Abstract
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.

A structural helical pile, comprising:
- an elongate shaft member defining a longitudinal axis;
- and
- a radially extending, generally helical load bearing member integral with the shaft member and projecting outwardly from the longitudinal axis of the shaft member, said helical load bearing member having a leading edge and a trailing edge, wherein the respective leading and trailing edges intersect the shaft member in spaced relationship along said longitudinal length of the shaft member, wherein the helical load bearing member further comprises a plurality of ribs integrally formed therein, each rib extending outwardly from the longitudinal axis of the shaft member and being spaced substantially uniformly from an adjacent rib, and wherein the helical load bearing member has a substantially uniform cross-sectional thickness and a wave shape in a circumferential cross sectional dimension that extends through the plurality of ribs.
A method of manufacturing a structural helical pile, the method comprising:
- providing an elongate shaft member defining a longitudinal axis;
- forming a helical load bearing member, said helical load bearing member having a leading edge, a trailing edge, and a plurality of ribs integrally formed therein, each rib extending outwardly from an innermost edge of the helical load bearing member and being uniformly spaced from an adjacent rib, wherein the helical load bearing member has a substantially uniform cross-sectional thickness and a wave shape in a circumferential cross sectional dimension that extends through the plurality of ribs;
- and
- integrally mounting the helical load bearing member thereon the elongate shaft member such that the helical load bearing member projects outwardly from the longitudinal axis of the shaft member, wherein the respective leading and trailing edges intersect the shaft member in spaced relationship along said longitudinal length of the shaft member.
