PROBLEM TO BE SOLVED: To provide a pile head reinforcing structure which is simple, economical, and good in workability. SOLUTION: A pile head of a pile body 1 has mounted thereon reinforcements 3 with couplers and a cage 2. Each reinforcement 3 with the coupler is a member consisting of a reinforcement element 5 and the coupler 4 fitted on the same, and the reinforcement element 5 is arranged along an axial direction of the pile body 1 with the other end thereof protruded from the pile head, while part of an outer peripheral surface of the coupler 4 is fixed to an inner peripheral surface of a steel pipe 1a. The cage 2 is formed of a plurality of vertical reinforcements 2a and a plurality of horizontal reinforcements 2b connecting the vertical reinforcements 2a together, and its lower half body is inserted into a hollow portion of the steel pipe 1a such that an upper half portions of the vertical reinforcements 2a are protruded from the pile head. The reinforcements and the cage are embedded in a hardener 6 filled in the hollow portion of the steel pipe 1a to form the pile head reinforcing structure. According to the pile head reinforcing structure, the vertical reinforcements 2a of the cage 2 and the reinforcement elements 5 of the reinforcements 3 with the couplers are protruded from a pile head surface of the pile body 1, and these reinforcements are embedded in a foundation member 8 to function as an anchor member 7.
