Why was there never a earth moving truck when the subway was built? Where did the excavated soil go?

In the downtown area of the city, trucks are not allowed to enter and exit, because it will seriously hinder the progress of traffic, and it will lead to serious traffic jams, so this is the reason why we have not seen vehicles transporting earth blocks on the road. There is also a special equipment created in China for the complete construction of the subway, the name of this mechanical group is called the shield machine, which is a complete equipment, which can complete a series of operations such as digging holes and treating waste soil.

With the arrival of the subway, people's travel has become more convenient, before to the morning rush hour of commuting, many people will be blocked on the road, anxious, since there is a subway, the phenomenon of urban traffic congestion has been alleviated a lot. And the subway ticket is still very cheap, almost everyone can afford to sit, so many first- and second-tier cities are building subways, and the subway is built underground, does not occupy urban construction land, is to dig a tunnel underground.

It's because the earth-moving trucks are already out, and they will add a little glue to the excavated soil and it will disappear.

In fact, many problems in life are closely related to everyone, but you may not pay much attention to these things. If you think about it, you might find these questions really interesting. When building the subway, a lot of soil was dug up, so what about the soil that will be go?

What will it do?

In fact, I am also very interested in this issue, and we all know that daily travel is also very necessary, but now people are more demanding speed, and if the means of transportation are very inconvenient, then everyone needs to spend a lot of time. Therefore, the country has actually invested a lot of money and time in the research and development of various means of transportation, such as subways and high-speed rail, which actually brings a lot of convenience to everyone. In fact, when building the subway, it also needs to be excavated, and a lot of soil will be dug up in the process, but everyone actually does not see this soil in life.

In fact, there is no way to use up these things to build the subway, and the remaining things may be laid on the construction site, or put on the urban greening construction work.

In fact, the wall next to the subway must be very strong, so that it can bear a certain weight, and the structure of the subway itself is also relatively special. Therefore, the soil can be used continuously, so that a lot of money can be saved to a certain extent, and the soil may be sold, of course, it may be directly used to build buildings or pave roads.

So you don't have to worry that the soil you dig up will be wasted, because the soil will actually be used elsewhere. The reason why many people can't see the excavated soil is actually because the soil is only transported out at night.

It will be used for construction, or it will be used for greening, and it will be used to pave roads, and some of the sand or stones that have been dug up will be sold.

Most of this soil is used in the subsequent subway construction, and a lot of soil is also needed to build the subway, and most of the soil will come in handy, so that the subsequent construction does not need additional transportation soil, and the excavated soil can be used.

It will be used in some construction sites, and later it can be used normally, to build houses, and it can also be used to sell and make building materials.

I think it's going to be used in the dirt yard, and it's going to be used to make land, it's going to be used to build houses, and it's going to be sold.

It should be used to build a house or do something else. Anyway, these soils are very useful.

The excavated soil will be used in some construction sites. Will be used for renovation.

1.Some of the outbound transportation and muck transportation vehicles all start in the early morning. Part of it is to be saved for later use.

2.In order to ensure that the traffic road is clear during the day, it ends by 6 a.m. The road surface at the entrance and exit of the muck transport vehicle must be hardened, the drainage pipe must be buried for washing the transport vehicle, and the transport vehicle must be covered with colored stripe cloth to prevent the muck from being sprinkled on the road during transportation.

The whole vehicle is equipped with GPS GIS monitoring and management system.

3.When building a subway in some cities, as long as the shallow construction is supported, the construction method will be "excavated", and this kind of excavation operation space will be larger than the actual space, and the soil backfill will be needed after the station is completed, so in order to save the soil, it will generally choose to pile up and store nearby, and use it directly in the later stage.

4.There is a special storage place for the muck or on some construction sites under construction. This is because some construction site foundation pits need to be backfilled with muck.

There are generally the following three situations for digging the soil of the subway: 1. The soil of the subway will be transported to the slag yard on the outskirts of the city. 2. If there are other projects that require soil, the relevant parties will deal with the soil in a first-class way.

3. Earthwork balance: the soil dug up during the subway construction will be used back into the project.

Metro

The subway is a fast, high-volume, electrically powered rail transit built in a city. The world's first metro was the Metropolitan Underground in London, England, which was built in 1863.

Subway trains run on fully enclosed lines, and the lines located in the central city are basically located in underground tunnels, and the lines outside the central city are generally located on viaducts or on the ground.

The subway is an urban rail transit system (METRO) that covers all kinds of underground and above-ground right-of-way in urban areas, and is called "MRT" by the Taiwan Metro.

