Building method for building subway station on soft land without occupying road

Abstract

The invention discloses a construction method for constructing a subway station on soft ground without occupying roads, comprising step S1: adopting an open and cut method to construct an external auxiliary structure at the station end; Leave the construction conditions of underground excavation at both ends of the terminal hall of the station; step S3: excavate the separated platform layer structure in the middle of the station; step S4: excavate the connecting passage for construction; step S5: construct the internal structure and decoration, and complete the civil works. Since the present invention adopts the above method and structure, repeated cuts and relocations and relocation procedures of municipal pipelines are avoided, the urban traffic is busy, and the public interest is maintained.

Description

technical field [0001] The invention relates to the technical field of underground structures, in particular to a construction method for constructing subway stations on soft soil without occupying roads. Background technique [0002] my country's current urban construction subway generally passes through the central urban area of ​​the city. Therefore, it is necessary to build a subway station in the central urban area of ​​the city. In my country's urban centers, the surrounding buildings (structures) are dense, and the pipelines under the roads are densely covered with heavy road traffic. Especially in international metropolises such as Shanghai, the rail transit route network has a certain scale. Lines are more restrictive. [0003] my country's Beijing, Guangzhou and other areas generally adopt the full-underground excavation method to build subway stations. The full-underground excavation method is based on the fact that the soil quality in Beijing, Guangzhou and other...

AI Technical Summary

Problems solved by technology

[0006] 1. Since municipal pipelines are generally buried under the existing roads, the use of open cut method will lead to repeated relocation of municipal pipelines, resulting in cost losses

[0007] 2. Due to the need to semi-close or fully close the road involved by the open cut method, it will cause traffic diversion or even cut off the road traffic, affecting the travel of citizens

[0008] 3. Using the open cut method may cause a large number of demolition projects
