Abstract: A foundation repair piling made up of segments is post tensioned by a cable fed into the segments after the piling is installed. A cable anchor serves as a base segment of multiple concrete piling segments. After installing all the concrete segments on top of the base segment, a cable is inserted into passages in the segments. The cable is threaded through the completely installed piling segments and into the cable anchor. After the cable bottoms out in the cable anchor, upward tension is applied to the cable. As the cable is pulled, cable lock members in the cable anchor increase gripping pressure even as the cable tension increases, thereby solidly anchoring the end of the cable in the cable anchor. After the desired tension is reached, the cable is terminated at the top of the last segment. The tension is held by a termination lug at the top end of the cable.

Abstract: An assembly and a method 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.

Abstract: A method for securing piling segments together to form a single foundation piling using an alignment securing assembly and vibrations sent through the piling as. Piling segments are driven into the ground on top of each other, forming a piling. A single piling passageway is formed when the piling segments are in alignment. An alignment securing assembly is placed in the passageway. Vibrations are sent through the piling so that grout will not gather in the upper portions of the passageway before the lower portions of the passageway are filled with grout. The grout cures and the piling segments are secured so that the segments will not slip. The alignment securing assembly uses an anchoring device that is lowered and set in the passageway so that tension can be applied by a cable. The tension from the cable and anchoring device causing a compressive effect on the piling.

Abstract: Pilings are installed for leveling a foundation. A first segment is driven into the ground. Then two support rods of varying length are positioned and grouted into a passage running through the segment. The first support rod is one-half of the height of the piling segment, while the second is one and one-half times the height of the piling segment. An additional piling segment is driven on top of the first segment. Support rods which are twice the height of a single segment are positioned and grouted into the passage. This process is repeated until the assembly is the required depth.

Abstract: A device and method are provided for leveling and supporting a slab foundation on a column of piling sections. A vertical hole is bored through the slab foundation and an anchoring cylinder is inserted in the hole. An adhesive is used to adhere the outer surface of the anchoring cylinder to a portion of the foundation. The cylinder has a plurality of downward-facing load shoulders which are engaged by upward-facing shoulders of a reacting member positioned across and above the hole. Piling sections are inserted into the anchoring cylinder and forced into the earth with a driving device that reacts against the reacting member. The anchoring cylinder is then supported on the piling sections to maintain the desired level of the foundation.

Abstract: A metallic piling sleeve member filled with solidified or cured cementitious material and a hollow, cylindrical outer sleeve member having a diameter larger than that of the metallic piling sleeve member are provided. The outer sleeve member is placed generally concentrically around the piling sleeve member and the piling and outer sleeve members are vertically driven into the soil. Further metallic piling sleeve and outer sleeve members are successively vertically driven into the soil until the piling is complete and the metallic piling sleeve and outer sleeve members abut one another in vertical relation.
