Description of the Related Art Cables such as power lines and communication lines have been mainly buried underground in order to enhance road scenery and to ensure smooth road traffic. In order to supply power and telegraph from general trunk cables to stores and homes as general consumers, handholes are installed at intervals of 40 to 50 m along the underground trench where trunk cables are stored. In general, a method is used in which a trunk cable is branched at a handhole closest to a store or a house to be used and wired, and the branched cable is wired to a store or a house.
