The invention provides a pile body reinforcement cage and a concrete device for guaranteeing the thickness of a protecting layer of the pile body reinforcement cage. The concrete device is applied tothe pile body reinforcement cage and comprises a concrete body and a connecting piece, wherein the concrete body is circular and has a preset thickness, and the concrete body is used for sleeving thereinforcement cage; the first end of the connecting piece is arranged in the concrete body, and the second end of the connecting piece is arranged outside the concrete body and used for being connected with the reinforcement cage. By means of the concrete device, the distance deviation between the reinforcement cage sleeved with the concrete body and a pile foundation hole in the axial direction of the pile foundation hole can be effectively reduced, namely the axial position deviation of the reinforcement cage in the pile foundation hole is reduced, and therefore it is ensured that the reinforcement cage is kept in a vertical state in the pile foundation hole; moreover, the circular concrete body directly serves as the protecting layer of the reinforcement cage, so that the uniformity ofthe thickness of the protecting layer of the reinforcement cage is greatly improved, and the placing efficiency of the reinforcement cage can be improved.
Description
technical field [0001] The invention relates to the technical field of pile foundation engineering, in particular to a reinforcement cage for a pile body and a concrete device for ensuring the thickness of the protective layer of the reinforcement cage for the pile body. Background technique [0002] At present, during the construction of cast-in-situ piles, the reinforcement cage is first made, then the reinforcement cage is hoisted, and then the reinforcement cage is placed in the pile foundation hole. However, the reinforcement cage is prone to local deflection and deformation during hoisting, and during the lowering process, due to the distance between the reinforcement cage and the inner wall of the pile foundation hole, poor control of the verticality of the reinforcement cage is likely to occur, resulting in the reinforcement cage being in the pile. The inclination of the foundation hole makes the axial position deviation of the reinforcement cage unable to meet the s...
