Abstract
The pipe-lining material includes a pipe-shaped resin absorbent material impregnated with a liquid curable resin, and a tube that covers the pipe-shaped resin absorbent material and that can be removed from the pipe-shaped resin absorbent material. The curable resin impregnated in the pipe-shaped resin absorbent material is cured in a state in which the pipe-lining material is pressed against the internal peripheral surface of the existing pipe, the tube covering the pipe-shaped resin absorbent material of the pipe-lining material is removed from the pipe-shaped resin absorbent material after the curable resin impregnated in the pipe-shaped resin absorbent material has been cured, and the surface of the pipe-shaped resin absorbent material having the cured resin is used as the internal peripheral surface of the rehabilitated existing pipe. The internal peripheral surface can be prevented from becoming rough and the coefficient of roughness of the internal peripheral surface of the rehabilitated existing pipe can be reduced because the internal peripheral surface of the existing pipe is a cured, firm resin surface.
