Connecting structure between foundation pit supporting pile and basement exterior wall and construction method

Abstract

The invention discloses a connecting structure between a foundation pit supporting pile and a basement exterior wall and a construction method, and relates to the technical field of civil engineering. The connecting structure comprises the foundation pit supporting pile, a top beam and the basement exterior wall mounted at the top end of the foundation pit supporting pile; a cross beam is mounted on the side, close to the foundation pit supporting pile, of the top beam and located on the side, away from the foundation pit supporting pile, of the basement exterior wall; a clamping mechanism is arranged between the cross beam and the basement exterior wall and used for fixedly connecting the cross beam with the basement exterior wall; and the clamping mechanism comprises an inserting piece and an embedding piece, wherein the inserting piece is used for being inserted into the basement exterior wall and the cross beam, and the embedding piece is connected with the inserting piece and embedded into the cross beam. The structural composition is simple, the manufacturing cost is low, the overall stability of the structure can be enhanced through the ingenious connecting relation, and underground water buoyancy can be offset easily; and meanwhile, during construction, operation is easy, convenient and fast, the tedious construction steps can be omitted, meanwhile, the strength of the structure can be enhanced, and durability is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a connection structure and a construction method between a foundation pit support pile and an outdoor wall of a basement. Background technique [0002] 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. With the rapid development of urban infrastructure and the continuous expansion of the basement space of buildings, foundation pit support technology has also been continuously improved. During the construction process of the foundation pit supporting structure and the basement in the foundation pit in the prior art, the internal support that blocks the upward construction of the external wall must be disassembled, and the external wall is co...

AI Technical Summary

Problems solved by technology

During the construction process of the foundation pit support structure and the basement in the foundation pit in the prior art, the internal support that blocks the upward construction of the external wall must be dismantled, and the external wall is repeatedly constructed upwards, the internal support that blocks the external wall is removed, and the internal support that blocks the external wall is removed at regular intervals. The process of pouring a floor slab at a height until the basement roof is poured on the top surface of the basement exterior wall, resulting in the basement roof being higher than the crown beam of the foundation pit

In the existing technology, in order to offset the buoyancy of groundwater, the strength of the mechanism is very high, so it is necessary to set up multiple piles, the cost of consumables is high, and the manufacturing process is cumbersome
