Problems solved by technology

The support technology of traditional retaining piles combined with internal support will inevitably bring adverse effects to the main structure of the subway station. For example, the support needs to be erected on the main structure of the subway station.
When removing the main retaining piles at the junction of the main structure of the subway station and the auxiliary structure, it will lead to the conversion of the process, affect the construction efficiency, and cause the construction to be blocked and the construction quality to be damaged

Abstract

The invention discloses an accessory structure foundation pit supporting structure system parallel to a subway station main body structure, which comprises main body structure fender posts (2) arranged on the periphery of the subway station main body structure (1), and is characterized in that front-row piles (4) of accessory foundation pit double-row piles and rear-row piles (5) of the accessory foundation pit double-row piles are arranged parallel to the subway station main body structure (1); front-row piles (4) of the auxiliary foundation pit double-row piles are connected through top beams (6) of the auxiliary foundation pit front-row piles, and rear-row piles (5) of the auxiliary foundation pit double-row piles are connected through top beams (7) of the auxiliary foundation pit rear-row piles. Auxiliary foundation pit fender posts (9) are arranged at the two ends of a top beam (6) of the auxiliary foundation pit front-row piles respectively, and an auxiliary foundation pit top beam (10) is poured to be connected with the main body structure fender posts (2).

Description

technical field [0001] The invention belongs to the technical field of foundation pit support for underground engineering, and in particular relates to a foundation pit support structure system with an auxiliary structure parallel to the main structure of a subway station. Background technique [0002] With the continuous development of the national economy and the continuous acceleration of the urbanization process in my country, the development and utilization of urban rail transit has attracted the attention of relevant units. As urban rail transit has spread all over the main streets of first- and second-tier cities, more and more subway stations are planned to be constructed on the non-arterial streets of the city, especially the streets of the old city, where the roads are narrow and the space is small. In order to meet the basic functions of the station, many auxiliary structures and the main structure of the subway station are arranged in plan. In order to meet the ...
