ABSTRACT:
Expansible anchors, particularly a pivotable anchor for pilings. The anchor is characterized by a backing plate which is secured to the lower exterior portion of the piling. A pivot bracket extends laterally outward of the backing plate to support a pivoting arm and thrust plate. As the piling is being driven, the pivoting arm and thrust plate are pivoted upwardly in substantial alignment with the piling vertical axis. As the piling is driven and set, the pivoting arm and thrust plate are pivoted downwardly to a laterally outward locking mode. The surrounding marine surface then settles upon the thrust plate, locking the piling in place.
