<p>PROBLEM TO BE SOLVED: To facilitate the lead-in work of a lining pipe in reinforcing or repairing a pipe by inserting the lining pipe in the pipe by using an approximately cylindrical traction jig body for holding and protecting the lining pipe inward. SOLUTION: This traction jig G for a lining pipe used for leading the lining pipe made of polyolefine resin or the like in a pipe for repairing or reinforcing the existing pipe, e.g. a gas pipe, has an approximately cylindrical traction jig body B holding and protecting the lining pipe 2 inward. The traction jig body B is formed by using, e.g. various types of clothes. When this traction jig body B is led inside the pipe 1, a wire W is attached to an end of the traction jig body B and the wire W is pulled in the tip side of the pipe by a winch, etc., installed on the ground. After the lead-in work of the lining pipe 2, the traction jig body B is drawn out and removed.</p> |
