PIPE LINE REPAIRING TECHNIQUE AND PIPE LINING STRUCTURE

摘要

PURPOSE:To satisfy a plurality of characteristics to be required for a lining at the same time. CONSTITUTION:A separate tubular lining material (open liner) 8 impregnated with curing resin is reversed and inserted into a tubular lining material 3 impregnated with curing resin different in kind from the curing resin, while pressing both the tubular lining materials 3, 8 against an inner circumferential surface of a worn pipe 1 by fluid pressure, the curing resin infiltrated into those lining materials are cured, through which the inner circumferential surface of the worn pipe 1 is lined with a rigid lining pipe having an inner and outer cylindrical structure. Therefore, for example, an outside rigid lining pipe is made into one having high pressure resistance and an inside rigid lining pipe can be made into one having high corrosion resistance and it becomes possible that plurality of characteristics to be required for a lining can be satisfied at the same time.
