    Abstract: A coupling between lead and extension pile segments of a driven piling. The extension segment has a formed end, an opposite driven end and a body extending therebetween. The formed end has an inner diameter equal to an outer diameter of an exposed end of the lead segment and greater than an outer diameter of the extension segment's body. The formed end has an initial length prior to coupling the extension and lead segments; the formed end undergoes secondary end forming when a driving force is applied, such that the formed end has a final length exceeding the initial length after the extension and lead segments are coupled. In some embodiments, the extension segment has an external ring portion positioned upstream of the formed end, and the exposed end of the lead segment is cold extruded into and through the external ring portion of the extension segment.

    Abstract: A wood support protection device for protecting wood supports from water damage includes a tube that defines an interior space. The tube has a top and a bottom. The top is open. The top is complementary to a lower end of a wood support. A plurality of rods is coupled to and extends substantially perpendicularly between opposing sides of the tube. A plurality of slots is positioned in the tube adjacent to the bottom. The top is configured to insert the lower end of the wood support into the interior space. The rods are configured to retain the wooden support above the bottom of the tube. The slots are positioned in the tube such that the slots are configured to drain water from the interior space. The wood support is protected from damage and rot caused by exposure of the lower end of the wood support to water.

    Abstract: The present invention provides a nodular cast iron foundation pile pipe and a method for preparing same, including following steps: (1) preparation before pipe casting: including molten iron preparation, spheroidization and coating spraying on an inner wall of a pipe mold; (2) pipe casting process: including centrifugal casting and pipe drawing; (3) annealing process; (4) finishing process. The present invention further provides the foundation pile pipe manufactured with the above-mentioned method wherein the flange and the foundation pile pipe are integrally cast or welded. In the present invention, the nodular cast iron is used as the material of the foundation pile pipe instead of Q345 steel used in the prior art. As a result, the overall strength is enhanced. The present invention possesses advantages such as corrosion resistance, long service life, low manufacturing cost, low labor intensity, short construction period and being suitable for mechanized construction.

    Abstract: A weld-on connecting element fox a pipe sheet pile wall assembly includes (1) a base end configured to be welded to a pipe pile wall member, (2) an elongate neck strip having a substantially uniform width and having a length, extending from the base end along a predetermined main assembly direction (X) to an opposite end, which length is at least five times greater than said width, and (3) a claw strip provided at the opposite end having two claw strip members that form an oval-shaped lock chamber with their free ends facing each other to form an open jaw. The claw strip is adapted to partially surround and interlock with a head strip of another, matching connecting element. The space between the two claw-strip members is at least partially filled with a malleable sealant material, installed prior to welding the connector to the pipe piles.
