PURPOSE: A method for inverting a pipe lining material and a pipe lining method thereof are provided to invert the pipe lining material in the pipe by using pneumatic pressure instead of hydraulic pressure without the deformation of the storage container. CONSTITUTION: A pipe lining material(20) is formed by covering the outer surface of a tubular resin absorbing material impregnated with liquid resin with plastic film. The pipe lining material is folded and contained in a storage container(30), and the end of the pipe lining material is folded and contacted to an inverting nozzle installed in the storage container. The pipe lining material is inverted by applying pneumatic pressure to the storage container. A support bar(16) is inserted to the layers of the inverting nozzle, and both ends of the supporting bar are fixed to the side of the storage container. |
