<p>PURPOSE:To improve the efficiency of a repair work by continuously executing a resin lining work in succession to the resin packing work in a pipe with one stage. CONSTITUTION:While the resin 20 connected to traction wires 4 which are inserted from one of both open ports of a pipe body 1 laid underground between manholes 3 and is held empty to the other and are pulled from the other open port is pushed, the resin 20 is packed into a pipe joint part 2, a corrosion hole 29, etc., and thereafter the excess resin exclusive of the packed resin 20 is removed. The inside surface of the pipe 1 packed with the resin 20 is then lined with a resin 21. The packing of the resin 20 into the joint part 2, the corrosion hole 29, etc., and the work to line the resin 21 to the inside surface of the pipe 1 are continuously executed with one stage. The repair work is efficiently executed in this way.</p> |
