PURPOSE: A device for generating curing heat supplied to a reversible tube for non-digging repair of a pipeline is provided to simplify the structure by removing a separator or steam trap and easily control temperature by using electric heaters. CONSTITUTION: A device for generating curing heat supplied to a reversible tube for non-digging repair of a pipeline comprises a basing heating module(10). The basic heating module comprises a heating channel(12), a heat insulating material, a heater supporting plate(16), and electric heaters(18). The heating channel has a side opening on one side, an inlet and an outlet on both ends thereof, and a hot air passage(13) with a square cross section between the inlet and the outlet. The heat insulating material encloses the inner periphery of the heating channel. The heater supporting plate is located at the side opening of the heating channel. The electric heaters are installed in a U-shape on the heating plate and arranged in the longitudinal direction of the heating channel. |
