PURPOSE:To prevent the lapse of function as a communication cable by opening holes for inserting the communication cable through in the wall thickness part of a pipeline pipe body so as to form a perforated pipeline structure. CONSTITUTION:A perforated pipeline 1 is constructed providing a number of holes 3 for inserting a communication cable 4 through in a pipe body wall thickness part 2. As the communication cable 4 is disposed in the wall thickness part 2 of the pipeline pipe body, no problem is generated in case the communication cable is provided either inside or outside the pipeline. Moreover, as the communication cable 4 is inserted through the holes 3 of the pipe body wall thickness part 2, the deformation of the pipeline or the perforated pipeline 1 is transmitted to the communication cable 4, so that the communication cable 4 is prevented from the lapse or the rupture of its function. In case the communication cable 4 is damaged, the communication cable can be recovered simply without harming its fluid transporting function by pulling the communication cable 4 out and reinserting the repaired or a new communication cable 4 through the holes 3. |
