AI Technical Summary
The existing precast retaining wall molds are fixed with bolts, which makes disassembly and assembly cumbersome, reducing the production efficiency and construction speed of the retaining wall.
The mold is quickly assembled and disassembled by using a sliding connection between the locking block and the limiting block, and the support components improve stability and ease of transportation.
This improved the speed of mold assembly and disassembly, as well as the efficiency of pouring, ensuring rapid construction of the protective wall and avoiding construction delays caused by cumbersome fixing procedures.
