Deep foundation pit supporting and reinforcing construction method

Abstract

The invention relates to a deep foundation pit supporting and reinforcing construction method. The deep foundation pit supporting and reinforcing construction method adopts a deep foundation pit steel mesh laying device, the deep foundation pit steel mesh laying device comprises upper supporting plates, a connecting rod, guide plates, a placing frame and a limiting mechanism, wherein the two upper supporting plates are arranged, and one end of each upper supporting plate is provided with an inserting rod. The supporting and reinforcing construction method for a side slope of a deep foundation pit through the deep foundation pit steel mesh laying device comprises the following steps of S1, trimming the side slope; S2, anchoring steel bars; S3, placing a steel mesh roll; and S4, laying s steel mesh. The deep foundation pit supporting and reinforcing construction method can solve the problems, exiting during manual steel mesh laying, that when the foundation pit is deep, manual laying of the steel mesh is inconvenient, when the steel mesh is unwound from the upper end of the side slope, the steel mesh roll can be clamped on the steel bars, and accordingly, the steel mesh cannot be smoothly laid; and wrinkles can be generated when the steel mesh roll is laid, the steel mesh cannot be straightened, and accordingly, the laying effect of the steel mesh is poor.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a deep foundation pit support and reinforcement construction method. Background technique [0002] Foundation pit support refers to the support, reinforcement and protection measures adopted for the side walls of the foundation pit and the surrounding environment in order to ensure the safety of the construction of the underground structure and the surrounding environment of the foundation pit. The main forms of foundation pit support are: ⒈ row pile support, pile support, pile anchor, row pile cantilever; ⒉ underground diaphragm wall support, ground connection wall + support; ⒊ cement retaining wall; 4. Shotcrete anchor support and so on. [0003] The most commonly used method for the reinforcement of the foundation pit slope is the method of shotcrete. When the shotcrete construction is carried out on the side slope of the foundation pit, it is first necessary to...

AI Technical Summary

Problems solved by technology

[0004] When the foundation pit is deep, it is inconvenient to manually lay the steel mesh, and there will be certain safety hazards in manual laying. When the steel mesh is unwound from the upper end of the slope, the steel mesh roll will be stuck on the steel bar, causing the steel mesh to fail to move smoothly. When laying, the steel mesh roll will produce wrinkles and the steel mesh cannot be straightened, which makes the laying effect of the steel mesh poor, and the steel mesh needs to be manually pushed when it is clamped with the steel bars on the slope
