PROBLEM TO BE SOLVED: To simplify facilities for lining by respectively forming apertures at both the ends of a conduit to be the object of correction repair in extension direction and generating air currents for maintaining the viscosity of lining resin liquid as prescribed between these apertures. SOLUTION: A branch pipe 1 as a low pressure guide is embedded under a road L as a pipeline for gus supply and when executing the correction repair of that branch pipe 1, the extension of construction is determined. Then, shafts are respectively dug at both the ends of that construction extension direction, the branch pipe 1 is separated at these positions, and apertures 1A and 1B are provided. Then, a connecting pipe 5 communicated to an air blowing means 4 is connected to one aperture 1B and besides, a connecting pipe 7 communicated to a 6 is connected to the aperture 1A. Further, a heating blower 4A at the air blowing means 4 is set at an inside temperature so that the viscosity of lining resins can correspond to about 8200±500 mPa.s and besides, a regenerator 4B maintains external air exhausted from the heating blower 4A at a temperature adaptive to construction conditions.
