Publication number: 20240352758Abstract: In order to solve the foregoing problems, an object of the present invention is to provide a jig and a laying method capable of laying a branch wire which can avoid a contact with a house or passersby and eliminating an unbalanced load of a utility pole erected in a confined area. According to the present invention, since a first member of the jig is connected to a distal end of the utility pole by an upper branch wire and a second member of the jig is connected to the ground by a lower branch wire perpendicular to the ground, the utility pole can be laid in a confined area while securing an attachment angle of the upper branch wire with respect to the utility pole and eliminating an unbalanced load of the utility pole. By securing an optimum separation distance between the utility pole and the lower branch wire, a risk of contact with a house or passersby can be reduced.Type: ApplicationFiled: September 1, 2021Publication date: October 24, 2024Inventors: Soichi ISHIKAWA, Masaki WAKI, Hiroaki TANIOKA, Kenichiro YAMAZAKI, Kento BUNPHONG
