Abstract

본 발명은 통신 케이블의 지하 매설을 위해 케이블 보호관내에 통신케이블을 인입시키기 위한 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for introducing a communication cable into a cable sheath for undergrounding the communication cable.

가요성의 통신 케이블(30)을 케이블 보호관(32)내에 인입시키기 위해 견인선을 이용하는데 본 발명에서는 케이블 보호관(32)의 압출 성형시 동시에 상기 견인선(14)이 안내봉(12)을 통과하면서 상기 케이블 보호관(32, 압출 수지관(10))에 인입되어 나오도록 하였다.A traction line is used to lead the flexible communication cable 30 into the cable protection tube 32. In the present invention, the traction line 14 passes through the guide rod 12 simultaneously with the extrusion of the cable protection tube 32. The cable protection pipe 32, the extruded resin pipe (10) was pulled out.

이와 같이 함으로써 각 케이블 보호관마다 일일이 견인선을 인입해야 하는 번거로음이 제거되었으며, 작업에 따르는 비용이 대폭 절감되었다.This eliminates the hassle of having to pull in the lead wires for each cable sheath and significantly reduces the cost of the work.
