  However, the one described in Patent Document 3 is such that the inner surface material made of synthetic resin is disposed along the circumferential direction of the inner peripheral surface of the existing pipe, so that the inner surface material is not uneven in the tube axis direction. Therefore, there is a problem that it is difficult to arrange the inner surface material with high accuracy as the repair length of the existing pipe line becomes longer.

  In view of such circumstances, the present applicant can simplify the installation work by eliminating the trouble of assembling the constituent members while allowing the inner surface material to be arranged with high accuracy, and has a long-term durability. A fixing member for fixing a ring-shaped support member of an inner surface material capable of constructing a certain pipe and an inner layer structure of the pipe using the fixing member have been proposed (see Patent Document 4).
