A grout plug assembly for use in forming a pipe pile system defining at least one pile assembly inner surface portion comprises a resiliently deformable plug body and a substantially rigid plug cap. The resiliently deformable plug body defining a plug outer surface, a plug inner surface, a first plug end surface, a second plug end surface, where the plug inner surface defines a plug passageway. The substantially rigid plug cap defines a cap outer surface, a cap inner surface, a first cap end surface, and a second cap end surface. The second cap end surface is rigidly secured to the first plug end surface. The plug outer surface is sized and dimensioned to engage the at least one pile assembly inner surface portion of the pipe pile system during formation of the pipe pile system.

Disclosed is a joint for connecting first and second elongate members together end to end, the joint comprising: a first connecting structure and a second connecting structure at an opposed end of the second elongate member; one of the first and second connecting structures comprising at least one male connector unit having a longitudinally projecting male part which is tapered in the longitudinal direction; the other of the first and second connecting structures having at least one female connector unit defining a correspondingly tapered recess into which the male part is received; the other of the first and second connecting structures defining lateral locking pin holes aligned either side of the recess and the male part having a corresponding lateral locking pin hole; and a locking pin insertable through the corresponding locking pin holes.

A foundation support apparatus is provided and includes a tubular piling with a rib of material fixed to an exterior or outer surface of the piling. The rib provides improved total resistive force capabilities for the support apparatus, as compared to a bare piling. The rib is positioned and dimensioned as to not impede the installation of the piling. The rib may be circular or helical, continuous or discontinuous, and is disposed coaxial with a longitudinal axis of the piling. The foundation support apparatus may be manufactured on a construction site to readily improve the load capacity of various types of vertical foundational systems, such as driven pilings. The foundation support apparatus may be encased or backfilled with grout materials which harden around the ribs of the apparatus forming an interlocking engagement between the grout and the ribs, thereby increasing load resistance capabilities of the support apparatus.

Provided is a support structure and a method for manufacture thereof. The support structure, in one aspect, includes first and second expanded metal structural pillars positioned within the ground by a distance (d.sub.1), the first and second expanded metal structural pillars comprising a metal that has expanded in response to hydrolysis. In at least one other aspect, the support structure includes one or more beams spanning the first and second expanded metal structural pillars.

Embodiments of the present disclosure generally relate to a pumping unit base and methods for operating with the pumping unit base. The pumping unit base may include a plurality of driven piles installed in the ground, and a metal platform fixedly attached to the plurality of driven piles, wherein the metal platform is positioned above the ground. The metal platform may be removed from the driven piles and reinstalled to the driven piles.

A foundation support system and method of installing the foundation support system. The foundation support system includes a pier system for providing support beneath a foundation, a support member, and a heave plate attachable to a bottom surface of the foundation. The method includes driving a pier system using a ram, coupling a support member to the heave plate, and engaging the support member with the pier system.

A pile segment for building supports to level foundations, e.g., slabs, has a generally cylindrical body made of concrete, the outer vertical surface of the cylindrical body being comprised of alternating spaced crests and troughs.

A foundation component having an elongated shaft with a below-ground end and an opposing above-ground end. The foundation component is installed by sleeving it over a mandrel and applying downward force to the mandrel to insert the component and mandrel into underlying soil. Proximate to the underground end, the shaft has one or more crumple zones formed along its length. When the mandrel is rotated to a locked position and upward force is applied while bracing the above-ground end of the component, one or more of the crumple zones expand transversely into the soil, depending on the soil's density, thereby increasing the component's bearing capacity and resistance to pull out.

Embodiments of the present disclosure generally relate to a pumping unit base and methods for operating with the pumping unit base. The pumping unit base may include a plurality of driven piles installed in the ground, and a metal platform fixedly attached to the plurality of driven piles, wherein the metal platform is positioned above the ground. The metal platform may be removed from the driven piles and reinstalled to the driven piles.

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.
