A structural helical pile having an elongate shaft member defining a
longitudinal axis. The structural helical pile also comprises a radially
extending, generally helical load bearing member integral with the shaft
member and projecting outwardly from the longitudinal axis of the shaft
member. The helical load bearing member has a leading edge and a trailing
edge. The respective leading and trailing edges intersect the shaft
member in spaced relationship along the longitudinal length of the shaft
member. The helical load bearing member further comprises at least one
rib integrally formed therein. In this aspect, each rib extends outwardly
from the longitudinal axis of the shaft member and has a substantially
uniform cross-sectional thickness.
