A method for repairing a tubular conduit.

摘要

An improved method for repairing a utility pipe (1) such as underground sewer pipe to internally line the pipe with a tubular liner (2) impregnated with a thermosetting resin; in this method, a hot water hose (6) having ejection holes (8) is inserted in the tubular liner bag to eject hot water to effect hardening of the thermosetting resin and this hose is provided with numerous floats (25) to float in the water even when the ejected water collects and floods inside the tubular liner bag; thus, efficient ejection of the hot water from the hot water hose is secured. <IMAGE>
