms their evaluation. In fact, the construction of these road facilities can only show that China's infrastructure technology is becoming more and more mature, and we didn't even dare to imagine that there would be such a road a few decades ago, just like the sea train in One Piece. So that's why I want to take this train.

And China's Fujian Xiamen is a very beautiful city, so the scenery of this train is also very beautiful, you can see the islands near Fujian and so on the way. However, due to the high speed, it may not be easy to see clearly. Just like there is a beautiful train in Russia that automatically slows down when passing through beautiful places for tourists to see, I think if we can also build such a train, it will also attract a lot of attention.

So this high-speed rail is of great significance, and it's a great thing for our infrastructure. is a landmark work. <>

Therefore, when we see these world-leading projects in our country, we will be proud of our poor and filial piety country.

There are three extremely difficult construction sites for the new Fuzhou-Xiamen Railway to lay tracks, namely Meizhou Bay, Quanzhou Bay and Anhai Bay.

Maybe it's because the sea is relatively large, and you don't know how deep the sea is, but you still have to build a foundation in the sea.

During the National Day holiday, many friends will go out to travel, travel abroad, travel abroad or something.

An undersea bullet train is a transportation facility built on the seabed that can be transported. There are many coastal cities in China, although there is traffic to reach other places for coastal cities, it takes a long time to take a car or a boat. <>

Although the straight-line distance may only be more than 100 kilometers, basically speaking, you need to take a detour by car, and it takes six or seven hours to take a boat. Moreover, there are many coastal cities in China, if these places are connected by submarine bullet trains, then all coastal cities, whether it is the transportation of people or the transportation of seafood, manpower and material resources will be reduced, which will significantly improve China's economic system. <>

The EMU will drive from 100 meters of the seabed, this technical difficulty is very great, because it needs to overcome complex terrain, but also need to dig tunnels through the mountains, the most difficult thing is how to build a channel that can resist water pressure in the sea water with strong pressure, for example, Shantou Bay Submarine Tunnel, it is 9781 meters long, the tunnel is in the 8 degree ** zone, it needs to pass through 17 fault rupture zones, eight of which are active faults, the construction difficulties can be imagined, part of the tunnel exists in the high water pressure area, In the event of a pressure leak, the strong water pressure can directly create a 90-metre-high column of water in the seawater, so can the building be able to withstand such a high water pressure? How can a human work under such a strong water pressure? These are all difficult points in the work.

In addition, in addition to the long-term high-pressure seawater state, the building also needs to take into account the long-term erosion of high salinity in the seawater. <>

The maturity of submarine motor car technology marks that China will be able to build a north-south passenger transport channel in the Pearl River Delta, Haixi, Yangtze River Delta and other coastal areas, which has a far-reaching impact on China's coastal areas, and on a global scale, 70% of the earth is seawater, and the contribution of this technology to mankind is not only to shorten the distance, this is an epoch-making transportation revolution.

Overcome the resistance of water, to accurate design, construction is also particularly difficult, first, to speed up the process, second, save time, third, to make the traffic more developed, fourth, people can have a variety of slag rock He species to choose, the first jujube brigade five, is conducive to the two areas such as the contact of people.

Why is it so fast?

The high-speed rail adopts a bullet-shaped head, and the streamlined body can effectively reduce air resistance.

Dramatically increase the speed of high-speed rail. The second is the power factor, ordinary trains are pulled by the locomotive, while high-speed trains use EMUs.

Each carriage has power, and there is more power. Finally, the track factor is that the track of the high-speed rail adopts seamless welding technology, which avoids the appearance of interfaces and improves the stability of the train, so the high-speed rail can run at a speed of more than 600 kilometers per hour, and sometimes even more.

High-speed rail is roughly divided into power, bogies and brake bogies every other train. In other words, an eight-car train is composed of four power trains and four brake trains, the bogie is the core of an operating mechanism of the high-speed railway, the suspension power of the entire high-speed railway, and then its gear set makes its brakes completely completed in the bogie, and the mechanism of the bogie is also very, very complex and very dynamic. Our traditional train just relies on the locomotive when it travels.

The power to drive the back carriage forward, the carriage itself does not produce power, and the high-speed rail body uses EMU, each carriage can generate power, so when the high-speed rail is running, not only the head of the car can drive, the carriage will also run by itself, and the high-speed rail that each carriage can run by itself is naturally much faster than ordinary trains.

In recent years, with the efforts of the Chinese, the high-speed rail track laying car belonging to the Chinese has become the strongest country in the world with all-night related technology. As the Chinese say, core technology cannot be bought, and if you want to improve the living standards and economic development of the Chinese people, you can only rely on yourself, and only you have mastered the technology. Only then can we break the monopoly and oppression of foreigners on China.

Only when they have mastered the technology themselves can those foreign companies and giants learn how to get along with China. It is believed that with the efforts of Chinese scientific research workers, there will be more and more high-tech equipment and industrial chains belonging to the Chinese, and the high-tech monopolized by foreign countries will gradually be mastered by the Chinese.

