PIPE LINING METHOD

摘要

PROBLEM TO BE SOLVED: To apply lining to a pipeine having a non-circular cross section over the entire periphery thereof in almost uniform thickness. SOLUTION: A first pipe lining material 2 is inserted into a pipeline 1 by fluid pressure while reversed and the curable resin infiltrated into the first pipe lining material 2 is cured while the first pipe lining material 2 is pressed to the inner wall of the pipeline 1 and, thereafter, a second pipe lining material 15 is inserted into the first pipe lining material 2 by fluid pressure while reversed and the curable resin infiltrated into the second pipe lining material 15 is cured while the second pipe lining material 25 is pressed to the inner peripheral surface of the first pipe lining material 2.
