METHOD FOR MAKING REGENERATED PIPE

PROBLEM TO BE SOLVED: To provide a method for making a regenerated pipe for regenerating an existing pipe of long distance even under the condition where water does not flow into the existing pipe. SOLUTION: In the method for making the regenerated pipe Sa for making the regenerated pipe Sa by the pipe making machine 1 in which a profile 100 is pulled into a manhole M1 from above a ground and wound in a spiral shape, a molten resin is applied to at least one of one side edge and the other side edge of the spiral-shaped profile 100 adjacent each other, the regenerated pipe Sa is made by overlapping and bonding the same, and the regenerated pipe Sa thus made is inserted in the existing pipe while rotating the same, the regenerated pipe Sa of a set length is made, the regenerated pipe Sa thus made is cut and pulled in a pipe making direction, the regenerated pipe of the set length is newly made, the newly regenerated pipe is cut and pulled in the pipe making direction, a connecting member is bonded over the rear end side inner peripheral face of the regenerated pipe Sa made earlier and the front end side inner peripheral face of the regenerated pipe Sa newly made, and the front and rear regenerated pipes are connected.
