What to do about airport runway subsidence repair?

The house is the place where we live, and its security is closely related to our personal and property safety. House collapse events occur from time to time, the greater reason is nothing more than: illegal additional layer construction, shoddy construction, service life is too long and other reasons. I believe that everyone has not seen the phenomenon of airport runway subsidence repair, but in fact, the house will have the possibility of tilting, then let's take a look at what to do after airport runway subsidence repair!

First we need to know why the house is tilting. Nowadays, when we build a house, we lay the foundation first (with the exception of some older houses), then a problem with the foundation can cause the whole house to sink. If it is uniform subsidence then it is not so serious, but if it is not uniform subsidence then it will lead to a tilting situation, and the tilting amplitude will continue to increase due to gravity until it becomes a dangerous house.

The first way to deal with the tilted phenomenon of the house is to strengthen the foundation. The following methods can be used:

1. Grouting reinforcement method

Grouting reinforcement method is a relatively common method. Its principle is to drill holes into the ground and then inject grouting grout, and rely on the pressure of grouting to spread the grout to the surrounding cracks to achieve the effect of improving the integrity of the ground and the strength of the foundation. The advantages of this method are simple construction technology, low cost and easy operation.

2, anchor static pressure pile method

Static pile with anchor bolt is a new method of foundation strengthening in recent years. Its principle is to drill the pile hole and anchor hole in the ground, plant the anchor bolt, and then press the prefabricated pile into the soil until the depth reaches the design requirements, so as to connect the pile with the foundation and achieve the effect of improving the bearing capacity of the foundation.

There are many ways to strengthen the foundation, which will not be listed here. A tilted house can be lifted upright after the foundation is strengthened, that is, a cap is poured next to the column and then the connection between the column and the ground is disconnected, and then jacks are used to lift the house upright to the normal amplitude.
