Subway station construction method

Abstract

A subway station construction method belongs to underground build technology field. The method includes subway station enclosing and protection, the construction of load carrying structure-underground continue wall, executing deep layer high-pressure grouting for the ground base soil layer in the continue wall, casting-in-place ferroconcrete to the top of the continue wall to form the top plate of the subway station, casting-in-place ferroconcrete counterfort moving beam or mounting prefabricated counterfort moving beam on the low side of the first layer floor plate under the top plate and the periphery of the continue wall and proceeding the construction of the floor plate of the layer, proceeding the following layer construction by the passages among layers, constructing the reverse arched bottom plate. The invention adopts inverse construct method, the construction quantity is small, the construction efficiency is high and the construction quality is good.

Description

technical field [0001] The invention belongs to the technical field of underground construction, in particular to a method for constructing a subway station. Background technique [0002] Underground space is a precious resource for human beings, and large-scale development of underground space is a natural product of human social and economic development to a certain stage. With the rapid development of my country's social economy, the comprehensive national strength is increasing, which has laid an economic and technical foundation for the development of underground space. In addition, dozens of large cities and megacities across the country have encountered more and more problems in environmental protection, transportation, land resources, and living space after more than half a century of continuous development, which has become a bottleneck for the sustainable development of modern cities. Scientific, orderly, reasonable and efficient development of underground space h...

Problems solved by technology

Using the traditional method mentioned above, once the earthwork in the wall is dug to the bottom, a large number of supporting steel pipes are used in the wall when excavating the earthwork, and the equipment consumption is large; the horizontal and vertical surfaces are intersected and interfere with each other; the working conditions are bad, the safety is poor, the work efficiency is low, and the construction period is long.
