<p>PURPOSE:To easily lay a communication cable in the liner material of a fluid transporting tube by burying a communication cable leading-in wire material in the liner material, and securing the liner material to the inner face of the tube. CONSTITUTION:A liner material 3 embedded with a communication cable leading-in wire material 2 is secured to the inner face of a multifunctional tube 1. The material 3 which is formed in a tube state impregnated with thermosetting resin is employed. Thus, when a communication cable is connected to one end of the material 2 later and a communication cable laying towing machine is connected to the other, the cable can be laid in a space occupied by the material 2, the cable is not brought into contact with fluid, and the cable can be laid safely with high durability.</p> |
