Lateral pipe lining material and lateral pipe lining method
Abstract:
A tubular lateral pipe lining material is configured to be inserted into a lateral pipe which intersects with a main pipe in order to repair the lateral pipe. The tubular lateral pipe lining material has a flexible tubular resin-absorbing material impregnated with an uncured curable liquid resin. The tubular resin-absorbing material has one end that is folded back. A flange member, over which the folded-back end of the tubular resin-absorbing material is pressed, is made of a thermoplastic resin. An adhesive is applied over the flange member and the folded-back end of the tubular-absorbing material to bond the tubular resin-absorbing material to the flange member.
