Abstract

The invention provides a soil body protection structure between foundation pit support structure cast-in-place piles. The soil body protection structure comprises a plurality of grid frames and a plurality of connecting ribs, wherein all the grid frames are arranged at intervals from top to bottom, and the two ends of the grid frames are used for being fixedly connected with two adjacent cast-in-place piles; all the connecting ribs are vertically spaced, and the connecting ribs are fixedly connected with all the grid frames; and the grid frames and the connecting ribs which are fixed to a whole are used for reinforcing a soil body between the cast-in-place piles so as to prevent the soil body between the cast-in-place piles from sliding off. According to the soil body protection structure,the technical problem that a soil protection measure of an existing soil body protection surface layer cannot be suitable for large spaces between the cast-in-place piles is solved.

Description

technical field [0001] The present application relates to the technical field of foundation pit construction in construction engineering, in particular to a soil protection structure between cast-in-place piles of a foundation pit support structure. Background technique [0002] In the foundation pit engineering of urban rail transit and industrial and civil buildings, the foundation pit support structure is used to protect the soil of the foundation pit. The foundation pit support structure at least includes a plurality of cast-in-place piles arranged at intervals. Normally, the soil protection surface between cast-in-situ piles is composed of steel mesh, hanging mesh reinforcement, transverse reinforcement, soil reinforcement nails between piles and sprayed concrete surface. The thickness of the concrete surface is generally 50-100mm. The concrete strength grade is C20. The above-mentioned soil protection measures of setting the soil protection surface layer between the ...
