<p>PURPOSE:To execute the simultaneous connections of pipings and communication cables by forming a sleeve having a flange having an adaptor installing part for connecting communication cables in its center inner side in the connecting part of pipings through a ring seal material. CONSTITUTION:A communication cable 2 is disposed on the inner surface of a piping 1 with being buried in a liner material 3. A sleeve 10 is provided with a flange 12 having an adaptor installing part 13 formed on its body part 11 center inner side. A ring seal material 18 is installed between the sleeve body 11 and the piping 1 followed by fastening. An adaptor 17 is installed to the adaptor installing part 13 of the flange 12 of the sleeve 10. The connection of the communication cables 2 are achieved by connecting plugs 18 in their end parts to each other through the adaptor 17. Consequently, the connections of the pipings themselves and the communication cables can be achieved simulta neously by a simple method.</p> |
