Description

TECHNICAL FIELD

If the local force of the plane retaining board is too large, it is easy to cause the deformation or damage of the plane retaining board. The existing square piles have a rectangular cross-section. The fixing effect of the existing square piles on the plane retaining board is not ideal. Once the plane retaining board is displaced, the stability of the entire retaining wall structure will be seriously threatened, and then safety accidents such as soil collapse will occur. SUMMARY
