The present invention relates to a pile foundation including: a pile that extends in a vertical direction, and whose pile head protrudes above the ground, and that supports a tower-type structure, and ribs that are provided at the pile in a vicinity of a surface of the ground, and that protrude outwardly in radial directions from an outer circumferential surface of the pile.

Improved masts for solar pile driving machines are provided that incorporate inline drilling as well as alignment and assembly devices that enable greater positional accuracy than possible with conventional equipment. In some cases, a jig, holder, or other device on the mast of the machine can be used to place a bearing assembly for a single-axis tracker while the foundation is being installed. Also disclosed are various multi-piece foundation piles that enable positional adjustment between below and above-ground components to compensate for misalignment.

A foundation system for manufactured homes, prefabricated houses, and other structures. Multiple screw anchors are driven into the ground at the desired location of the structure. Preformed grade bars may be placed over the screw anchors to provide a modular foundation without pouring concrete or digging footers. Alternatively, adapters may be attached to one or more of the driven screw anchors to provide a pedestal to receive the grade bar or prefabricated sections of concrete

Systems and methods for constructing concrete foundations are provided which allow for rapid and high-precision placement and alignment of anchor bolts across large distances. A frame system is constructed outside of an excavation and then suspended, using supports, over an excavation. The frame system can include a frame having one or more templates for anchor bolts, a form suspended from the frame, and a mat and cage assembly tied to the frame. The frame system can be aligned in proper position and the anchor bolts placed in the frame system before the concrete is placed. In this way, the anchor bolts can be cast in place as the footing is placed.

The present invention is a barrier wall comprising: a foundation, wherein the foundation has a plurality of extensions protruding from one side of the foundation; a set of lower buttress walls positioned along each of the extensions; a first deck positioned on the first set of lower buttress walls; a set of upper buttress walls positioned along the decks upper surface; a second deck positions on the second set of upper buttress walls; and a front wall positioned to substantially cover the set of lower buttress walls, the lower deck, the set of upper buttress walls, and the upper deck.
