Abstract
An anchor or foundation apparatus and a method for installing said apparatus in an earthen hole. The apparatus is equipped with outwardly extending moment resisting vanes. The apparatus employs pivotally swingable plates which swing in an arc upwardly or downwardly into the surrounding media to fix the device therein. The surface of the plates forced into the surrounding media is provided with oppositely disposed rib means extending along the upper and lower edges of the plates and said rib means serve as media containment means. The media containment means extends the zone of media consolidation and the plane for dislodgement of the device a considerable distance outwardly into the surrounding media. When the device is employed in the anchor mode the moment resisting vanes can be forced downwardly into the zone of media consolidation to provide enhanced resistance against moment imparting forces.
