Why didn't the construction team hit the foundation when digging the subway tunnel? Eye-opening after reading

Changes in the world will always bring us different surprises and reflections, but many times we haven't had time to see them, and these beautiful landscapes disappear in front of our eyes. People's life is very short, if you just immerse yourself in work, it is easy to miss these scenery. Let the editor accompany you to see a different and colorful world from the anecdotes that happen every day. Hello everyone, welcome to this episode!

With the prosperity and development of the economy, China's infrastructure is constantly improving, and subways can be said to be all over the country. However, many people are curious about this matter, that is, why did the construction team not hit the foundation when digging the subway tunnel? Eye-opening after reading!

We all know that the subway is built underground, and there are many buildings on the ground, so it is inevitable that the foundation will hit the foundation during the construction process, but why does this never happen to the Chinese subway? In fact, when building a subway, Chinese engineers will first conduct geological surveys to see if the conditions here can make it possible to build a subway. If conditions permit, those buildings on the ground will be avoided first when planning the route.

If it is unavoidable, engineers will first intercept a part of the building foundation, and then choose stronger materials to build the subway tunnel. In this way, even if the subway passes through these buildings, they can be well supported without any impact. In addition, when we built the high-speed rail, we have been pursuing the balance between the line and the ground, so it is very rare to encounter the foundation of a high-rise building. I don’t know if my friends understand it now. After reading it, I really have to praise Chinese engineers.
