A method and apparatus place an auger grouted displacement pile or helical pile in soil. The pile has an elongated shaft with at least one lateral compaction protrusion which establishes a regular circumference in the supporting medium. The pile also has a helical blade configured to move the pile into the supporting medium. The bottom of the shaft includes means for forming irregularities in the circumference after compaction by the lateral compaction protrusion. The bore is filled with grout while leaving the pile in the soil.

The invention relates to a method and a device for producing a foundation element in the ground, wherein a hole is formed in the ground which is filled with a hardenable filling mass in order to form the foundation element. According to the invention provision is made in that prior to the hardening of the filling mass a data carrier is introduced into the hole, on which information on the produced foundation element is stored .

A pile includes a first pile section having a first end that engages a supporting medium and an opposing second end. A first end of a second pile section is engageable with the second end of the first pile section, each of the first and second pile sections having mating end fittings that create an in fit. A sleeve overlays the first and second engaged ends of the first and second pile sections. At least one through hole aligned with at least one corresponding through hole of the first pile section is sized for receiving a fastener far securing the sleeve to the first pile section. In another version, the ends of the pile section are engaged in contact while the overlaying sleeve has a pair of interlocking sleeve or coupler portions that are configured to provide torsional resistance. Additional pile sections can be sequentially attached to the second pile section.

Provided are a concrete foundation structure capable of firmly fixing a precast concrete foundation to a ground, and a method for constructing the concrete foundation structure. A concrete foundation structure 10 includes a precast concrete foundation 16 having a projecting portion 30 embedded in a ground G. An anchor plate 20 is placed inside an excavation hole 18 formed in the ground G, and the precast concrete foundation 16 and the anchor plate 20 are connected by a connecting member 22. In the excavation hole 18, a backfill portion 24 is formed of a backfill material 94 including a solidifying material and soil. A filler layer 26 is formed of a filler 96 containing a solidifying material between the precast concrete foundation 16 and the backfill portion 24. The precast concrete foundation 16 has a through-hole 42 through which the connecting member 22 is inserted, and the filler 96 forming the filler layer 26 is filled through the through-hole 42.

Provided is a helical pile having an elongated shaft, at least one helical blade on the shaft having a leading edge and a trailing edge, and a displacement paddle extending outward from the shaft longitudinally positioned between the leading and trailing edges of the blade to push away soil to create a grout channel surrounding the shaft. At least one grout propeller may be provided on the shaft, having at least one blade pitched an opposite direction from the helical blade to propel grout downward in the grout channel as the pile rotates.
