Description

Concrete pipe pile center plugging structure Technical Field The utility model relates to the technical field of building construction, in particular to a concrete pipe pile center plugging structure. Background In the existing tubular pile construction, after the tubular pile is positioned, a reinforcement cage is arranged in a tubular pile center hole, but the reinforcement cage is only inserted into the 2m depth position of the upper end of the tubular pile center hole according to design requirements, the bottom end of the reinforcement cage does not have a positioning and clamping function, the existing scheme is that the metal rod is clamped at the tubular pile opening position, but the bottom end of the reinforcement cage is also provided with an opening which can not receive concrete, so that waste is blocked by the insertion of the reinforcement cage bottom end; if the operation is not standard, the problem of concrete mortar leakage still exists because the gap exists between the outer wall of the reinforcement cage and the inner wall of the tubular pile, the blocking effect is also poor, and the problem of the exposed reinforcement cage exists at the bottom end. In addition, the reinforcement cage is not supported in the tubular pile, so that the problem of eccentricity of the reinforcement cage exists. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a concrete pipe pile center plugging structure, which solves the problems of exposure and eccentricity of the existing reinforcement cage. The concrete pipe pile central plugging structure comprises a pipe pile body which is inserted into the ground, wherein a bearing and positioning structure is arranged in the pipe pile body, a steel cage is inserted into the bearing and positioning structure, cement filling is poured between the steel cage and the pipe pile and above the bearing and positioning structure, and the top end of the steel cage is higher than the upper port of the pipe pile body.
