Foundation pit supporting structure and construction method thereof

Abstract

The invention discloses a foundation pit supporting structure and a construction method thereof. The foundation pit supporting structure comprises a plurality of supporting assemblies, wherein each supporting assembly comprises a bottom plate, a protective plate, a top plate and a supporting assembly, the bottom plates are fixedly arranged at the bottom of a foundation pit through preset fixing columns, a plurality of inserting plates are arranged on the sides, close to the side wall of the foundation pit, of the bottom plates, the inserting plates are inserted into the side wall of the foundation pit, a plurality of inserting rods are arranged on the sides, close to the bottom of the foundation pit, of the protective plates, the inserting rods penetrate through receding holes formed in the bottom plate in advance and are inserted into the bottom of the foundation pit, a plurality of clamping plates are arranged on the sides, away from the bottom of the foundation pit, of the protective plates, the clamping plates are clamped with through grooves formed in the top plate in advance, first through holes are formed in the inserting plates, second through holes coaxial with the first through holes are formed in the top plate, fixing piles are arranged between the first through holes and the second through holes which are coaxially arranged in a penetrating mode, and the supportingassemblies are connected between the bottom plates and the protective plates. According to the foundation pit supporting structure, the construction process can be continuous, the construction periodof the foundation pit is effectively shortened, and the construction cost is reduced.

Description

technical field [0001] The present application relates to the technical field of foundation pit engineering, in particular to a foundation pit support structure and a construction method thereof. Background technique [0002] During the excavation process of the foundation pit, the surrounding soil will inevitably be deformed, which will affect the surrounding buildings and underground pipelines, and seriously endanger its normal use or safety. 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 adopted for the side wall of the foundation pit and the surrounding environment. [0003] The existing foundation pit support technology usually adopts bored piles, and horizontal reinforced concrete supports are set in the pit to improve the rigidity and stability of the foundation pit enclosure structure, better control the foundatio...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the method of bored cast-in-place piles needs to wait for the cast-in-place piles to be solidified and formed and maintained during construction, so that the construction of the foundation pit support structure cannot be carried out continuously, thus prolonging the construction period , which increases the project cost; therefore, it can be further improved
