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.

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 pier for a solar tracking system includes a bearing housing assembly and a frame defining a A-shaped profile having a pair of legs and a crown interposed between the pair of legs, the frame including a pivot disposed on the crown and extending between the pair of legs, the pivot configured to support the bearing housing assembly.

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 interlocking 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 for 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.

Contemplated are simplification and cost reduction in arrangement of connecting a pair of steel pipes to each other. A joint mechanism for a pair of steel pipe piles 1A, 1B includes an inner joint 10A provided in the steel pipe pile 1A, an inner joint 10B, an outer joint 20 disposed circumferentially between and across the inner joint 10A of the steel pipe pile 1A and the inner joint 10B of the steel pipe pile 1B, and a key member 30 configured to prevent relative movement between the pair of steel pipe piles 1A, 1B in a longitudinal direction of these steel pipes 1. The outer joint 20 includes an opening portion 22 (22A, 22B) for inserting, from its outer circumferential face, split key members 31 constituting the key member 30 into a key groove constituted of an outward circumferential groove 13 (13A, 13B) provided in the outer circumference of the inner joint 10A and the inner joint 10B respectively and an inward circumferential groove 23 (23A, 23B) provided in the inner circumference of the outer joint 20 in opposition to the outward circumferential groove 13 (13A, 13B).

A driven pile comprising a substantially cylindrical shaft, wherein the shaft provides a first pile end and a second pile end, wherein a socket is arranged on the driven pile in the region of the second pile end, wherein the socket or the driven pile has an abutment in the region of the second pile end so that a further driven pile can be inserted with a first pile end as far as a maximum insertion depth defined by the abutment, wherein the socket and/or the driven pile in the region of the second pile end provides or provide in the interior at least one undercut portion extending at least substantially to the abutment.

A foundation support system includes a hollow foundation support shaft formed with a first axial length and a first torque transmitting distal end edge including an asymmetric torque transmitting tooth. The asymmetric torque transmitting tooth includes a forward torque transmitting edge portion and a rearward force transmitting edge portion opposing the forward torque transmitting edge portion. The forward torque transmitting edge portion and the rearward torque transmitting edge portion have a respectively different shape and orientation on the first torque transmitting distal end edge.

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.
