PROBLEM TO BE SOLVED: To provide a construction method for a bundled conduit line and a method for stringing an aerial cable in which, even if it is not only standard span between power poles but also long distance span between power poles, the aerial cable can be stringed between power poles without plastic deformation of a hanger.SOLUTION: A construction method for a bundled conduit line includes the steps of: supportedly fixing both ends of a first tow rope 22 stretched between power poles 20 and 21 to the power poles on both sides, respectively; and constructing the bundled conduit line between the power poles by sending out a suspension wire 32 and a hanger 33 connected to one end of a second tow rope 23, which is stretched between the power poles and not supportedly fixed to the power poles on both sides, to one power pole side while winding the hanger around the first tow rope on the other power pole side and by towing the other end side of the second tow rope from the one power pole side. |