The soil dug up during the construction of the subway will be transported to the ground and then piled up together for backfilling, because in the subsequent construction of the subway, there are many places that need to be filled with soil, and finally some soil that is really not available will be transported to other places.

The subway is a fast, large-volume, electrically driven rail transit built in the city, the train runs on a fully enclosed line, and the line located in the central city is basically located in an underground tunnel.

The subway is an urban rail transit system that covers all kinds of underground and above-ground right-of-way exclusive, high-density and high-capacity urban rail transit systems, which is called "MRT" by the Taiwan Metro in China.

In addition to the subway, it also includes elevated railways or railways laid on the road, so the subway is exclusive to the right of way and has no level crossing, which is also a fundamental sign that distinguishes the subway from the light rail transit system.

Let me explain in detail why the subway is being built underground but there is no earthmoving car.

In addition to pulling to the fixed dump site in the suburbs, the muck company will also contact the construction site that needs to fill the soil, so that the soil can be pulled to earn a profit, and the soil can be sold to earn another money. Sometimes it is also dealt with nearby, such as wasteland that is not planted or fenced off construction sites, but it is usually locals who dare to do this. In this way, they can save money and not have to pull it out, and maybe they can make a profit when the construction site starts.

Now some engineering construction requires a large amount of earthwork, such as: road repair, island filling, brick burning, and earthwork is not everywhere can be dug up, so the soil dug out of the subway is "money", no need to worry about selling, because although the soil excavated by the subway is more, it is far from enough than the earthwork needed to build roads and fill the island! If the soil pulled out from one construction site is directly transported to another construction site and sold, it is the most profitable way, that is, it saves storage costs and secondary loading costs!

Because the soil dug up by the subway is generally pulled away at night, the muck truck is basically not allowed to go in the urban area during the day! Moreover, most of the muck trucks are now covered with tarpaulins, so it is not easy to see what is being pulled. Another is that the construction site is generally closed, even if there is a car inside, you can't see it from the outside!

The excavated soil is stored in a fixed area during the day, and the muck transportation company is transported out by car at night, (the muck transportation company can generally have a social background, all parties have done a good job, and all kinds of documents are also available, otherwise the urban management traffic and the like are always looking for trouble).

Nowadays, many cities are building subways, and it is inevitable that a large amount of muck will be generated during the construction process. However, we rarely see earthmovers and there is no garbage on the road. Why? The earth emerges from **?

We all know that there is a lot of traffic in the city during the day and the traffic is heavy. In some places, even large trucks are banned. At night, we all rest at home, and the street traffic is more convenient.

Trucks usually start work late at night. In addition, the earthmoving truck will be covered with a tarpaulin to prevent the scum from falling. Even if there is debris falling, it will be cleaned up in time.

Of course, we don't see earth-moving trucks and dregs.

At present, the shield machine will be used in the construction of the subway, and the shield machine will continue to penetrate deep into the soil layer, and part of the soil will be squeezed around, so there is no need to deal with it. Other earthwork shield machines supply water through the upper pump during the excavation process. The mud becomes mud and is sent outside by elevator to be collected.

Finally, the water is removed through the sedimentation tank, which is not only convenient for excavation, but also can effectively prevent dust from flying.

Of course, some railway construction has a large amount of earth and stone, and it will be transported out with a gantry crane. It can be transported out of the city at night. Generally speaking, before the construction of the subway, the engineering party will arrange the direction of the soil.

Some are transported directly to the dump site, while others can be dumped directly in the suburbs of which kilometer. Part of it will be ** to the construction site that needs to be filled, which can be used as a secondary use.

The construction of the subway is a great project for the benefit of the people of the city. During the construction period, the disturbance to people's lives is minimized, but the control is relatively strict.

The underground subway is being repaired, but the earth-moving trucks and muck transport vehicles are not visible, and the road surface at the entrance and exit of the muck transport vehicles must be hardened, and drainage pipes must be buried for washing the transport vehicles.

The transport vehicle must be covered with colored striped cloth to prevent the muck from being scattered on the road during transportation.

You were sleeping when they were carrying soil at night.

Luck at night. Just look at the ground to see if there is any falling soil.

The earth-moving trucks go underground from other places, and you can follow the driver to experience it.

The earth-moving trucks have gone underground from other places.

Why can't you see it? A small number of earthmovers, most of which were taken away by the shield machine, were taken away from other places.

If you want to see it, you can follow the driver to experience it.

There must be a special place.

Do you know why you can't see earth-moving trucks when you build a subway? After reading it, solve the doubts of many years!

Of course, you don't know the time period of transporting soil when you are sleeping
