Construction method and building structure of co-construction of subways and city underground comprehensive pipe galleries

Abstract

The invention provides a building structure of co-construction of subways and city underground comprehensive pipe galleries. The building structure comprises section shield tunnels. An intermediate partitioning member used for dividing space in each section shield tunnel into two areas in the axial direction, wherein one of the areas serves as a subway travelling cabin, and the other area serves as pipe gallery cabins arranged continuously or at intervals in the axial direction. The invention further provides a building method of co-construction of the subways and the city underground comprehensive pipe galleries. By means of the structure and the method, the problem of building of common path sections of the large city center urban area comprehensive pipe galleries and the subways is solved, underground space is saved, construction disturbance is reduced, and the construction risk is lowered.

Description

technical field [0001] The invention relates to the field of co-construction of a pipe gallery and a subway, in particular to a construction method and a building structure for the co-construction of a subway cabin and an urban underground comprehensive pipe gallery. Background technique [0002] At this stage, urban comprehensive pipe corridors are generally constructed by open cut or shield method. For subway tunnels with the same route, they are multi-line parallel. Due to the influence of road width and subway station burial depth, etc., the tunnel longitudinal section design is more complicated, or up and down, left and right Stacked lines, or multi-line parallel arrangement on the same floor, require a large underground space. In the area of ​​the station, the subsidiary entrance and exit of the subway and the wind pavilion must be passed under, which brings certain risks to the construction and has high requirements for the construction organization. [0003] Based o...

AI Technical Summary

Problems solved by technology

[0002] At this stage, urban comprehensive pipe corridors are generally constructed by open-cut or shield methods. For subway tunnels on the same route, they are multi-line parallel. Due to the influence of road width and subway station burial depth, the tunnel longitudinal section design is more complicated, or vertical, vertical, horizontal Stacked lines, or multi-line parallel arrangement on the same floor, requires a large underground space

In the scope of the station, the subsidiary entrance and exit of the subway and the wind pavilion must be passed under, which brings certain risks to the construction and has high requirements for the construction organization.
