Anchorage-type foundation pit reinforcing structure and construction method thereof

Abstract

The invention discloses an anchorage-type foundation pit reinforcing structure and a construction method thereof. The anchorage-type foundation pit reinforcing structure comprises a plurality of support piles, a top beam, a plurality of anchorage piers, tie rods and anchor rods, wherein the top beam is fixedly connected with the support piles respectively to form a support structure; a preset distance is kept between each anchorage pier and the support structure; each anchorage pier is anchored in a soil body on the outer side of the foundation pit; the tie rods, the anchor rods and the support piles are in one-to-one correspondence to the anchorage piers; two ends of each tie rod are fixedly connected with one anchorage pier and the top beam respectively; two ends of each anchor rod are fixed on one support pile and one anchorage pier respectively. Therefore, according to the anchorage-type foundation pit reinforcing structure, on the basis of fully utilizing the support structure, the integrity, rigidity, bearing capacity and bending resistance of the whole support system are improved and the reinforcing cost is reduced; meanwhile, section construction can be realized without influence on underground structure construction; the reinforcing effect is quick and good; the convenience in popularization and use is realized.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an anchor type foundation pit reinforcement structure and a construction method thereof. Background technique [0002] The foundation pit refers to the space below the ground excavated for the construction of the foundation and basement of buildings (including structures). location. [0003] Foundation pit support refers to the support, reinforcement and protection measures adopted for the side wall of the 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. In the prior art, row pile support is a common form of support. However, in the actual construction process, the supporting structure of the foundation pit is often damaged when the load-bearing pressure is too large or the conditions of the surrounding environment and groundwater change suddenl...
