RESIN INJECTION METHOD FOR PIPE LINING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a curable resin injection method for simply injecting a curable resin of the required amount from an optional site into an optional section inside the pipe lining material and also repairing a cut opening section of the pipe lining material by the heat welding. SOLUTION: A resin injection tube 5 is rolled about and inserted by the fluid pressure into a pipe lining material 1 with its outer face coated with a plastic film of high airtightness, and an uncured thermosetting resin 2 is injected into the pipe lining material 1 through the inside of the resin injection tube 5. In concrete, a part of the pipe lining material 1 is cut and opened to form an opening, and the fluid pressure is applied to the resin injection tube 5, and the resin injection tube 5 is rolled about and inserted from the opening into the pipe lining material 1.
