Foundation pit inclined strut device and foundation pit inclined strut construction method

Abstract

The invention provides a foundation pit inclined strut device and a foundation pit inclined strut construction method. A foundation pit is internally provided with a building envelope. The foundationpit inclined strut device comprises a pipe body, braced wings, a holding-up hammer and delayed coagulation slurry, wherein the pipe body is provided with an opening end and a closed end, the closed end is anchored into a foundation of the foundation pit, the pipe body is obliquely supported by the building envelope, and insertion openings are formed in the closed end; the braced wings are hinged to the inner side wall of the closed end; the holding-up hammer is provided with an abutting end, the abutting end is inserted into the pipe body through the opening end and then abuts against the braced wings, and so that the braced wings stretch to the outer side of the pipe body through the insertion openings; and the delayed coagulation slurry is poured into the pipe body and flows to the insertion openings to wrap the braced wings. According to the foundation pit inclined strut device and the foundation pit inclined strut construction method, the problem that a traditional enclosure systemof a campshed and horizontal inner supporting beams is not beneficial to construction of the internal structure of the foundation pit is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a foundation pit diagonal brace device and a foundation pit diagonal brace construction method. Background technique [0002] With the increasing shortage of land for urban construction and the rapid development of underground space, foundation pit engineering has attracted more and more attention from engineers. The traditional enclosure system uses row piles + horizontal internal support beams. For the traditional enclosure system, because the horizontal inner support beam needs to be installed in the foundation pit, the engineering cost is high, and it is not conducive to the internal structure construction in the foundation pit, the construction space of the machine is limited, and the construction progress is slow. Contents of the invention [0003] In order to overcome the defects of the existing technology, a foundation pit diagonal brace device and a foun...
