BRANCH PIPE LINING MATERIAL, PRODUCING METHOD THEREOF, AND BRANCH PIPE LINING METHOD

摘要

PURPOSE: A branch pipe lining material, a manufacturing method thereof and a branch pipe lining method thereof are provided to perform the high quality of branch pipe lining by improve the connection between the lining materials of a main pipe and a branch pipe by inserting a branch pipe lining material from a main pipe with a completed lining when a branch lining. CONSTITUTION: A branch pipe lining material(100) includes resin sheets(103,104) and a resin absorber(102). The resin sheet is arranged in the side going toward the branch tube of a flange(101). The resin sheet is composed of a thermoplastic resins(113a,115a) possible to be thermally welded with a main lining material. The resin absorber having a ring shape is arranged between the resin sheet and the flange absorber. The resin sheet is thermally fused with the resin absorber. The flange and the resin absorber are impregnated respectively with thermosetting resin. The flange and the resin absorber are combined by solidifying the thermosetting resin.
