BRANCH PIPE LINING MATERIAL AND PIPE LINING TECHNIQUE

Japanese Patent JPH10278115

A

To provide a branch pipe lining material capable of mounting a hole protective member to a peripheral edge of a branch pipe opening at the same time that the lining of a branch pipe is finished, irrespective of a bore of a main pipe.

This branch pipe lining material 1 is constituted to have each flange portion 1B formed at one end of a hardening resin-impregnated portion 1A composed of a tubular resin-adsorption material impregnated with an uncured liquid hardening resin. In this case, a cylindrical hole protective member 3 for protecting an inner peripheral face of the hardening resin-impregnated portion 1A, which is adjacent to the flange portion 1B, is mounted to the flange portion 1B. Accordingly, since the hole protective member 3 is mounted in advance to the flange portion 1B of the branch pipe lining material 1, the hole protective member 3 is to be fitted to a peripheral edge of a branch pipe opening at the same time that the lining of the branch pipe, for which the branch pipe lining material 1 is used, is finished, irrespective of a boar of a main pipe, and the damage of the branch pipe lining material, which is caused by a cutter at the time of hole-making work, can be reliably prevented by the hole protective member 3.
