METHOD FOR REPAIRING CONDUIT

摘要

PURPOSE:To provide a method for repairing a conduit in which warm water can be effectively showered on an entire length of the conduit to prevent partial curing delay of a tubular lining material and the material can be uniformly and simultaneously cured over the entire length. CONSTITUTION:A method for repairing a conduit has the steps of expanding a tubular lining material 2 formed by impregnating with thermally curable resin in the conduit 1 by pneumatic pressure, inserting a warm water hose 6 into the material 2, and showering the water from the hose 6 to cure the resin impregnated into the material 2, and comprises the step of mounting a float 25 at the hose 6 to float the hose 6 on a surface of the water in the material 2. Since the hose 6 is floated on the water surface in the material 2 by the float 25 mounted thereat even in any state, the purpose is accomplished.
