AI Technical Summary
The safety protection effect of the existing reserved holes is unstable and easy to be kicked open. The later sealing process is complicated and there are problems such as leakage and cracks, which affects the construction safety and quality.
The inner peripheral wall of the reserved hole is designed to have a bearing surface that gradually shrinks from top to bottom. There are multiple holes on the bearing surface. The insert rod inserted into the hole is closed by using a protective member to insert the insert rod. The protection includes a protective plate and a U-shaped rib or prefabricated block and a steel mesh. The stability is enhanced by the insert rod and fixed with structural glue when necessary.
It improves the stability of the protective parts, prevents them from being kicked away, simplifies the sealing process, improves construction efficiency and safety, reduces safety hazards, and enhances construction quality and economic benefits.
