<p>PROBLEM TO BE SOLVED: To provide a method for managing a temperature in an underground pipeline repairing process capable of sensing a thermosetting part of a portion corresponding to a damage part of an underground pipeline at a thermosetting resin of a liner and the liner for repairing the pipeline. SOLUTION: In the underground pipeline repairing process having the steps of inserting a cylindrical bag-like liner 4 impregnated with a thermosetting resin into an underground pipeline 2 to be repaired, then supplying a fluid to an inside of the liner 4 to thereby pressure contact the liner 4 with an inner surface of the pipeline 2, and heating the liner 4 by a heater 27 in this state to cure the thermosetting resin, the method for managing the temperature comprises the steps of specifying a part to be inferred so that a temperature of the liner 4 becomes low at a liner 4 heating time from a shape and a disposition of the pipeline 2, previously mounting a temperature sensor 22i at the liner 4 of this specified part, and obtaining an arrival of the thermosetting resin from a temperature detection signal to be output from the sensor 22i at the heating time of the liner 4 inserted into the pipeline 2 at the curing temperature.</p> |
