<p>PROBLEM TO BE SOLVED: To reinforce a pipeline easily and certainly regardless of the shape of a pipeline to be reinforced, by impregnating a liquidized resin into a cylindrical braid and also enlarging the diameter of the cylindrical braid after the cylindrical braid which can be freely extended and shrunk in a diametral direction is inserted to and passed through the inside of a pipeline, and after that, curing the resin impregnated. SOLUTION: In the case that a pipeline 3 is reinforced, one end of a cylindrical braid 2 is connected to a tow wire 1 led to a pipeline P, and the cylindrical braid 2 is inserted to and passed through the inside of the pipeline P from one end P1 of the pipeline P toward the other end side P2 thereof by being towed. Next, after a pair of pigs 6A, 6B and a lining agent (s) are integrated and led to the inside of the cylindrical braid 2, and the lining agent (s) is poured between the pigs 6A, 6B, the pigs 6A, 6B and the lining agent (s) are integrated and pneumatically carried toward the other end side P2. Hereby, the lining agent (s) can be impregnated into the cylindrical braid 2, and also the diameter of the cylindrical braid 2 is enlarged so as to be kept in a condition that it is arranged along the inner wall of the pipeline P, and after that, a fiber reinforced plastic body is formed in the target pipeline P to be reinforced by the curing of the lining agent (s).</p> |
