<p><P>PROBLEM TO BE SOLVED: To make a helical pattern cable hanger easily supportable on a messenger wire, to make a cable easily retractable to the helical pattern cable hanger without using a particular retracting work implement, so as to make the cable laying easily performable between electric poles. <P>SOLUTION: The construction method has a process of transfer feeding the helical pattern cable hanger A from one electric pole 13a side to the other electric pole 13b side by making the messenger wire 14 support the helical pattern cable hanger A to mount it in a direct acting rod 16 and to move it forwardly, and has a process of repeating the connection to each other between the other end of the helical pattern cable hanger A and one end of it connected thereto in the halfway of this transfer feeding by the helical pattern cable hanger coupling implement B for the cable laying. Further the construction method has a process that the helical pattern cable hanger A is removed from the direct acting rod 16 in the point of time the first helical pattern cable hanger A reaches the other electric pole 13b, thereater the cable 15 is inserted to be suspended in the inside of the helical pattern cable hanger A. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
