Abstract: PURPOSE: A sewer pipe repairing and reinforcing method is provided to repair and reinforce the inside of a sewer conveniently by movably extrusion-molding the adhesive thermosetting resin, and to reduce working hours and expenses. CONSTITUTION: Two kinds of thermosetting resins having low viscosity are mixed, and extruded in a moving extruder(20) installed in a sewer pipe. A resin pipe(29) for repairing and reinforcing is formed with heating and hardening by contacting to the wall of the sewer pipe. The monomer thermosetting resin is extrusion-molded with cellulose for reinforcement of the resin pipe, and aluminum powder is added to the thermosetting resin to improve abrasion resistance. The mold release is formed to simply separate the resin pipe from the heating apparatus. The end of the sewer pipe is sealed with a cover(32) to form the resin pipe evenly. The cover is fixed in the extruder to the specific internal pressure of the cover in extruding the mixed resin, and the cover is separated from the extruder in filling the resin. The extruder forms the resin pipe in the sewer pipe by moving backward.
