Abstract
Abstract A compression and tension load carrying ground or earth anchor having an elongated tubular pile member with tapered helical vanes therearound, a head plate at its upper end thereof, a cup slidable therein, tentacles depending from the cup, and tentacle bending orifices formed in the side wall. The vanes act as screw threads or plow shares when the pile member is driven in the ground, the head plate compacts the underlying earth and seals off any leakage path formed by the pile member or vanes, and the cup is forced downwardly in the pile member to extrude the tentacles through the bending orifices to form anchoring roots at one or more levels. The tentacles have barbed pointed ends fitting flush in the bending orifices. The tentacles may be tubular with orifices downstream from their pointed ends, orifices may be formed in the pile member and through the vanes and concrete may be pumped through the pile member and tentacles to flow through the orifices and form a bed of concrete around the anchor.
