AI Technical Summary

Technical Problem

Traditional precast concrete pipe pile caps are prone to cracking due to stress concentration during long-term hammering by a pile driver. Especially when subjected to vertical loads or horizontal seismic forces, the cracks extend into the pile body, affecting the overall bearing capacity and the stability of the building foundation.

Method used

The protective components include a protective cover, threaded reinforcing ribs, buffer components, positioning components, and drainage channels, which enhance the impact resistance and stability of the pile cap by dispersing the hammer force, buffering energy, fixing the position, and draining water.

Benefits of technology

It effectively prevents cracks in the pile cap due to stress concentration, enhances the vertical bearing capacity and overturning resistance, and improves the overall stability and safety of the pile foundation.

Abstract

The utility model relates to pile cap technical field discloses a kind of precast concrete pipe pile pile cap, including pile cap, the pile cap outside is provided with protection assembly, the protection assembly includes protective cover, the protective cover slidingly connects in the outer wall of the pile cap, the protective cover top is fixedly connected with thread reinforcing bar, the protective cover inner wall is provided with connecting ring, the connecting ring is located at the top of the pile cap, the connecting ring outer wall is provided with buffer assembly, the pile cap outer wall is provided with positioning assembly.In the utility model, the hammering force is dispersed by the thread reinforcing bar, and the buffer assembly is used to slow down the hammering force, so as to achieve the protection effect of the product. The problem of cracks caused by stress concentration during the long-term hammering process of the traditional product by the pile hammering machine is solved. Especially when bearing vertical load or horizontal seismic force, the cracks will expand to the pile body, affecting the overall carrying capacity. The vertical carrying capacity of the product is enhanced.
