Abstract

The invention relates to a high-strength foundation pit supporting structure, and relates to the field of foundation pit supporting. The high-strength foundation pit supporting structure comprises a supporting frame abutting against the side wall of a foundation pit, wherein a plurality of vertical fixing rods are arranged on the side, away from the side wall of the foundation pit, of the supporting frame in an abutting mode in the horizontal direction, the bottom ends of the fixing rods are inserted below the foundation pit, a steel wire mesh is fixedly arranged between every two adjacent fixing rods, and a concrete layer is poured between the steel wire meshes and the side wall of the foundation pit. The high-strength foundation pit supporting structure has the effects that the supporting strength of the foundation pit is improved, and the possibility of collapse of the side wall of the foundation pit is reduced.

Description

technical field [0001] The application relates to the field of foundation pit support, in particular to a high-strength foundation pit support structure. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. When the excavation of the foundation pit is not deep, the method of setting the side slope can be used to stabilize the soil slope; when the excavation of the foundation pit is deep and there are buildings nearby, it is necessary to support the side wall of the foundation pit. [0003] The existing Chinese patent whose publication number is CN204898683U can be referred to, which discloses a high-strength foundation pit support structure, including an anchor net arranged on the side slope of the foundation pit, the top of the foundation pit and the lower end of the side slope. A row of first prestressed pipe piles and second prestressed pipe piles are buried res...
