<p>PURPOSE: To form a synthetic resin pipe on only damaged parts or degraded necessary and most limited parts in an existing pipe. CONSTITUTION: A housing pipe and inner tube 5 constitutes a pressure space, and a compression space Is formed by an expansion tube 6 fixed on the outer periphery of a support pipe 3. A liner material 14 having a drawing-in belt body held therein is inserted into the inner tube 5, and then the tip end of the liner material 14 is folded back so as to be tacked on the intermediate outer peripheral surface of the expansion tube 6. While applying a constant pre-pressure in the pressure space and pressurizing the outer surface of the liner material 14 of the inner tube 5, the drawing-in belt body 15 Is pulled In order to allow the liner material 14 to be moved to a predetermined position in the existing pipe 16. A pressurized fluid is supplied in the pressure space, and the end part of the liner material 14 is pressed and secured against the existing pipe 16 inner surface. Then, a pressurized fluid is supplied in the pressure space, and the liner material 14 is inverted and pressed against the existing pipe 16 inner surface.</p> |
