TUBULAR CONNECTING MEMBER, MANUFACTURING METHOD THEREFOR, AND PIPE LINING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pipe lining method capable of reducing the cost by making a pipe line connect firmly to a pipe lining material and reducing the thickness of the pipe lining material. SOLUTION: This pipe lining method is constructed using a tubular connecting member 1, which comprises by welding (or sticking or needle-punching connecting) adsorbent, capable of adsorbing a grouting material 7 to the inner/ outer circumferential surfaces of a soft tubular plastic film (or a tubular woven fabric or tubular non-woven fabric) and a pipe lining material 6, which comprises by impregnating unhardened hardening resin to a tubular resin adsorbent. After inserting the tubular connecting member 1 into the pipe line 10, the tubular lining material 6 is reversed and inserted inside the tubular connecting member 1 by hydraulic pressure, the hydraulic pressure acts inside the pipe lining material 6 so as to pressurize the pipe lining material 6 toward the inside surface of the tubular connecting member 1, the hardening resin impregnating into the tubular lining material 6 is hardened, and then the grouting material 7 filling between the pipe line 10 and the tubular connecting member 1 is hardened.
