<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive pipe lining method capable of efficiently curing the resin infiltrated in a pipe lining material without using a hot fluid when a large caliber pipeline is regenerated using a large diameter pipe lining material. <P>SOLUTION: The pressure of a fluid is allowed to act on the folded-back back side of the pipe lining material, the pipe lining material is drawn out along the pipeline while reversed from a reversing nozzle, the reversed pipe lining material is arranged along the inner wall of the pipeline, a movable heating device equipped with a lamp heater for radiating heat rays is introduced into the reversed pipe lining material and moved through the pipeline in a state that the lamp heater is held so as to all over irradiate the whole periphery of the reversed pipe lining material by the lamp heater and heat rays are radiated from the lamp heater to radiate and heat the pipe lining material moved along the inner wall of the pipeline so as to cure the thermosetting resin infiltrated in the pipe lining material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
