Structure and construction method for temporarily reinforcing soft soil foundation

Abstract

The invention discloses a structure used for temporarily reinforcing a soft soil foundation. The structure comprises two to five layers of steel wire nets. A graded crushed stone layer is paved between each of two adjacent layers of the steel wire nets. The peripheries of adjacent two layers of the steel wire nets are connected through vertically connected iron wires. The invention also discloses a construction method of the structure. According to the invention, the layered-distributed structure with the graded crushed stones wrapped by using the steel wire nets is used for temporarily reinforcing the soft soil foundation, such that construction cost is low, and construction period is short. Therefore, a soft soil foundation construction tight schedule problem can be well solved. The structure and the construction method are suitable for the construction of various soft soil area temporary roadbeds and working platform foundations.

Description

Technical field [0001] The invention relates to a construction structure and a construction method, in particular to a structure and a construction method for temporarily strengthening soft soil foundations. Background technique [0002] Soft soil foundation, especially silt soil, has a very low bearing capacity due to high water content, large pores, and high soil compression. At present, replacement methods, pre-compression methods and various replacement methods are often used in the construction of soft soil foundations. The construction cost of the treatment, replacement method and various replacement methods is very high, and the construction period is longer, and the construction period of the pre-compression method is longer. Some temporary roadbeds and working platform foundations have very high requirements for the construction period. In the project, there is no method that can better solve the tight construction period of soft soil foundation. Summary of the inventio...

AI Technical Summary

Problems solved by technology

[0002] Soft soil foundations, especially silt soils, have very low foundation bearing capacity due to their high water content, large pores, and high soil compressibility. At present, replacement and filling methods, preloading methods and various replacement methods are often used in projects for soft soil foundations. Treatment, replacement method and various replacement methods are very expensive, and the construction period is longer, and the construction period of the preloading method is longer, and some temporary subgrades and working platform foundations have very high requirements for the construction period. In engineering, there is no method that can better solve the tight construction period of soft soil foundation.
