<p><P>PROBLEM TO BE SOLVED: To provide a pipe lining method capable of ensuring high airtightness in a pipe lining material to certainly prevent leakage of a pressure fluid to the outside of the pipe lining material. <P>SOLUTION: In the pipe lining method performed using the pipe lining material 5 constituted by impregnating a tubular resin adsorbing material with an uncured curable resin, a start liner 3, which is obtained by applying a plastic film having high airtightness to the outer surface of the tubular resin adsorbing material, is inserted into a pipeline 10 and the pipe lining material 5 is subsequently reversed to be inserted into the start liner 3 in such a state that the start liner 3 is internally reduced in pressure (while the start liner 3 is evacuated). Then, the pipe lining material 5 is pressed to the inner surface of the pipeline 10 by allowing the pressure of a fluid to act on the interior of the pipe lining material 5 to cure the curable resin infiltrated in the pipe lining material 5. <P>COPYRIGHT: (C)2004,JPO</p> |
