Abstract
Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.
Claims15
A method of recovering space in a longitudinally extending underground conduit having at least one active cable positioned within a longitudinally extending duct which is in the conduit comprising the steps of moving the duct out of the conduit, and as the duct is being moved, cutting the duct so that the duct may be removed from around the cable, thereby recovering space in the conduit while maintaining the active cable in the conduit.
A method of utilizing a device to recover space in a longitudinally extending underground conduit having at least one active cable positioned within a longitudinally extending duct which is in the conduit comprising the steps of using the device to longitudinally cut the duct, and using the device to remove the duct from around the active cable thereby recovering space in the conduit while maintaining the active cable in the conduit.
A method of recovering space in a longitudinally extending conduit having at least one active cable positioned within a longitudinally extending duct in the conduit comprising the steps of accessing the conduit and the duct in a manhole, pulling the duct a short distance into the manhole, engaging the duct, moving the engaged duct toward a blade assembly in the manhole, cutting the duct in the manhole longitudinally into at least two pieces, and removing the pieces from around the cable thereby recovering space in the conduit while maintaining the active cable in the conduit.
