Bored pile head and pile head breaking method thereof

Abstract

The invention discloses a bored pile head and a pile head breaking method thereof. The bored pile head comprises a pile head, the top end of the pile head is arranged in a bearing platform, a plain concrete cushion layer is built on the bottom end of the bearing platform, a pile body is arranged in the pile head, longitudinal main ribs are arranged in the pile head at two sides, longitudinal main rib PVC sleeves sleeve the longitudinal main ribs, a horizontal PVC sleeve is arranged in the elevation position of the pile head, the diameter of each longitudinal main rib PVC sleeve is slightly larger than that of each longitudinal main rib, and the diameter of the horizontal PVC sleeve is equal to the thickness of a main rib protecting layer. The bored pile head has the beneficial effects that steel bars are isolated from concrete by the PVC sleeves, and the pile head is cut off by transverse force of the tip of a steel wedge. By using the method, the steel bars of the pile head can be protected, the labor intensity during construction and the construction cost are reduced, the pile head breaking efficiency is improved, the problem of damage to the pile body and the steel bars is effectively solved, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of civil construction, and relates to a pile head of a bored cast-in-place pile and a method for removing the pile head. Background technique [0002] In the current domestic construction industry, in the process of removing the bored pile head, the conventional construction method is extremely cumbersome, and the labor intensity is high, the construction efficiency is low, and there is certain damage to the concrete and steel bars of the pile body, which is not conducive to the control of project quality. Contents of the invention [0003] The invention isolates the connection between the steel bar and the concrete by using the PVC pipe, and utilizes the lateral force of the pointed part of the steel wedge to cut off the pile head. This method can protect the pile head reinforcement, reduce the labor intensity and construction cost during construction, improve the removal efficiency of the pile head, effectively so...
