A connection line of an underground distribution line is provided to efficiently perform connection between underground distribution lines by easily controlling a connection position of the underground distribution line through an underground line transfer device. A rack(10) is installed in an inner wall of an underground tunnel(T). An underground line(L,L') is mounted in the rack. A protective unit includes a first cap, a second cap, and an injection hole. The underground line is inserted to the first cap. A second cap covers the underground line. An insulation material is injected in the first cap and the second cap through the injection hole. A clamp(20) is engaged with the underground line. A clamp transfer device(30) horizontally and vertically moves the clamp. A control unit(40) controls operations of a first motor and a second motor of the clamp transfer device. A proximity sensor(60) senses access of a mouse. An ultrasonic outputting device(70) outputs ultrasonic wave of a specific frequency band in order to prevent the access of the mouse. An input unit(50) controls an operation of the control unit. |
