Abstract
The device is a Full Displacement Pile Tip (FDPT) with a sacrificial drill bit that is connected to a steel pipe, where the tip comprises at least four flanges or fish tails at the cutting edge extending from a conical, dome-like bottom, and integrally connected to the cutting teeth along the tip's axial shaft. The purpose of the FDPT is allow a steel pier to be screwed into the ground to serve as a foundation for a structure. This is a single operation where the FDPT and pipe remain in the ground. There is no removal of FDPT, minimal pouring of concrete, and there is minimal soil spoilage. A smaller drilling rig can be employed to save operating costs.
