Abstract

PURPOSE: To simply repair the broken position of a pipe in a short time by pressing the porous section of a repairing sheet impregnated with a thermosetting synthetic resin adhesive to a pipe wall to be repaired, then heating a planar heating element, and hardening the synthetic resin.
CONSTITUTION: Flexible electric wires are woven on both side edge sections of a woven fabric, a conducting paint is coated, and a planar heating element stuck with vinyl chloride films on both faces is formed. A mat-shaped nonwoven fabric made of glass fibers and polyester fibers is laminated and stuck on one face with a synthetic rubber adhesive to form a repairing sheet. A thermosetting epoxy resin adhesive is impregnated on the nonwoven fabric portion of the repairing sheet, the nonwoven fabric portion is closely stuck on the inner wall face of a concrete sewer pipe with cracks, the repairing sheet is stuck on the whole inner wall face, and it is supported by a cylindrical rubber balloon from the inside. The planar heating element is excited and heated for about 1hr to harden the adhesive.
