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.

A screw pile substructure support system comprising:
- a tubular pile having a centerline and a substantially constant diameter throughout a length of the tubular pile;
- and
- a pile tip comprising:
- a tapered portion comprising a first end having a first diameter and a second end having a second diameter, wherein the first diameter is greater than the second diameter and about equal to the diameter of the tubular pile, and wherein the first end is attached to the tubular pile;
- a first helical flight attached to and extending along an exterior surface of the tapered portion;
- an end plate closing the second end of the tapered portion;
- and
- at least one protrusion extending outwardly from the end plate.
A screw pile substructure support system comprising:
- a tubular pile having a centerline and a substantially constant diameter throughout a length of the tubular pile;
- and
- a pile tip comprising:
- a frustro-conical section comprising a first end having a first diameter and a second end having a second diameter, wherein the first diameter is greater than the second diameter and about equal to the diameter of the tubular pile, and wherein the first end is attached to the tubular pile;
- a cylindrical section extending axially outward from the second end of the frustro-conical section;
- at least one helical flight attached to and extending along an exterior surface of the frustro-conical section and an exterior surface of the cylindrical section, each of the at least one helical flight being spaced apart from an end of the pile tip that is opposite the tubular pile;
- and
- an end plate coupled to an end of the cylindrical section and having a substantially flat surface disposed perpendicular to the centerline of the tubular pile and having a diameter about equal to the second diameter.
A method for installing a screw pile substructure support system comprising:
- attaching a pile tip to a tubular pile having a substantially constant diameter throughout a length of the tubular pile to form a screw pile, wherein the pile tip comprises:
- a tapered portion comprising a first end having a first diameter and a second end having a second diameter, wherein the first diameter is greater than the second diameter and about equal to the diameter of the tubular pile, and wherein the first end is attached to the tubular pile;
- a helical flight attached to and extending along an exterior surface of the tapered portion;
- an end plate closing the second end of the tapered portion;
- and
- at least one protrusion extending outwardly from the end plate;
- positioning the screw pile above a preselected location of ground;
- attaching a drill rig to the screw pile;
- and
- turning the screw pile to facilitate penetration of the ground.
