Description
FIELD OF THE INVENTION

This patent specification relates to the field of helical piles. More specifically, this patent specification relates to a helical pile device that provides improved engagement with soil, fill, weather rock, and other substrates.


BACKGROUND

Helical piles, sometimes referred to as screw-piles, screw piers, screw anchors, screw foundations, ground screws, screw piles, helical piers, or helical anchors are a steel screw-in piling and ground anchoring system used for building deep foundations and retaining walls. Screw piles are typically manufactured from high-strength steel using varying sizes of square shafts or tubular hollow sections with helical flights. Generally, the pile shaft transfers a structure's/wall load into the pile/anchor. Helical steel plates are welded to the pile shaft to suit the site specific ground conditions. Helices can be press-formed to a specified pitch or simply consist of flat plates welded at a specified pitch to the pile's shaft. The number of helices, their diameters and position on the pile shaft as well as steel plate thickness are all determined based on the specific use application of the helical pile. However, existing helical piles are not suited for engaging with hard soil substrates, such as rock, since these hard soil substrates can damage the helical steel plates.


Helical piles are different from augers and are used for completely different applications. Helical piles are built and purposed to screw into a soil substrate without removing the soil substrate from the ground, as the helical pile relies on the weight of the soil substrate that is above the helical plates in order to secure the pile within the ground to enable it to perform its anchoring and deep foundation element functions. Conversely, augers are designed to completely disturb the soil substrate that they move through in order to remove the solid substrate that they contact from the ground.


Therefore, a need exists for a novel helical pile device. A further need exists for a novel helical pile device that provides improved engagement with soil/rock substrates and that does not suffer from the drawbacks of existing helical piles.


BRIEF SUMMARY OF THE INVENTION

A helical pile device is provided that is configured for improved engagement with soil substrates, including rocky and hard soil substrates, and that does not suffer from the drawbacks of existing helical piles.


In some embodiments, the helical pile device may include an elongated shaft having an exterior surface, an upper end, and a lower end. A flight blade having a helix shape may be coupled to the exterior surface of the elongated shaft proximate to the lower end, and the flight blade may have a leading edge and a trailing edge. A tooth coupler may be coupled to the leading edge of the flight blade, and the tooth coupler may have a tooth channel. The tooth channel may have a channel axis, and the channel axis may extend below the leading edge of the flight blade.


In further embodiments, the helical pile device may include an elongated shaft having an exterior surface, an upper end, and a lower end. A flight blade having a helix shape may be coupled to the exterior surface of the elongated shaft proximate to the lower end, and the flight blade may have a leading edge and a trailing edge. The flight blade may have an outer edge, and the outer edge may be between 85% to 115% of one complete helix turn. One or more pile teeth may be coupled to the leading edge of the flight blade.
