Abstract

The invention relates to the technical field of constructional engineering, and particularly relates to a foundation pit supporting structure. The foundation pit supporting structure comprises a plurality of auxiliary fender posts and a plurality of steel supports, wherein the auxiliary fender posts are arranged on the sides, away from a main structure, of auxiliary foundation pits and are opposite to main fender posts; and the steel supports are supported between the auxiliary fender posts and a main second lining lintel of the main structure. According to the foundation pit supporting structure, the second lining lintel of the main structure is adopted as an internal fulcrum of the steel supports, force transmission balance of the steel supports is guaranteed, and the erection problem ofthe steel supports is well solved. The foundation pit supporting structure has the advantages of being clear in force transmission, convenient to construct, short in construction period, low in manufacturing cost and small in influence on the surrounding environment.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to a foundation pit support structure. Background technique [0002] In urban rail transit projects, the excavation station foundation pit usually adopts the form of enclosure pile + steel support support structure. When the foundation pit is deep, it is necessary to set up multiple steel supports. On the retaining piles, so as to ensure the force balance of the foundation pit. For the auxiliary foundation pit, generally the retaining piles between the main body of the station and the auxiliary structure are dug as they are dug. The auxiliary foundation pit is affected by the surrounding environment. If there are nearby buildings (structures), if the layout of the foundation pit is parallel to the length direction of the station and becomes narrow and long, there will be problems that the steel support cannot be erected, and the layout of the steel suppor...
