Disclosed is a pipeline regeneration pipe with which necessary strength can be ensured by means of the inserted regeneration pipe itself without the necessity of grouting, the regeneration pipe being characterized by being configured of an inner wound flexible resin layer (5d) which constitutes the inner layer of a straight pipe part (5b), an outer wound flexible resin layer (5e) laminated on the outer surface of the inner wound flexible resin layer and constitutes the outer layer of the straight pipe part, and a protruded rim part (5c) helically formed on the outer surface of the outer wound flexible resin layer, the protruded rim part (5c) being configured by a rigid-resin core (5g) helically wound, and a core-covering part (5f) integrated with the outer wound flexible resin layer so as to surround the rigid-resin core. |
