Construction method of subway station in bridge and station joint construction mode

Abstract

The invention provides a method for constructing a subway station in a bridge-station joint construction mode. The construction method first builds bridge piles that double as structural columns of the subway station, and then builds a bridge on the bridge piles; then starts to build the roof of the subway station and excavate the foundation pit , and finally build the base plate of the subway station, the retaining piles around the foundation pit and other structures. The invention ensures that during the whole construction process, the construction site occupies a small area and has little impact on ground traffic; the force on the four walls of the entire subway station is stable in the later stage, and the force does not produce huge changes, thereby improving the stability and safety of the subway station.

Description

technical field [0001] The invention relates to a method for constructing a subway station, in particular to a method for constructing a subway station in a bridge-station joint construction mode. Background technique [0002] With the rapid development of cities today, traffic problems are becoming more and more tense. With the acceleration of urbanization, major cities in my country have begun to build subways on a large scale. As we all know, subway stations are usually arranged across road intersections to attract more passengers. At the same time, major cities In order to alleviate the ground traffic on the section where the subway is located, cross bridges are gradually built at the same intersection, which often leads to the connection between the subway station and the bridge structure, or even the situation where the planes of the two completely overlap. At present, the usual treatment method is to first build the subway station underground, and the structural column...

AI Technical Summary

Problems solved by technology

Such a construction method has a great impact on the traffic of the section where the subway station is located and lasts for a long time, which is not conducive to the travel of surrounding residents; for the structure of the subway station, the force on the four walls of the subway station changes greatly in the later stage, and the roof and floor of the subway station are both Need special treatment, increase the difficulty, cost and time of construction
