Embodiment Construction

[0034] It should be noted that, in the case of no conflict, the embodiments in the application and the technical features in the embodiments can be combined with each other. Undue Limitation of This Application.

[0035] The orientation terms described in this application are only for the convenience of describing the application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a reference to this application. limits.

[0036] During the construction of the foundation pit of the subway station, the enclosure body 200 is usually constructed before excavation, and then the foundation pit support system is continuously constructed in the foundation pit while excavating from top to bottom. When digging to the bottom, start to build the subway station from the bottom up. During the construction of th...

Abstract

The invention provides a supporting component, a foundation pit supporting system and a construction method of a subway station. The supporting component is used in the foundation pit supporting system for constructing the subway station and comprises chord members and connecting pieces, wherein the two chord members are arranged up and down at intervals, the two ends of each chord member are connected to an enclosure body of the foundation pit supporting system, and the two ends of at least the upper chord member are detachably connected with the enclosure body. The connecting pieces are connected between the upper chord member and the lower chord member. According to the supporting component, the prefabricated chord members and the connecting pieces are spliced to form the supporting component, so that after construction is completed, the upper chord member can be disassembled and reused, the lower chord member can be used in a station top plate to continue to provide support for thestation top plate, and the construction difficulty is reduced.

Description

technical field [0001] The present application relates to the technical field of subway station construction, in particular to a support member, a foundation pit support system and a construction method for a subway station. Background technique [0002] During the construction of the subway station, in order to prevent the soil around the foundation pit from collapsing into the foundation pit and affecting the normal construction work of the station, it is necessary to support the foundation pit. Usually, enclosures are used for enclosure before excavation, and then support members are used to support the enclosure after excavation to prevent enclosure failure. As part of the support system in the foundation pit, the support members undertake a large amount of supporting work. [0003] In the current technology, the supporting components are usually integrally formed by pouring concrete. In this way, after the supporting work is completed, all the supporting components need...
