Abstract

The invention discloses a permanent and temporary combined prefabricated internal support system and a construction method, and relates to the technical field of ultra-deep foundation pit engineeringconstruction. The structure of the support system comprises a foundation pit, an underground continuous wall is arranged on the inner wall of the foundation pit, and a plurality of steel supports arearranged horizontally in the foundation pit; partial permanent structures are arranged at the positions, corresponding to the end parts of the steel supports, of the inner wall of the foundation pit,and temporary structures are connected between the end parts of the steel supports and the partial permanent structures. Aiming at the problems of multiple construction procedures, long maintenance time, slow construction speed, and being incapable of recycling utilization in the prior art, the purpose is to provide the permanent and temporary combined prefabricated internal support system and theconstruction method, and the support system and the construction method have the advantages of fast construction speed and environment-friendly recycling.

Description

technical field [0001] The invention relates to the technical field of ultra-deep foundation pit engineering construction, and more specifically, it relates to a permanent combined assembly type internal support system and a construction method. Background technique [0002] With the continuous advancement of urban construction, building foundation pits in soft soil areas or foundation pits of subway stations will become deeper and deeper. Generally, for the support system in ultra-deep foundation pits in soft soil areas, cast-in-place concrete supports and concrete purlins with higher rigidity are mainly selected, which are safe and reliable. The steel pipe support is generally only used in shallow foundation pits due to its small bearing capacity and poor rigidity. [0003] Concrete supports and purlins for ultra-deep foundation pits mainly have the following deficiencies: [0004] 1. After the structural construction is completed, the concrete supports and concrete purl...
