<p>PROBLEM TO BE SOLVED: To secure the tensile strength of a lining cylinder enough while the improvement of work efficiency is attempted. SOLUTION: In a method for lining the inside of a pip in which while a lining cylinder A is inserted into an existing pipe B, the inner and outer surfaces of the lining cylinder A are inverted in turn from the tip side in the insertion direction and the inner surface B1 of the existing pipe B is lined, while the lining cylinder in which a cylindrical braid 2 which can be expanded/contracted freely in the circumferential direction and longitudinal direction is inserted freely and relatively movably into a flexible tube 3 for forming an airtight layer is inserted into the existing pipe, the inner and outer surfaces are inverted in turn from the tip side in the insertion direction so that the cylindrical braid moves to the outer circumference side.</p> |
