PROBLEM TO BE SOLVED: To provide a conduit lining technique which can certainly cool a conduit lining material in a less costly manner following heat-curing. SOLUTION: First, a tubular conduit lining material 3 impregnated with a heat-curable resin, is inserted into a conduit 1, and the heat-curable resin is cured by jetting vapor 20a to the conduit lining material 3, with the conduit lining material 3 inflated to be pressed to the intraconduit peripheral surface of the conduit 1. Further, hot water 18 reserved at the bottom of the conduit lining material 3, is poured out by means of a pump 42 to the outside and then, is cooled by a cooler 43. After that, cooling water is jetted to the conduit lining material 3 after curing through a hose 30. Thus a water wagon dedicated for cooling is not necessary, so that a road occupancy area at a construction site can be reduced to save water consumption to be used for construction.
