Reverse excavation from top to bottom! How shocking was the process of building Asia's largest transportation hub in Beijing?

Introduction

There is no end to the development of the city. The city has begun to expand gradually, and new buildings have been set up in this area. With the expansion of the city, the traffic problem is also a relatively big problem. With the continuous influx of modern cars and transportation tools, it is not easy to talk about.

Beijing has always been an international metropolis in China. People from all over the country come to Beijing for travel every day. Beijing's traffic once became a huge problem. Now the Beijing Municipal Government plans to build the largest transportation hub in Asia in the northern suburbs of Beijing to expand more space for Beijing's traffic.

But in this environment, people are very confused about how this transportation hub was built. How did Beijing, the largest transportation hub in Asia, build it?

Does the new largest transportation hub in Asia have to have a symbolic symbol?

The largest transportation hub in Asia is in Beijing.

Now Beijing has expanded to the seventh ring road area. The seventh ring road has been built. There are also some high mountain areas in the seventh ring road area. The traffic in these areas is relatively isolated. Once you go out, it will take a period of time. In addition, if these houses stand in the mountains, they are mainly separated by large vehicles.

Then one day, the newly established Asia's largest transportation hub in Beijing will become a distribution center for these people, and also a large distribution center for vehicles in Beijing to reach the mountain area. Therefore, Asia's largest transportation hub will be built here.

Since this transportation hub is located in a mountainous area, to a large extent, the situation in the transportation hub is concerned. In terms of the establishment of Asia's largest transportation hub, the world's high-speed railway is also to be built on an extreme terrain, especially in mountainous areas or areas with high altitude, so the process of establishing transportation hubs is very difficult.

Not only the planning of the transportation hub, but also the underground construction in the transportation hub will bring some difficulties to the construction. During the construction process, there will be some problems and difficulties, but without these problems and difficulties, the construction personnel will not be able to solve these problems and difficulties, and will not accumulate more experience.

Therefore, in the face of difficulties, we must have a calm heart, correct attitude and prepare for the next step of construction.

If everyone can correct their attitude, the difficulties will be solved. Therefore, the project of building a transportation hub in Beijing began smoothly.

Carry out construction of underground works.

The first is to carry out the project. Since the transportation hub is built in a relatively high mountain area, the first step of starting construction here must be to dig out all the soil and debris on the mountain. During the removal process, snakes, rats and some poisonous plants may also be dug out. These poisons cannot be thrown away directly after being dug out, but must be buried deep underground first.

When the transportation hub building starts to be built, these buried things should be abandoned to avoid bringing crisis to the transportation hub building.

During the construction of the transportation hub, a layer of flat soil cannot be paved again, because the sun and rain will press the soil on the ground, which will make the soil on the ground hard and firm.

Therefore, after the earth on the ground is excavated, the staff will still collect a part of the earth, and when the building is completed, the soil will be covered again, so that part of the cost of the transportation hub in the later period can be saved.

When the local excavation is completed, the soil in the mountain area is relatively soft, so the excavated soil piles are relatively high, and special personnel should be assigned to clean up some small debris.

In the process, the work of manual cleaning is to classify the soil piles and take away the small sundries. After the workers take away some small sundries, the remaining soil piles are relatively large. These soil piles can be removed by machinery, which can save manual effort.

Finally, with the cooperation of various machines, the terrain of the transportation hub is almost sorted out.

Underground buildings.

After the terrain of the transportation hub is sorted out, the next step is to build the underground buildings of the transportation hub. For underground buildings, first of all, the foundation below the building should be well laid. The pipeline is built on the foundation below this, so the foundation is very critical.

Before the foundation is built, the soil around the foundation must be excavated first. Digging the soil of this foundation is like digging the foundation. When digging the foundation, the excavation must be very straight. When digging, all the stones and hard soil inside must be removed. The staff who determines the foundation must also use a horn to measure the angle.

After the foundation is excavated, the pipeline construction can begin. We often see such curved roads in underground tunnels. However, when building underground tunnels, the curved roads should be excavated first in the underground, then modeled, and then directly built the pipeline to the curved road next to the model.

The pipes are generally built in the inner layer, and the outer layer is used as the protective layer of the interlayer. This can reduce the damage on the ground on the one hand, and also prevent the damage of the underground pipes from being discharged into the underground drainage pipes when they are damaged.

Therefore, the construction of underground transportation hub is very difficult, but the project construction personnel successfully built this huge underground transportation hub through unremitting efforts.

epilogue

The establishment of Asia's largest transportation hub has made many people very curious about how this huge transportation hub was established. If there is a largest transportation hub in Asia, there must be a landmark building, so that people can find it at once, and at the same time, people can have a strong impression of this transportation hub.
