Abstract

See full text

A ground anchor is provided for driving into the ground for anchoring or supporting a structure. The ground anchor includes a hub with a helical load bearing screw and a pointed ground engaging end. The ground engaging end has a blade extending axially from the hub with first and second opposing major faces and first and second transverse faces that converge at the axial end to a flat axial face. The blade has one or more diagonal frangible portions to define a diagonal break line. The breakable portion of the ground anchor penetrates the ground and breaks away from the blade when a predetermined torque or stress is applied to the blade. The breakable portion breaks away to form a ground engaging end having a dimension and surface area that is larger than the original ground engaging end.
