Construction method for opening enclosure structure of underground diaphragm wall of subway station

Abstract

The invention relates to the technical field of subway construction, in particular to a construction method for opening an enclosure structure of an underground diaphragm wall of a subway station. Theunderground diaphragm wall of the station is divided into unit blocks within the subway station opening range, and cutting holes and hoisting holes are drilled through a water drill, so that pollution caused by flying dust generated by mechanical cutting in traditional construction is avoided; a metro station is cut into unit blocks within the starting range through a rope saw, and all the unit blocks are hoisted and dismantled layer by layer from top to bottom through hoisting holes in the unit blocks; and finally the underground diaphragm wall is chiseled off in the range of the connectingpart of the auxiliary structure and the station main body structure, a reserved connector of the main body structure is found out, and reinforced concrete of the auxiliary structure bottom plate, sidewalls and a top plate is constructed. Construction personnel are few, the construction efficiency is high, the labor intensity is low, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of subway construction, and more specifically relates to a construction method for opening an enclosure structure of an underground diaphragm wall of a subway station. Background technique [0002] As my country's urban infrastructure construction continues to increase, the scale of urban subway construction continues to expand. Urban subway construction is affected by many factors such as pipeline relocation, traffic diversion, and smog control, resulting in limited space for subway construction and high environmental protection requirements. When the traditional construction method breaks the construction of the underground diaphragm wall at the connection part of the subway station and the auxiliary structure, there are disadvantages such as high risk of construction operation, many personnel required for construction operation, high labor intensity, and easy to generate dust pollution. The traditional me...
