Embodiment Construction

[0031] Such as Figure 1 to Figure 4 Shown, be the subway station construction method of a kind of bridge of the present invention, station joint construction mode, comprise the following steps successively:

[0032] Among them, the stratum soil at the location where the subway station is built is distributed from top to bottom as miscellaneous filling soil layer A, plain filling soil layer B, loose pebble layer C, medium-dense pebble layer D, the first medium sand layer E, and the first dense The pebble layer F, the second middle sand layer G and the second dense pebble layer H. Z in the figure represents the ground.

[0033] a. Determine the construction location of the bridge piles that double as the structural columns of the subway station. The design of the subway station and the bridge is connected, and the joint position between the bridge support pile and the subway station structural column is determined (that is, the construction position of the bridge pile is dete...

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...
