AI Technical Summary

Technical Problem

The existing foundation pit support structure cannot effectively support the support frame and the middle area of ​​the frame inner plate when the foundation pit deforms, resulting in the failure of the support effect. In addition, the underground foundation exerts pressure on the inner wall of the bottom of the foundation pit, causing it to sink and affecting stability.

Method used

The underground foundation and pit support structure are integrated. Through the combined design of support frame, support structure, bottom stabilization structure, restraint structure and support inner plate, the pit inner wall is supported and stabilized by components such as anchor bolts, threaded rods and rotating cylinders, so as to avoid deformation and sinking.

Benefits of technology

It effectively supports the inner wall of the foundation pit, prevents deformation of the support frame and depression of the inner wall at the bottom of the foundation pit, and improves the stability and compressive strength of the foundation pit and underground structure.

Abstract

This invention belongs to the field of foundation pit support and underground structure technology, and in particular, it is an integrated structure and method for underground foundation and foundation pit support structure. It includes a foundation pit located on the ground, with an underground foundation on the inner wall of the bottom of the pit. Four support frames are provided within the foundation pit, and each of the four support frames is used to support one of the four inner walls of the foundation pit. In this invention, the upper, middle, and lower parts of the support frames are supported sequentially by a support arm, a first connecting seat, and a second connecting seat, thereby ensuring the stability of the support frames. Furthermore, the cooperation of the first foundation ring, the bearing connecting plate, and the first bearing plate increases the contact area of ​​the inner wall of the foundation pit bottom, preventing deformation of the inner wall of the foundation pit bottom.
