A foundation pit support structure and method

Abstract

The invention relates to a foundation pit support structure and method, comprising a plurality of pile rows whose lower ends can be inserted into the soil layer below the foundation pit. The plate is fixed so that multiple piles are arranged in rows; a gap is formed between the lower end of the connecting plate and the bottom surface of the foundation pit, and a rotating rod is installed on the upper part of the gap, and one end of the rotating rod can extend into the soil layer of the side wall of the foundation pit In the middle, an unloading platform is formed, and a diagonal bracing member is provided between the other end and the upper end of the pile row to transmit the moment.

Description

technical field

[0001] The invention belongs to the technical field of foundation pit support, and in particular relates to a foundation pit support structure and method. Background technique

[0002] In foundation pit engineering, the most common support method is to use support structures, such as anchor support structures, support support structures and cantilever support structures.

[0003] The inventors have learned that the force-bearing forms of these retaining structures rely on their own strength to resist the lateral force of the soil, and their supporting capacity depends on the strength of the structure itself, especially the cantilever structure, but for structures and soil The interaction was not exploited further. In addition, in the foundation pit project, the drainage system needs to be set up separately. In case of heavy rain or drainage failure, accidents such as foundation pit instability are prone to occur. Contents of the invention
