Foundation pit slope collapse prevention structure and erecting method thereof

Abstract

The invention relates to a foundation pit slope collapse prevention structure and an erecting method thereof. The foundation pit slope collapse prevention structure comprises a rod body, wherein the rod body comprises a fixed rod and movable rods arranged at the two ends of the fixed rod; the whole fixed rod is hollow; the movable rods are inserted and slidably connected into the hollow fixed rod;the ends, away from each other, of the movable rods on the two sides are provided with supporting plates used for abutting against the side wall of a foundation pit; a plurality of annular plates areannularly arranged on the inner wall of the fixed rod and located on the two sides of the fixed rod; one side of each annular plate is fixedly connected to the inner wall of the fixed rod, and the other side of each annular plate obliquely extends in the direction away from the center of the fixed rod; a plurality of elastic rods are arranged on the movable rods in the circumferential direction of the movable rods; the plurality of elastic rods are arranged in the length direction of the movable rods; one end of each elastic rod is fixedly connected to the corresponding movable rod, and the other end of each elastic rod obliquely extends in the direction away from the corresponding supporting plate; and acute angles formed between the annular plates and the inner wall of the fixed rod areused for allowing the elastic rods to move in. The foundation pit slope collapse prevention structure has the advantage of being convenient to erect.

Description

technical field [0001] The application relates to the field of housing construction, in particular to a foundation pit slope anti-collapse structure and a method for erecting the same. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction engineering regulations. [0003] The Chinese patent whose authorized notification number is CN210263065U discloses a kind of house building foundation excavation anti-collapse support structure, including support plates, and threaded sleeves are installed ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following technical defects: the installer needs to twist the screw to complete the drive of the support plate to support the side wall of the foundation pit. When the number of support plates used is large, it will cause the installer to Need to twist multiple screws to rotate, which is not convenient for installation
