Grout propeller for helical pile
Provided is a helical pile having an elongated shaft, at least one helical blade on the shaft having a leading edge and a trailing edge, and a displacement paddle extending outward from the shaft longitudinally positioned between the leading and trailing edges of the blade to push away soil to create a grout channel surrounding the shaft. At least one grout propeller may be provided on the shaft, having at least one blade pitched an opposite direction from the helical blade to propel grout downward in the grout channel as the pile rotates.
