Disclosed is a trenchless pipeline repair member with an enhanced sealing ability, comprising a sleeve, a guide belt, a rubber pad, a waterproof pad, and a fixing wire. The present invention has a double sealing structure that the rubber pad primarily blocks leakage of contaminated water and secondarily the waterproof pad blocks leakage of the contaminated water, between the sleeve and the pipeline, when the present invention is installed in a faulty area of a pipeline, thereby surely blocking the leakage of the contaminated water. Since the fixing wire holds the outer surface of the waterproof pad and a protrusion for slip prevention provided on the rubber pad holds the movement of the rubber pad, deformation and position change of the rubber pad and the waterproof pad do not occur. Therefore, the present invention substantially reduces a failure rate when installing the present invention in the faulty area of the pipeline. |
