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

The invention relates to a construction method for deep foundation pit support and reinforcement. The deep foundation pit support and reinforcement construction method adopts the following deep foundation pit steel mesh laying device. The deep foundation pit steel mesh laying device includes an upper support plate, a connecting rod, and a guide plate , placement frame and limit mechanism, the quantity of the upper support plate is two, and one end of the upper support plate is provided with a plunger; the deep foundation pit steel mesh laying device is used to support and reinforce the deep foundation pit slope, It includes the following steps: S1, slope trimming; S2, steel bar anchoring; S3, steel mesh roll placement; S4, steel mesh laying. The present invention can solve the problems existing in laying the steel mesh manually: when the foundation pit is deep, it is inconvenient to manually lay the steel mesh; The stencil cannot be laid smoothly, and the stencil rolls will be wrinkled when laid and the stencil cannot be straightened, which makes the laying effect of the stencil poor and other problems.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for deep foundation pit support and reinforcement. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment. The main forms of foundation pit support are: 1. Pile row support, pile support, pile anchor, pile row cantilever; 2. Underground diaphragm wall support, ground connection wall + support; 3. Cement retaining wall; 4. Spray anchor support and so on. [0003] The most commonly used method of reinforcing the slope of the foundation pit is spray anchoring. When the slope of the foundation pit is sprayed and anchored, it is first necessary to anchor the steel bars on the slope of the founda...
