PURPOSE:To enable the title method to repair whatever pipe line such as a pipe line having holes or cracks, a tilted pipe line it may be, without hurting a pipe lining material, by a method wherein hydraulic pressure is fed within a flexible tube which is inserted into the pipe lining material and has high airtightness and curing resin infiltrated into the pipe lining material is cured under a state where the pipe lining material is pressed against an inner circumferential surface of the pipe line. CONSTITUTION:Compressed air and pressure water are discharged into the open air by flowing within a vessel 2 and connected plastic tube 17. A pipe lining material 14 is moved on a flow of the compressed air and pressure water in the direction of the flows and pulled into the plastic tube 17 smoothly and easily. when reversal of the plastic tube 17 is completed extending over the whole length of a pipe line 1, the pipe lining material 14 is pressed against an inner circumferential surface of the pipe line 1 by receiving pressure of the water or the compressed air. Curing resin infiltrated into the pipe lining material 14 is cured by heatring the same by keeping this state on. |
