Underground station structure with stop line in urban rail transit project

Abstract

The invention provides an underground station structure with a stop line in an urban rail transit project. The structure is arranged on an underground station with a stop line in an urban rail transit project. The structure comprises two groups of symmetrical three-way turnouts, connection rails, two groups of buffer stops, four groups of single-way turnouts and platforms. The two groups of symmetrical three-way turnouts are connected with the two groups of buffer stops through the connection rails, to form a symmetric three-way turnout through stop line, and then connected with the four groups of single-way turnouts paved on right and left main tracks through the connection rails, to form the underground station structure with the stop line together with the platforms. The underground station structure has the effects that the total length of the underground station can be shortened by 50-60 meters approximately, the station which is excavated is partially changed into a running tunnel of which the construction adopts a shield method, thus the demolition of structures, changing of municipal pipelines and scale of traffic reconciliation caused by the project are reduced, the project investment is lowered, the construction difficulty and risk are lowered, and the influence on the urban environment due to implementation of the project is decreased.

Description

technical field [0001] The invention relates to an underground station structure with a stop line in an urban rail transit project. Background technique [0002] Urban rail transit projects have developed rapidly in my country in recent years, and are mainly used for large-capacity urban passenger transportation, which is an effective means to improve traffic congestion in large cities. [0003] The problem of traffic congestion in my country's big cities is becoming more and more serious, and urban rail transit is being built one after another. For example, the rail transit network in Beijing, Shanghai, Guangzhou, Shenzhen and other cities has basically been completed. Nanjing, Tianjin, Shenyang and other cities have begun to take shape. Some medium-sized cities such as Qingdao, Ningbo, Suzhou, Xiamen, etc. are actively starting construction. Because each city independently raises funds, builds and manages independently, and lacks systematic research and development and uni...

AI Technical Summary

Problems solved by technology

[0004] Underground stations with parking lines in urban rail transit projects are necessary facilities for operation, and are also difficult points and control nodes in the construction of a subway line. Generally, underground stations with parking lines are more than 500 meters long. In order to attract passenger flow, subway stations are mostly located in crowded areas. In the prosperous urban area, construction excavation during project construction will inevitably lead to large-scale demolition of structures, relocation of municipal pipelines, traffic diversion, etc., which will greatly interfere with the urban environment and the risk is extremely high
