An easy-to-assemble and disassemble foundation pit support structure and construction method

Abstract

The invention relates to an easily assembled and disassembled foundation pit supporting structure and a construction method, belonging to the technical field of foundation pit support. A plurality of column piles are inserted side by side at the bottom position of the side wall of the foundation pit, the top of the column pile is fixed with a cable, the end of the cable away from the column pile is fixed with an anchor column, and the side of the column pile away from the center of the foundation pit is fixed There is a retaining plate, and backfill soil is filled between the retaining plate and the side wall of the foundation pit, and a tensioning assembly is fixed on the ground at the position where the column and pile are far away from the center of the foundation pit. The tightening box is provided with a tightening groove for fixing the anchor column, and the opening direction of the tightening groove is inclined upward toward the direction away from the column pile, so as to achieve the effect of easy assembly and disassembly of the foundation pit support structure.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to an easy-to-assemble and disassemble foundation pit support structure and a construction method. Background technique [0002] Foundation pit support is to adopt support, reinforcement and protection measures for the side wall of the foundation pit and the surrounding environment to ensure the safety of the surrounding environment of the foundation pit and the stability of the soil, and at the same time ensure the construction of the underground structure of the building to meet the needs of the basement construction. space requirements. [0003] Foundation pits include deep foundation pits and shallow foundation pits. The side walls of shallow foundation pits are inclined. The existing shallow foundation pit support structures are as follows: figure 1 As shown, it includes a plurality of piles arranged side by side on the same straight line close to the bottom of ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: before the above-mentioned foundation pit support structure is installed, a groove for placing the tie rods needs to be opened on the ground, so that the anchor columns can drive the tie rods into the ground after they are driven into the ground. , after the anchor column is fixed, refill the soil layer to cover the tie rod, and when the foundation pit does not need to be supported, it is also necessary to dig out the soil layer covering the tie rod on the ground first, and then the anchor column can be removed from the ground Pull out from above, resulting in very inconvenient assembly and disassembly of the entire support structure
