titleOfInvention | Rehabilitation method of existing pipe and rehabilitation pipe |
abstract | (57) [Summary] [Purpose] The construction period and construction cost can be reduced. (EN) Provided is a method for rehabilitating an existing drainage pipe and a rehabilitating drainage pipe that does not cause damage or weakening of the existing drainage pipe. [Structure] A rehabilitation material 2 having elastically deformable plate-shaped segments 3 connected to each other via a hinge 4 in a tubular shape is held by a diameter-reducing jig 6 in a diameter-reduced state in which the segments 3 are curved. , The diameter of the rehabilitation material 2 is inserted into the existing pipe 1 in a reduced diameter state, and the diameter reduction of the rehabilitation material 2 by the diameter reduction jig 6 is released. Is expanded in the existing pipe 1 by the elastic force of the segment 3 itself to fix the segment 3 to the inner peripheral surface 1a of the existing pipe 1 by pressure, and the inner peripheral surface 1a of the existing pipe 1 is covered with the rehabilitation material 2. To do. |
