ABSTRACT:
An earth anchor is made from a length of tubing that has angle-cut ends and a pulling attachment pivotally attached to an axle attached across the tubing at right angles to the length of the tubing. The anchor is lowered into an earth bore in a relatively vertical position to be rotated axially via a pull-tension applied to link attached to the pulling attachment. Upward motion causes the anchor to rotate about the axle, burrowing into the surrounding earth until the anchor is lodged in a horizontal position in the earth bore. The link extends to above ground and has a suitable fixture for securing to an object to be anchored. A double-cone effect produced by the compacting action of the angled cut-outs and the continued upward pull via the pull rod, compacts the earth above the anchor in continually expanding cones, and fills the inside of the main body of the anchor with compacted ground.
