<p><P>PROBLEM TO BE SOLVED: To simply/quickly/inexpensively underground an electric wire by directly laying and burying a cable by using an underground conduit pipe to a dug laying groove. <P>SOLUTION: The device 1 for undergrounding an electric wire is provided with a cable drum 4, to which the cable 6 is mounted, a conduit pipe drum 3, to which the underground conduit pipe 5 having flexibility in the longitudinal direction and provided with a circumferentially freely openable roll cross-sectional shape is mounted, a cable insertion unit 7, in which the cable 6 fed out from the cable drum 4 is inserted to its inside in a state that the pipe outer periphery is made open by pushing open the underground conduit pipe 5 fed out from the conduit pipe drum 3 from the inside, a squeezing part for squeezing the underground conduit pipe 5 passed through the cable insertion unit 7, a cable laying part 9 for laying the underground conduit pipe 5 passed through the squeezing part to a previously dug burying groove, and a traveling body 2 capable of self-propelling, to which the cable drum 4, the conduit pipe drum 3, the cable insertion unit 7, the squeezing part, and the cable laying part 9 are installed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
