A tip is described which extends axially along a central longitudinal axis and is configured to displace the ground when the tip is being rotated about its central longitudinal axis during a ground displacement operation for a foundation pile. The tip comprises a tip body; several spiral-shaped ribs protruding from the tip body; and several protrusions arranged to the ribs. The protrusions comprise a point which is arranged such that, during rotation of the tip about its central longitudinal axis, the point of the protrusion is ahead of the rib to which the protrusion is arranged. The tip body, the ribs and the protrusions are made as a single-piece casting.

A bearing pile including a plurality of connected corrugated steel shells inserted into a subsoil and installation methodology of the same.

Foundation for a tower of a wind turbine with at least three columns. The foundation includes a reinforced concrete pile corresponding to each of the tower columns. According to one embodiment the pile includes a bolt cage and a main reinforcement formed by a cylindrical framework made up of horizontal rings interconnected by vertical bars. The bolt cage is arranged inside the main reinforcement radially at a distance of less than 0.1 meters. Each of the piles resides in a hole formed in the ground. Concrete is not poured into the holes until the main reinforcements and bolt cages are placed therein and aligned with one another.

A system for and method of stabilizing rail track structures using a load transfer apparatus is disclosed. The load transfer apparatus includes a vertical load transfer element and a top load transfer element, wherein the top load transfer element is used to transfer applied locomotive and rail car loads to the vertical load transfer element. In one embodiment, the top load transfer element includes helical flights. In another embodiment, the top load transfer element includes a flared top. In yet another embodiment, the top load transfer element includes a load transfer cap. In a further embodiment, the top load transfer element includes two or more support legs each with a top support attached thereto. The railroad stabilization system can comprise any one type or any combinations of types of the aforementioned load transfer apparatuses.

A photovoltaic solar panel array support structure that has a negligible footprint and that may be adjustably sized in the future to accommodate an increase or decrease of the number of solar panel arrays. It is installed at a substantial elevation above ground level so as to allow unhampered, ongoing farming activities in the area directly below the solar panel array, including the use of large mechanized farm equipment. The photovoltaic solar panel array support structure utilizes a series of vertical pilings that support a pre-fabricated unitary segment platform upon which a solar panel system may be mounted and then lifted atop of the pilings as a single assembly. It is intended for erection and operation in locations where large-scale ground mounted solar panel arrays are not feasible.

A seismic wave damping structure can include a structural arrangement including at least one pair of elements, each angled with respect to a vertical and extending into the earth and toward a protection zone. The elements thus form a tapered aperture, the structural arrangement defining the protection zone at an upper portion of the aperture. Each element defines an inner volume and contains a medium resistant to passage of an anticipated seismic wave in earth having a wavelength at least one order of magnitude greater than a cross-sectional dimension of the inner volume of each of the elements. The medium is at least one of air, gas, water, and viscous fluid. The structural arrangement is configured to attenuate power from the anticipated seismic wave within the protection zone relative to power from the anticipated seismic wave external to the protection zone.

A foundation pier bracket system provides attachment of a pier shaft with a building or structure foundation such that the system provides securement to competent strata or soil below. The system can include a reinforcing sleeve and a bracket assembly. The bracket assembly can include a shaft receiving portion and a seat portion. The shaft receiving portion can define an aperture that is sized and shaped to receive a portion of the reinforcing sleeve therein. The seat portion can include a plurality of protruding members that protrude upwardly therefrom. The plurality of protruding members can be arranged such that they restrain lateral movement of a beam along the seat portion in at least one axis. The reinforcing sleeve can include a locking wedge that secures the reinforcing sleeve to the bracket assembly. A method of supporting a foundation of a building is also provided.

A multiple-part pile cap can include a top portion and a bottom portion that are configured to supply a mechanical interface between a first foundation pile providing a foundation for a structure and a frame of a structure itself. The multiple-part pile cap can be installed onto the first foundation pile of a set of foundation piles driven into the ground to provide the foundation for the structure using the multiple-part pile cap as the mechanical interface between the first foundation pile and the frame of the structure being secured to the first foundation pile. The bottom portion of the multiple-part pile cap can be i) matched in width to a width of a webbing of the first foundation pile and ii) has one or more holes in a first flange of the multiple-part pile cap to be bolted to the webbing of the first foundation pile.
