CABLE-LAYING METHOD AND CABLE-FEEDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a cable-laying method for feeding cables without loosening. SOLUTION: A cable drum 5 winding a long-length cable is installed to be rotatable on a man-hole 2. A long-length cable 3 fed from the cable drum 5 is extended for laying within a tunnel 1 as the cable-laying path. In this case, the long-length cable 3 is fed by the cable-feeding apparatus 47 provided on the ground from the cable drum 5 for the purpose of laying, while constant braking torque is always applied to the cable drum 5 on the ground with a brake which can regulate braking force.
