ABSTRACT:
An elongated rod has a reaction member attached to a lower end with flukes adapted to be expanded outward against the reaction member. A lower tubular member is connected to the reaction member and surrounds the lower end of the rod. An upper end member is connected around the upper end of the rod and supports a connecting member. A plastic sleeve is located around the rod and is connected to the upper end member and to the lower tubular member forming a sealed chamber between the rod and the inside wall of the plastic sleeve. Two inlets extend through the upper end member to the chamber for injecting a liquid and a gas under pressure for providing protection for the rod. An enlarged bushing plate is coupled to the upper end member and to the rod by way of the plastic sleeve at a lower position for transferring a portion of the load applied to the connecting means to the wall of the hole.
