Abstract

The invention relates to the technical field of deep foundation pit support, and discloses a construction method for a combined deep foundation pit support structure, including a reinforcement cage and a lattice column. The construction steps are as follows: 1) forming column pile holes; 2) placing the reinforcement cage Hang it into the pile hole of the column, and correct it so that the reinforcement cage is in the center of the pile hole of the column, and then fix the reinforcement cage; 3) Put the lattice column into the pile hole of the column, and the lower part of the lattice column is embedded in the reinforcement cage Inside, the lowering distance of the lattice column is 2‑4 meters, and the lattice column and the steel cage are welded to form the first welding part; Welding again to form the second welding part; 5) lowering the whole formed by welding the reinforcement cage and the lattice column to the pile bottom elevation; 6) pouring concrete. Under the action of the reinforcement cage, the lattice column is not easy to cause deviation, which ensures the verticality and centering effect of the lattice column, thereby ensuring the pile quality of the cast-in-place pile and improving the overall stability of the support system.

Description

technical field [0001] The invention relates to the technical field of deep foundation pit support, in particular to a construction method of a combined deep foundation pit support structure. Background technique [0002] Deep foundation pit support refers to the support, reinforcement and protection measures adopted for the side wall of deep foundation pit and the surrounding environment in order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. [0003] At present, the supporting structure of deep foundation pits is composed of supporting column piles and supporting beams. The supporting column piles are divided into vertical columns and foundation piles at the bottom of the foundation pit. Cast-in-situ piles are used below the bottom of the pit, and the supporting columns are extended into the range of about 3 meters of the bottom-of-pit piles to form a support system for the deep foundation pit. [0004...
