Metro station with double-hole double-layer ejector pipe space combination

Abstract

The invention discloses a metro station with double-hole double-layer ejector pipe space combination, and relates to the technical field of metro stations. The metro station comprises a first ejectorpipe double-layer tunnel and a second ejector pipe double-layer tunnel which are symmetrically arranged. The first ejector pipe double-layer tunnel communicates with the second ejector pipe double-layer tunnel through a transverse connecting channel. The outer sides of the tops of the first ejector pipe double-layer tunnel and the second ejector pipe double-layer tunnel are each provided with an inlet and outlet channel. Inner spaces of the first ejector pipe double-layer tunnel and the second ejector pipe double-layer tunnel are each divided into an upper layer space and a lower layer space through structural plates. Each upper layer space is internally provided with a platform and an escalator. A first line is arranged in the lower layer space of the first ejector pipe double-layer tunnel, and a second line is arranged in the lower layer space of the second ejector pipe double-layer tunnel. The metro station can effectively meet the station process and function, meanwhile, the project practicability is high, the construction risk can be reduced, pipeline relocation is reduced, traffic reconciliation is optimized, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of subway stations, in particular to a subway station with space combination of double-hole and double-layer pipe jacking. Background technique [0002] In densely built urban areas, there are many ground and underground structures and pipelines, and the road traffic is heavy. There are construction problems and contradictions such as difficult implementation conditions, high construction risks, uncontrollable construction period, and high preliminary engineering costs in the construction of stations or sections by open-cut method, combination of open and dark, and underground excavation methods. It is a better way to solve the problem of subway construction by using the pipe jacking method in the subway construction in the central area of ​​the city. The current pipe jacking space is small, and a single space cannot meet the functional and technological requirements of the subway station. Oversized pipe jac...

Problems solved by technology

There are construction problems and contradictions in the construction of stations or sections by open-cut method, combination of open and dark, and underground excavation methods, such as difficult implementation conditions, high construction risks, uncontrollable construction period, and high early-stage engineering costs.

It is a better way to solve the problem of subway construction by using the pipe jacking method in the subway construction in the central area of ​​the city. The current pipe jacking space is small, and a single space cannot meet the functional and technological requirements of the subway station. Oversized pipe jacking still has equipment manufacturing, On-site implementation and other issues, how to realize the function of the subway station by combining the implementable pipe jacking space is an urgent problem to be solved in the current subway construction
