<p>PROBLEM TO BE SOLVED: To provide a water-stopping method for the mounting spigot of a regeneration pipe, with which a underground main pipe is to be lined, embodied in such an arrangement that the connection part between the main pipe and mounting pipe is furnished with a through-hole and its peripheral edge is pushed wide toward inside the mounting pipe, so that the mounting spigot and a sleeve are formed consolidatedly, wherein a proper water-stoppage performance is generated surely by establishing tight attachment of the sleeve and mounting pipe, in the spigot forming works for the regeneration pipe. SOLUTION: A through-hole 31 is formed in the regeneration pipe 3, and prior to its being pushed wide, a sealing material 4 made of soft resin is sprayed against the inner surface of the connection part of the mounting pipe 2 connected with the underground main pipe 1 by the use of the through-hole 31, and the sleeve, formed by pushing wide the regeneration pipe 3, is put in tight attachment to the inner surface of the mounting pipe 2 via the sealing material 4.</p> |
