Abstract: An assembly for compressing a foundation piling prevents individual piling segments from sliding out of alignment. The assembly is an anchoring device that is lowered into a passageway running through a concrete or steel foundation piling to a desired depth. The anchoring device is suspended to a cable and has a center section and at least one moveable wing or wedge attached to the center section. Then a weight is dropped onto the anchoring device. The force of the impact causes the wings on the anchoring device to slide down and extend away from the center section. The force of the impact also forces the wings to grip the piling because the anchoring assembly is wider than the passageway when the wings slide down the center section. Tension is applied to the cable, which is now secured to the piling by the anchoring device. The tension in the cable creates a compressive state on the piling which prevents the individual segments from sliding out of alignment.
