Steel plate and concrete diaphragm wall and construction method thereof

Abstract

The invention discloses a steel plate and concrete diaphragm wall and a construction method thereof. The steel plate and concrete diaphragm wall is formed by buckling a plurality of steel plate and concrete diaphragm wall units end to end. Each steel plate and concrete diaphragm wall unit comprises an externally-wrapping steel plate barrel, concrete poured inside the corresponding externally-wrapping steel plate barrel, and shearing-resistant pins arranged on the inner side of a main steel plate body of the corresponding externally-wrapping steel plate barrel. Each externally-wrapping steel plate barrel is a cuboid sleeve which is composed of two main steel plate bodies, a straight steel plate body and a steel plate body with the two ends being provided with hooks. According to the steel plate and concrete diaphragm wall and the construction method thereof, construction cost is lowered, pollution is avoided, and there is no need to assemble reinforcement cages on the site, so that time and labor are saved; moreover, the concrete is poured inside each sleeve, and thus the pouring quality can be guaranteed easily.

Description

technical field [0001] The invention relates to an enclosure structure of a foundation pit project and a construction method thereof, in particular to an underground continuous wall structure and a construction method thereof. Background technique [0002] At present, when constructing deep and large foundation pits, reinforced concrete continuous walls are usually used as the enclosure structure. During the construction of this continuous wall, it is necessary to excavate groove sections, use mud wall protection, place steel cages, and pour concrete underwater. Therefore, When the traditional underground diaphragm wall is used as the enclosure structure, there are the following defects: 1. The underground diaphragm wall groove section needs to be excavated during construction, so that the construction is time-consuming, laborious and expensive; 2. The mud wall is required to form the groove, which is easy to cause Environmental pollution, and high cost of disposal of waste ...
