AI Technical Summary

Technical Problem

Existing foundation pit support structures are mostly concrete-cast, which are costly and non-reusable, cannot adapt to the inner walls of foundation pits with different inclination angles, and have high costs for both casting and demolition.

Method used

The structure adopts a detachable and reusable foundation pit support structure. It is connected to the horizontal and vertical trusses by pins, and combined with the design of hydraulic rods and sliding frames, the angle can be adjusted. The retaining plate can be detached and installed through slots and bolts, which can adapt to foundation pits of different sizes and shapes.

Benefits of technology

It enables flexible disassembly and reuse of the support structure, reduces costs, improves adaptability to foundation pits with different inclination angles, and enhances connection stability and support effect.
