Embodiment 2

[0062] Embodiment 2, the difference from Embodiment 1 is that the prefabricated track foundation 3, the prefabricated platform slab 5, the lower wall of the platform slab 6, the prefabricated rail top air duct 4 and the segment connection support system are all connected by bolts, Further improve the quality of the working environment and reduce the construction period. And the bolt connection is not only convenient for installation, but also convenient for disassembly and replacement. The prefabricated platform slab 5 and the prefabricated rail top air duct 4 can adopt either steel structure or prefabricated concrete structure. Holes can be opened above the prefabricated platform slab 5 and the prefabricated rail top air duct 4 to facilitate the insertion or ventilation of pipelines.

Embodiment 3

[0063] Embodiment 3, its difference with embodiment 1 is, as Figure 13 As shown, the one-piece structural beam member includes " "Type component 24, the longitudinal section of this component perpendicular to the direction of tunnel excavation is " "Type. Specifically, the upper end of the column passes through the installation and disassembly section 7 and " "Type member 24 is connected. The lower end of the column is connected with " "Type component bolt connection; the two ends of the installation and disassembly section 7 are connected with the column and the " "Type members 24 are all bolted.

[0064] A kind of construction method of described prefabricated subway station, comprises the steps:

[0065] S1. Use the triple-circle roadheader to excavate, assemble the triple-circle subway station segments while excavating, and assemble the segment connection support system, wherein the segments are assembled piece by piece from bottom to top when assembling, and the...

Abstract

The invention provides an assembly type subway station and a construction method thereof, the assembly type subway station comprises a duct piece connecting and supporting system, the station supporting system adopts mechanical method underground excavation construction, and the duct piece connecting and supporting system comprises an assembly type supporting structure formed by assembling a plurality of prefabricated parts and a steel-concrete structure filled on the assembly type supporting structure; the prefabricated track foundation and the prefabricated platform plate are assembled and connected in the triple circular station. According to the construction method, the highly-assembled triple-circle subway station is constructed through the prefabricated parts and the bolt connection between the prefabricated parts, so that the subway station realizes component standardization and high assembly, basically realizes complete factory prefabrication of the components and on-site splicing construction, reduces manual wet operation, improves the quality of the operation environment, and shortens the construction period; according to the prefabricated subway station, mechanical underground excavation construction is adopted underground, and the influence on the life of urban residents is reduced.

Description

technical field [0001] The invention relates to the technical field of subways, in particular to an assembled subway station and a construction method thereof. Background technique [0002] With the great development of domestic subway construction, there are various structural forms of subway stations. In recent years, prefabricated subway stations have developed rapidly in China, and pilot projects of prefabricated subway stations have been carried out in many places, but only on the basis of open-cut stations, the cast-in-place operation has been moved to the factory It is prefabricated and then transported to the station for assembly. The non-underground assembled subway station has no reduced impact on the surface environment, and the construction period has not been greatly reduced. [0003] The mechanical method has been widely used in the subway. It is quite common to use the shield tunneling method to construct subway interval tunnels, and the pipe jacking method t...
