Construction method of fabricated underground diaphragm wall

Abstract

The invention discloses a construction method of a fabricated underground diaphragm wall. The construction method comprises the following steps of prefabricating a fabricated underground diaphragm wall structure, carrying out pre-trenching or pre-stirring of a soft soil stratum, inserting the fabricated underground diaphragm wall structure into a trench or the stratum through fabricated underground diaphragm wall structure insertion equipment for connection, excavating a foundation pit, carrying out pouring on crown beams and permanent and temporary combined purlin structures, erecting supports in a following mode, constructing a waterproof layer and a body structure, and then dismantling a supporting structure. According to the construction method, construction is flexible, the structureis simple, and the construction process is reliable; space occupation of a construction site, for example, space occupation of steel bar processing and concrete pouring can be reduced, influences on the surroundings are reduced, the mechanical level and construction efficiency of a project can be improved, the workload of the construction site is reduced, moreover, the underground diaphragm wall pouring quality can be improved, and the project scrap rate is decreased; and the construction method has high applicability and operability and is safe and reliable.

Description

technical field [0001] The invention belongs to a construction method of an underground diaphragm wall, and in particular relates to a construction method of an assembled underground diaphragm wall riveted with a slot guide sleeve. Background technique [0002] my country's urban construction is developing rapidly, and the deep and large foundation pit projects involved in commercial residences, urban rail transit stations, etc. have a wide demand for the enclosure structure type of ground connection wall, but at present, with the increasingly tight urban space, the environmental protection requirements are becoming more and more urgent , safety, construction period and other requirements are becoming increasingly stringent, construction site technicians and human resources are becoming increasingly scarce, and the traditional construction method of connecting walls can no longer fully meet the needs of urban construction. In the soft soil area where the construction site is ...

[0002] my country's urban construction is developing rapidly, and the deep and large foundation pit projects involved in commercial residences, urban rail transit stations, etc. have a wide demand for the enclosure structure type of ground connection wall, but at present, with the increasingly tight urban space, the environmental protection requirements are becoming more and more urgent , safety, construction period and other requirements are becoming increasingly stringent, and there is an increasing shortage of technicians and human resources on the construction site. The traditional ground-to-wall construction method can no longer fully meet the needs of urban construction.
