ABSTRACT:
A tubular structure (21) composed mainly of a sheet material (22) formed from a thickened solution of an ultraviolet-curing resin in which high-strength fibers are dispersed, is inserted into a pipeline (7) so as to face a damaged part (26) thereof, is expanded into intimate contact with the inner surface of the pipeline (7), and is irradiated with ultraviolet light on its inner surface, whereby the resin is cured. Sealing members (24, 24') capable of swelling with water are fitted about the opposite end portions of the tubular structure (21) so that the sealing members (24, 24') may be located on the opposite sides of the damaged part (26) of the pipeline (7) from each other.
