Abstract

The invention relates to a foundation pit supporting structure and a construction method thereof. The foundation pit supporting structure comprises a first supporting plate, a second supporting plate,sliding rods, a limiting assembly and supporting assemblies. The moving direction of the sliding rod located on the first supporting plate is perpendicular to the second supporting plate. The movingdirection of the sliding rod located on the second supporting plate is perpendicular to the first supporting plate. Multiple first limiting grooves are formed in the first supporting plate. Multiple second limiting grooves are formed in the second supporting plate. Limiting plates are mounted on the sliding rods, and limiting holes are formed in the limiting plates. Limiting assemblies comprise limiting rods. Each supporting assembly comprises a supporting part and second sliding blocks, wherein one second sliding block is in sliding connection with the sliding rod located on the first supporting plate, and the other second sliding block is in sliding connection with the sliding rod located on the second supporting plate. The foundation pit supporting structure has the effect that the selfsupporting strength can be changed according to design requirements conveniently.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a foundation pit support structure and a construction method thereof. Background technique [0002] At present, during the excavation process of the foundation pit, it is easy to cause the deformation of the surrounding soil, which will affect the surrounding buildings and underground pipelines. The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. [0003] Related technologies such as a foundation pit support structure announced in the Chinese invention of the notification number CN104294828B, which includes a base plate, a support base, a support member, a support frame, a rectangular tube and a guard plate, and the support frame incl...
