Abstract
A screw pile substructure support system comprises a tubular pile with a fixed conical tip having a helical flight thereon which draws the pile into a soil bed when a torque is applied to the pile. The tip has a substantially conical shape, and the largest diameter of the tip is substantially the same as the diameter of the tubular pile to which it is attached. The helical flight is attached to the outside surface of the tip. The tip may also be provided a point tip and one or more cutting teeth attached its surface.
Claims17
A screw pile substructure support system, comprising:
- a tubular pile having a centerline and a first diameter;
- a substantially conically shaped pile tip sharing a centerline with the tubular pile, the substantially conically shaped pile tip having a first end and a second end, the second end being connected to the tubular pile and having a second diameter;
- and
- a helical flight attached to an exterior surface of the substantially conically shaped pile tip, wherein the first diameter is substantially similar to the second diameter.
