The present invention relates to a conduit repairing material, repairing structure, and repairing method thereof, and particularly provides a repairing method for an existing conduit characterized by comprising using a plurality of reinforcing members capable of being carried in the existing conduit, assembling said reinforcing members into a hollow skeleton-like reinforcing body extending substantially along the inner surface of the existing conduit, attaching a plurality of inner face bars to the inside of the reinforcing body to assemble them into a tubular form along the lengthwise direction of the conduit, and injecting a curable infilling into the gap between the inner face bars and the inner surface of the existing conduit.

Repairing tube, method for repairing pipe lines therewith and method for

A lining material for pipe lines, especially those buried in the ground and a process for providing pipe lines therewith are disclosed, which includes a flexible tubular film, a sheet covering the outer surface of the tubular film and a film capable of being split off covering the outer surface of the sheet, characterized in that the sheet includes a fabric and a mat of fibers of high tenacity impregnated with a thickened liquid thermohardenable resin to form a fabric-fiber-reinforced composite molding sheet having a sufficient length and a width greater than the inner circumferential length of a pipe line to be treated, and that both lateral end portions of the sheet are slidably overlapped with each other to form a tube around the tubular film, the outer circumferential length of the tube being shorter than the inner circumferential length of the pipe line. The present invention is distinguished by using a specific fabric-fiber-reinforced composite molding sheet as the predominant constituent of the lining material in place of the conventional SMC and overcomes all the drawbacks in the prior art. The lining material is particularly suited for lining sewage pipes.
