Supporting system at transfer node of urban rail transit transfer station and construction method

Abstract

The invention provides a supporting system at a transfer node of an urban rail transit transfer station and a construction method of the supporting system at the transfer node of the urban rail transit transfer station. The supporting system at the transfer node of the urban rail transit transfer station comprises an outer ring support, an inner ring support and an inner and outer ring connectingcomponent, wherein the outer ring support is arranged at the joint of multiple rail transit lines, the inner ring support and the outer ring support are concentrically arranged, and the inner ring support is a large ring beam inner ring support to replace a diagonal bracing system to improve the overall rigidity of the supporting system. A multi-ring stress system is reasonable in structural layout, the overall rigidity is high, the deformation control effect is good, the compression resistance of concrete is fully utilized, the water and soil pressure on the outer side of the supporting structure is converted into the compression bearing capacity of supporting components; and meanwhile the supporting structure has the advantages that the construction efficiency is high, the construction period is saved, no diagonal bracing structure is arranged on inner side of the inner ring support, and the earthwork unearthing space is increased to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of rail transit construction, and more specifically relates to a support system at a transfer node of an urban rail transit transfer station and a construction method for the support system at a transfer node of an urban rail transit transfer station. Background technique [0002] With the rapid development of urban rail transit nowadays, rail transit lines are developing into a network, double-line and multi-line transfer stations are becoming more and more common, and the functions of transfer stations are diverse. The conditions are complicated. The standard subway station has a rectangular structure, and its stress and design are simple, but the design of transfer nodes is a major and difficult point. At present, there is no unified, standard, and effective construction method. [0003] At present, the traditional subway support method adopts the support system of divided pits. During the construction w...
