UNDERGROUND POWER CABLE CONSTRUCTION METHOD OF MULTI-CIRCUIT AND MULTI-SPAN

摘要

PURPOSE: An underground power cable constructing method of multi-circuit and multi-span is provided to simultaneously pull multi-circuits at one time, thereby shortening construction time. CONSTITUTION: A first multi circuit selecting device(10) on which at least three cable drums(11) are loaded is installed on one side of a first manhole(102) which connects a first underground span(101) to the ground. A multi circuit pulling device(20) is installed in a second manhole which connects the first underground span to the ground. A multi circuit cable is selected by the first multi circuit selecting device and inserted into the first underground span. A multi circuit cable is pulled in the multi circuit pulling device.
