BRANCH PIPE LINER BAG AND PIPE LINING METHOD |
摘要 |
A branch pipe liner bag immune to damage caused by a cutter is provided. In the branch pipe liner bag having a flange formed at an end of a hardenable resin impregnated bag which comprises a tubular resin-absorbent material impregnated with an unhardened liquid hardenable resin, a cylindrical anti-piercing protector 3 is mounted on the flange. According to a pipe lining method implemented using the branch pipe liner bag according to the present invention, the branch pipe liner bag adjacent to the flange is, after a branch pipe is lined, protected by the anti-piercing protector, and therefore, in a piercing work thereafter of a main pipe liner bag, the branch pipe liner bag is immune from damage caused by a cutter, thereby eliminating a problem such as infiltration of the underground water into the main pipe from a damaged portion.
