<p>PURPOSE:To use a resin sheet filling a water-leaking part of an existing pipe so that the sheet may surely make pressure contact with the inner surface of the pipe without getting out of position. CONSTITUTION:In a jig 1 for correcting the leaking part provided with a cylindrical tube 2 for application which can swell in the tube diameter direction in order to apply and harden an FRP sheet 7 not hardened yet to the leaking part 6 of an existing pipe 5 from the inner side of the pipe, the thickness of the center 4 in the tube axial direction of the tube 2 for application is made thicker than the neighboring both sides. When an inner pressure is loaded to the inside of the tube 2, the center 4 in the axial direction swells in the tube diameter direction without converting largely the initial cylindrical section form, and the FRP sheet 7 can be brought into pressure contact with the inner surface of the existing pipe 5 securely without getting out of position.</p> |