Because China's strength is very strong, and it is very powerful in the research and development of high-speed rail, China's high-speed rail will be so fast.

This is because China's high-speed rail has been strengthened in terms of speed and has developed a lot of very high-tech technologies, so it will be fast.

This is because of the research, in the process of research, a lot of high-tech has been added, and it is also because of the facilities inside, it will be so fast.

Because our high-speed rail technology is very perfect, new design schemes are adopted, and the design has been improved, so this situation will occur.

Because China's high-speed rail technology is advanced and the power is sufficient, China's high-speed rail will be so fast.

With a speed of 350 kilometers per hour, the Fuzhou-Xiamen high-speed railway is the first high-speed railway in China and the fastest cross-sea railway in the world. After the completion and opening of the railway, the travel time between Fuzhou and Xiamen will be shortened to less than one hour, and a "one-hour living circle" will be formed between the two cities. The "Golden Triangle" of southern Fujian, Xiamen, Quanzhou, and Zhangzhou, will form a half-hour traffic circle.

The southeast coastal urban agglomeration will form a "** tourism belt". The completion of the Fuzhou-Xiamen high-speed railway will further improve the southeast coastal rapid railway network, promote the interconnection of the Maritime Silk Road with the Yangtze River Delta urban agglomeration and the Greater Bay Area, accelerate the rise of Fuzhou and Xiamen, and inject new impetus into the economic and social development of the regions along the route.

Due to the complex hydrological environment at sea and the high risk factors, the whole track of the Xinfuxia Railway is paved with three sites with extremely high construction difficulties: Meizhou Bay, Quanzhou Bay and Anwan Bridge. To this end, the construction unit adopts the domestic advanced local and adjacent line track laying equipment, and the left and right lines of long tracks are laid at the same time, which improves the operation efficiency by 60% compared with the traditional track laying unit. The daily dispatch can lay about 6 kilometers of long track, laying a solid foundation for the opening of the new Fuzhou-Xiamen railway as scheduled.

To this end, the construction unit adopts the most advanced integrated command and dispatch system in China, integrates wireless network transmission, positioning, navigation and other functions into the dispatching system, and realizes the intelligent, information-based and visual management of dispatching and command. The Fuzhou-Xiamen high-speed railway will shorten people's travel time, shorten the distance between cities, and greatly improve people's travel efficiency. After the completion of the operation, the travel time from Fuzhou to Xiamen will be shortened from the current 1 hour and 40 minutes to about 40 minutes, realizing the one-hour living circle and "integration" of Fuzhou and Xiamen.

The high-speed rail will drive the economic development of Fuzhou, Fujian Province, and the high-speed rail of Fuzhou will connect the provincial capital Fuzhou and the romantic capital Xiamen, the economic development of the two cities will be more rapid, promote the exchange and communication between Fuzhou and the romantic capital Xiamen, and promote the investment promotion and capital introduction between the two cities, talent exchanges, industrial transformation, resource sharing, and contribute to the economic development of the two cities and other cities along the line. At the same time, it can promote the industrialization and urbanization process of Fujian's coastal towns, and bring more opportunities to residents along the line through high-speed rail transportation. The north end is connected to the Hefu Railway and the Wenfu Railway, and the south end is connected to the Xiamen-Shenzhen Railway and the Longxia Railway, which can not only build the Beijing-Fuzhou-Xiamen high-speed railway passenger channel.

It will be closely connected with the Yangtze River Delta, Pearl River Delta and other economic zones to promote the economic development of Fujian Province. The Fuzhou-Xiamen high-speed railway is of great significance to the development and improvement of the southeast coastal railway transportation network.

It will enhance the efficiency of sea freight, and it can also better save costs and save everyone's labor time.

In this way, it will be more convenient when traveling, and it can also drive the economy of the two places and save travel time.

According to the most advanced report, in recent days, the first cross-sea high-speed railway with a speed of 350 kilometers per hour in China is about to start construction, and it is expected to be opened to traffic normally by the end of next year, which is the fastest cross-sea high-speed railway in China. It has promoted the rapid economic development of both sides of the coastal coast.

First, if you want to get rich, you must first build roads. From ancient times to the present, we have a saying in China, the ancient saying is to get rich, first build the road, after hundreds of years of experience of the ancestors, this sentence is very reasonable, if the road is repaired, if there is a better means of transportation, this can promote the exchange and development between each city and each city, save a lot of time, but also improve the economic development between cities, education development, etc.

Second, high-speed rail facilitates people's daily travel. As people's income is getting higher and higher, the quality of people's means of transportation is getting higher and higher, from the previous green train to the later bullet train, and then to the current high-speed rail harmony and other express trains, which brings a lot of convenience to people's daily life, not only saves a lot of time, but also greatly improves the efficiency of travel, the most important thing is that the price of high-speed rail is not very expensive, so that everyone can accept it well, I hope that our country can build a few more high-speed railways for the people. This can also promote the economic development of our country and improve the efficiency of study and work.
