Generally, when a water pipe buried in an underground is used for a certain period of time, the inner surface is corroded, and foreign matter contained in the raw water adheres to form a scale.

As described above, when the inner surface of the water pipe is corroded and the scale is formed, the water quality of the raw water is lowered and the old water pipe buried at regular intervals is replaced with a new water pipe due to the leakage of water due to the corrosion part breakage.

Meanwhile, as described above, in order to replace the sewer pipe, it is necessary to control the traffic of the road and excavate the road. Therefore, there is a problem that the traffic obstacle is caused and a lot of expenses are required. Therefore, And a method of inserting a polyethylene liner into a ward tube and rehabilitating it is used.

However, there is a problem in that the length of the folded liner wound on the folded liner roll is limited depending on the size of the rolled tube in the conventional regenerating tube, which limits the length of the regenerated tube.
