ABSTRACT:
A bearing pier foundation for compacting soil that includes a plug extending along the longitudinal axis having a first section and a second section. The first section adapted to receive a pushing force for pushing the plug into the soil and the second section adapted to rest on the soil to be compacted. A plane, which is perpendicular to the longitudinal axis, passes through the second section. The second section includes a first part and a second part. The first part has an inner edge and an outer edge intersecting the plane. The outer edge of the first part attaches to the first section and is positioned further away from the longitudinal axis than the inner edge of the first part. The second part has an outer edge attached to the first part inner edge. The second part extends downwardly from the plane and the second part has a tapering segment extending along the longitudinal axis and includes an upper end and a lower end. The upper end is positioned closer to the plane and has a larger geometric diameter than the lower end. The segment continuously tapers from the upper end to the lower end. The bearing pier foundation can be used in connection with a sheath which conforms to the outer surface of the bearing pier foundation. Further, the bearing pier foundation can be used in combination with a hydraulic setting tool. Also, disclosed is a method for installing the plug and sheath into the soil to compress and consolidate the soil thereunder.
