Abstract:
Described is a device (410) for use in removing a conveyance member from a material. The device (410) includes a displacement element (412) for being placed at least partly around a conveyance member and for displacing material as the device is advanced along a conveyance member. The device (410) also includes a driven component for receiving a driving force for driving the device through material. The device can include a coupling element (418) for coupling the device to a shaft and a material loosener (414) including a drilling element. The material loosener can be operable to loosen material ahead of the displacement element as the device is advanced along a conveyance member. The drilling element can be coupled to a first wheel (436) and the coupling element can include a second wheel (434) cooperating with the first wheel to transfer rotational movement of a shaft to the drilling element.
