An Earth Anchor Comprises An Elongated Square-section Tube Formed

An earth anchor comprises an elongated square-section tube formed in its sides with throughgoing longitudinally-spaced slots each of which lies in a respective plane perpendicular to the tube axis. The lower end of the tube is pointed and the upper end is open. A plurality of L-shaped anchor elements are provided in the tube and each have a flat anchored leg slidable transversely in a respective one of the slots and extending generally perpendicularly to the tube and a flat guide leg extending generally parallel to the tube and slidable transversely in the tube on the anchor leg of the underlying anchor element. The lowermost anchor element is slidable on the upper surface of a member constituting the pointed tip of the tube. A tool having a wedge-shaped lower end is pushed down through the tube after the tube has been driven into the ground so as laterally to slide the elements one after the other out of the tube and into the earth surrounding them. Thereafter a holding element such as another tube may be fitted into the interior of the thus- set arrangement in order to hold the anchor elements in their extended position.
