BRANCH TUBE LINING MATERIAL AND BRANCH TUBE LINING METHOD

摘要

PURPOSE: To provide a branch tube lining material and a method for lining a branch tube in which filler can be injected in a gap generated to a the tube without externally discharging and the tube having large deviation, breakage or bent can be effectively lined without wrinkle. CONSTITUTION: A branch tube lining material 1 mounts the collar 9 formed at one end of a filler casting tube 7 having a larger diameter than a tubular resin absorbing material 2 at the collar 3 of the material 2 having the collar 3 at one end and impregnated with curable resin, and inserts the tube 7 into the material 2. Since the filler 27 is injected in a gap between the material 2 of the material 1 and the tube 7, the external discharge of the filler 27 is effectively prevented by the tube 7. A branch tube 11 having large deviation, breakage or bent can be effectively lined without wrinkle.
