DEVICE FOR MEASURING HEATING SOFTENING TEMPERATURE OF PIPE REHABILITATION MEMBER, AND HEATING APPARATUS EQUIPPED WITH THE SAME

PROBLEM TO BE SOLVED: To enable a pipe rehabilitation member to be heated until a hardly heatable part of the pipe rehabilitation member is sufficiently softened, because a softened state of the hardly heatable part thereof can be grasped from the result of measurement of a thermometer, and to preve...

Zusammenfassung:	PROBLEM TO BE SOLVED: To enable a pipe rehabilitation member to be heated until a hardly heatable part of the pipe rehabilitation member is sufficiently softened, because a softened state of the hardly heatable part thereof can be grasped from the result of measurement of a thermometer, and to prevent fuel and time from being wasted by excessively heating the pipe rehabilitation member.SOLUTION: A heating apparatus 10 for heating and softening the pipe rehabilitation member 100 includes a heating chamber 12 for housing the pipe rehabilitation member 100, and a heating softening temperature measuring device 14 that is mounted in the heating chamber 12. The heating softening temperature measuring device 14 includes a solid body (54) that is made of the same synthetic resin material as a synthetic resin material for the pipe rehabilitation member 100, and the thermometer (56) that is provided inside the solid body (54). In the heating softening temperature measuring device 14, the shortest distance from an outer surface of the solid body (54) to a temperature measuring element (56a) of the thermometer (56) is set in correlation with the thickness of the pipe rehabilitation member 100, and an environment closely akin to the hardly heatable part (108) of the pipe rehabilitation member 100 is created around the thermometer (56).
