<p>PROBLEM TO BE SOLVED: To proved a rod for feeding in a pipe line in which a cable is already laid which allows smoothly inserting a cabling rod into an existing cable pipe line by a simple configuration without using an aspirator or the like even in an existing pipe line in which many cables are stacked like stacked straw bags to be laid in pipe line having many bent parts. SOLUTION: A cabling rod 16 having bending rigidity of 3.5×106 kg/mm2-5.5×106 kg/mm2 is inserted into an existing pipe line in which many cables are stacked like stacked straw bags, whereby less waviness is made in the pipe line 12 so as to easily insert the cabling rod 16. The outside diameter of the cabling rod 12 is 12 mm-15 mm, which leads to easy insertion, simple manual operation at work and easy handling in a place of a limited space such as in a manhole.</p> |
