Auger grouted displacement pile

摘要

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 filled with grout while leaving the pile in the soil.

1. An auger grouted displacement pile for being placed in a supporting medium comprising
an 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, wherein the at least one lateral compaction protrusion is a gusset, wherein the gusset is above a topmost flighting of the helical blade and below a bottommost fighting of the helical auger.
