Abstract: An improved wing-type ground anchor. The ground anchor includes a central body portion, wings radiating laterally from the body portion, and a leg portion at the front end of the body portion GROUND ANCHOR that operates like a star-point drill for penetrating the ground. The sides of the leg portion each include a plurality of sharpened leading side edges which are longitudinally offset from each other. Each of the wings also includes a plurality of sharpened leading side edges which are longitudinally offset with respect to each other. The offset leading side edges and wing edges progressively extend greater distances laterally outward from the body portion along the length of the leg portion and the wings. Since smaller side edges and wing edges are advanced first, the staged side and wing edges facilitate passage of the ground anchor through soil.

Abstract: A system and method are provided for driving a ground anchor and associated anchor rod into the ground. The ground anchor is held securely relative to a drive gad which is reciprocated bi-directionally with an actuator. One end of the anchor rod is pivotally connected to the ground anchor. Another end of the anchor rod is connected either to the drive gad or to the actuator so that the anchor rod is caused to vibrate positively in phase with the anchor. The vibrating anchor liquefies the ground and can be pushed easily through the ground to a desired anchoring position.
