Title: Cable-passing construction method and corrugated tube used therefor
Inventor: KAJIKAWA TOSHIICHI
IPC: G02B6/46
Filed: 2000-05-12
Abstract: PROBLEM TO BE SOLVED: To use a corrugated tube for a conduit line in a construction method, in which a cable is passed through the conduit line by using the viscous force of airflow. SOLUTION: The conduit line 14, through which the cable 16 is passed is constituted of the corrugated tube.
