REINFORCEMENT STRUCTURE OF PILE HEAD

摘要

PROBLEM TO BE SOLVED: To provide a reinforcement structure of a pile head, capable of improving the pile proof stress of a new pile head made by cutting off a precast pile and being applied to a semi-rigid bonding system.SOLUTION: A reinforcement structure of a pile head comprises: an annular reinforcement plate 5 arranged on an upper end face of a new pile head 2 made by cutting off a precast pile, and having an inner peripheral part 5a having an inner diameter smaller than that of the pile; a plurality of reinforcement rods 7 provided at intervals along a circumferential direction of the inner peripheral part 5a of the reinforcement plate 5 and suspended so as to extend in a hollow part 6 inside the pile head; and infilling concrete 8 filled in the hollow part 6 inside the pile head so that the reinforcement rods 7 are embedded.
