Ground anchor with downward biased compression cap

Abstract

A ground anchor (10) for boring in soil (90) generally includes an elongate shank (20) having auger blades (34) on its lower end (30) and a attachment mechanism (41) on its upper end (40) for attachment of anchor lines (48), a compression cap (60), and one or more biasing springs (50). Biasing springs (50) operate between upper end (40) of shank (20) and compression cap (60) for maintaining cap (60) biased in a downward direction so that soil between cap (60) and auger (34) remains compressed at all times. Compression cap (60) includes a plate (62) that is freely journaled on shank 20 above blades (34) such that plate (62) can freely tilt through a tilt angle to align with surface (91) of soil (90).
