<p>PURPOSE:To provide an execution method for the perfect seal in the connection of a branched pipe with a regeneration repair execution pipe. CONSTITUTION:An installation hole 35 which is slightly larger than the outside diameter of the bulging-out part 31 of the pipe body 26 of a stud pipe 25 is drilled on a regeneration repair execution pipe 1, and the bulging-out part 31 is inserted. A seal rubber 27 is pushed in from the gap between the thin diameter part of the pipe body 26 and the installation hole 35, and the pipe body 26 is pulled upward, and then the seal rubber 27 is pushed in around the bulging- out part 31. A nut 20 is screwed into a PTR screw 29 at the upper end of the pipe member 26 through a saddle 14, and fixed. Then, resin is poured from a nipple 16, and then the inside of a recess 19 is charged with the resin, and a branched pipe can be fixed perfectly airtightly.</p> |
