    摘要: The present invention provides a repairing tube to be used in pipe lines such as gas conduits, water supply lines and sewer lines, chiefly those buried in the ground, for the purpose of repairing the pipe lines. More particularly, the present invention relates to a repairing tube including a rigid pipe formed of thermoplastic resin and a tubular woven fabric and a method for repairing or reinforcing a pipe line with the repairing tube. Furthermore, the present invention relates to a method for removing the repairing tube in its collapsed form out of the pipe line, for example when the repairing tube installed in the pipe line has become superannuated or it has been collapsed for some reason or other to impair the function of the pipe line and hence it is desired to reline the pipe line.

    摘要: 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.
