AI Technical Summary
The existing foundation pit guardrails used in construction projects are of a single, integrated structure, which means that when a part is damaged, the entire structure needs to be replaced, as it cannot be disassembled for maintenance.
The design employs a support frame, partitions, and assembly structure. By utilizing a combination of threaded connections, limit blocks, and screw nuts, the support frame and partitions can be disassembled and assembled. The threaded connections and limit structures are used to position and limit each component.
The design enables the pit guardrail to be disassembled and assembled, avoiding the need for complete replacement due to partial damage, and improving maintenance efficiency and material utilization.
