REINFORCEMENT STRUCTURE AND REINFORCEMENT METHOD FOR EXISTING PILE

PROBLEM TO BE SOLVED: To reduce the cost needed for reinforcement by reinforcing an existing pile easily in a short time.SOLUTION: A reinforcement structure comprises a concrete form 2 installed surrounding a periphery of a pile 41 and fiber-reinforced concrete 20 charged between the concrete form 2 and the pile 41. The concrete form 2 includes a concrete form member 3 formed cylindrically by being parted in an axial direction at at least one place in the circumferential direction, and joining end faces of parted parts together. The concrete form 2 need not have strength as a structural member reinforcing the pile 41, so that the trouble and time needed to install the concrete form 2 can be saved to greatly reduce the cost needed to reinforce the pile 41.
