[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A quick hoisting component for retaining wall formwork of the utility model includes a foundation platform, vertical steel pipes, diagonal bracing steel pipes, steel bar hooks and chain hoists. Multiple vertical steel pipes are symmetrically arranged on the rectangular foundation platform. The vertical steel pipes located at the short sides of the rectangle are supported and fixed by a triangular force-bearing structure formed by cross-laid diagonal bracing steel pipes. The vertical steel pipes located at the long sides of the rectangle are supported and fixed by a scissor-shaped force-bearing structure formed by cross-laid diagonal bracing steel pipes. Four steel bar hooks are respectively installed at the tops of the vertical steel pipes located at the four corners of the rectangle. The chain hoist is installed on the steel bar hooks, and the hook end of the chain hoist is connected to the top of the steel formwork. The chain hoist drives the steel formwork to rise from the ground to a specified height.

[0008] Preferably, a plurality of PVC pipe holes are pre-embedded on the foundation platform, and the bottom ends of the vertical steel pipes are inserted into the PVC pipe holes.

[0009] Preferably, the vertical steel pipes and the diagonal bracing steel pipes are tightly connected by rotary fasteners.

[0010] Preferably, the hook end of the chain hoist is connected to a lifting ring arranged at the top of the steel formwork.

[0011] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0012] The utility model has a simple structure and is convenient to use. It can be quickly assembled and installed to meet the construction requirements on site, and has higher convenience. After the steel formwork of the retaining wall is hoisted, it can be quickly disassembled, and the disassembled components can be reused. It occupies a small area and is convenient to carry. It can quickly lift the height of the steel formwork without using large hoisting machinery, effectively improving the construction efficiency while reducing the construction cost.
