To obtain a pipe, for synthetic resin cable protection, by which an operating space inside a main pipe is secured when the propulsion construction of the main pipe and the pipe laying construction of the pipe for synthetic resin cable protection are performed simultaneously and which can guarantee safety by a method wherein a socket is formed in one end of the pipe, a spigot which is inserted into the socket via a rubber ring is formed in the other end of the pipe and the rubber ring is bonded to the inside of the receiver opening by using an adhesive.
In a pipe for cable protection, one end of it is provided with a socket 11 whose outer face is smooth, the other end of it is provided with a spigot, and a rubber ring 2 is fixed, by an adhesive, to the inside of the socket 11. For example, a buffing treatment can be executed to the bonded face of the rubber ring 2 or to the bonded face at the inside of the socket 11. In addition, the socket 11 is formed in such a way that its diameter is molded so as to be expanded, and the receiver opening is fixed to one end of a straight pipe 13. Then, by taking into consideration a ventilation performance inside a main pipe, a system to connect the rubber ring 2 without using a solvent is adopted, and the safety hygenie of an operator can be guaranteed. In addition, since pipe can be laid at a minimum pipe laying pitch, it is possible to ensure a pipe laying space which is required when the propulsion construction of the main pipe and the pipe laying construction of the pipe for cable protection are performed simultaneously.
