AUGER GROUTED DISPLACEMENT PILE
First Claim
1. An auger grouted displacement pile for being placed in a supporting medium comprisingan elongated pile shaft having a top section and a bottom section,the bottom section further including:
- extending from the pile shaft, at least one lateral compaction protrusion which establishes a regular bore diameter in the supporting medium;
a helical blade having a first handedness configured to move the pile into the supporting medium;
means for forming irregularities in the bore diameter after compaction by the lateral compaction protrusion.

Abstract
Disclosed in this specification is a method and apparatus for placing an auger grouted displacement pile or helical pile in soil. The pile has an elongated shaft with at least one lateral compaction protrusion which establishes a regular bore diameter in the supporting medium. The pile also has a helical blade configured to move the pile into the supporting medium. The bottom of the shaft includes means for forming irregularities in the bore diameter after compaction by the lateral compaction protrusion. The bore is then filled with grout while leaving the pile in the soil.

15. A method for placing an auger grouted displacement pile in a supporting medium comprising the steps of
placing an auger grouted displacement pile on a supporting medium surface, the pile having: -
an elongated pile shaft having a top section and a bottom section, the bottom section further including; at least one lateral compaction protrusion which establishes a regular bore diameter in the supporting medium; a helical blade having a first handedness configured to move the pile into the supporting medium; means for forming irregularities in the bore diameter after compaction by the lateral compaction protrusion; rotating the auger grouted displacement pile such that the helical blade pulls the auger grouted displacement pile into the supporting medium while the lateral compaction protrusion compacts the supporting medium; adding grout to the top section of the auger grouted displacement pile; and allowing the grout to set while the auger grouted displacement pile is still embedded in the grout. - View Dependent Claims (16, 17)
