Subway station building method using bridge and station combined building mode

Abstract

The invention provides a subway station building method using a bridge and station combined building mode. The subway station building method using the bridge and station combined building mode comprises the following steps of first building a bridge pier which is also used as a subway station structural column; building a bridge on the bridge pier; and then beginning to build a subway station top slab and excavate a foundation pit; and finally, building a subway station bottom slab, a foundation pit fender post and the rest structures. According to the invention, small area occupied by a construction site and small influence on ground transportation in the whole construction process are ensured; and four walls of the whole subway station are stably stressed in the later stage, the stress cannot make a big difference, and the stability and safety of the subway station are enhanced.

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
