Abstract

The invention provides a rail transit structure and a construction method thereof, and relates to the field of underground engineering. The rail transit structure comprises a station, a connecting section and a shield section, wherein the station comprises a station body and a station air shaft communicating with the station body, the station air shaft is used for lowering a shield tunneling machine, one end of the connecting section communicates with the station body and is spaced from the station air shaft, the cross section of the connecting section is larger than that of the station body,the connecting section can allow the shield tunneling machine to pass, and the shield section communicates with the end, away from the station body, of the connecting section. The rail transit structure is beneficial to reducing the engineering excavation amount and improving the economical efficiency.

Description

technical field [0001] The invention belongs to the field of underground engineering, and more specifically relates to a rail transit structure and a construction method thereof. Background technique [0002] The shield method is widely used in the construction of underground engineering. In scenarios where shield tunneling technology can be used, the shield tunneling method is often preferred for construction. A tunnel with a uniform cross-sectional size can be formed by shield tunneling. [0003] The frequency of urban rail transit is high, and the journey is relatively short. The design of the line near the subway station is relatively complicated, and it is often necessary to excavate a larger section near the subway station. Sectional tunnels that run between two subway stations are usually relatively uniform in cross-section. In the related technology, after the large-section excavation section is formed, the starting shaft of the shield machine can be excavated at ...
