A concentrically loaded foundation pier system which includes several concentrically stacked steel pipes filled with concrete. The entire pier is installed centrally beneath the footing of the structure. Shims are placed between the top-most pier element and a pier cap which prevents shifting when the soil expands and contracts. The final structure is end-loaded and pressed to the bedrock or other load-bearing strata. An alternative embodiment includes a temporary lifting assembly which can be fastened about the structural pier without need for bolts or other fasteners.

A foundation system for the foundation of an offshore structure includes a monopile having an anchoring portion anchorable in a seabed and a connection portion disposed at the opposite end. A platform structure is connected directly to the connection portion of the monopile or indirectly via a transition piece. The platform structure is disposable above a water surface. The foundation system includes at least two stabilizing devices connected directly to the platform structure or indirectly to the platform structure via the transition piece. The stabilizing devices are attachable to the seabed such that tensile forces or compression forces are transmittable between the seabed and the platform structure. Securing points on the stabilizing devices, together with the connection portion of the monopile, define a plane having a horizontally extending component.

Disclosed is a multiple friction joint pile connection construction system to construct: shallow and deep foundations for structures, tie beam construction between footings, passive piles to prevent slope failures beam on elastic foundation, pile cap and tie beam in the construction of pile groups, load transfer platforms isolated (not connected) from the upper structure, retaining structure when constructed with vertical and horizontal orientation, vertical and horizontal drain when perforated blocks are used, landing pier, quay wall and platform construction for coastal and harbor structures, by anchoring to the upper section of the existing bored piles, by anchoring to the upper sections of the columns of the upper structure, in railroad tie manufacture, in transportation structures and in all kinds of similar geotechnical applications.

This disclosure relates to the design of pile cap assemblies configured to rotatably couple the torque tube of a photovoltaic solar tracker to multiple support piles that elevate the torque tube above the ground. The pile cap assemblies define low friction bearings that allow the torque tube to rotate smoothly within the low friction bearings. The pile cap assemblies also include numerous mounting hole configurations that allow for adjustment of a position of the pile cap assemblies with respect to the support piles. This allows for any small variation in positioning of the support piles to be accommodated.

The invention relates to a foundation for a wind turbine, wherein the foundation comprises substantially prefabricated elements, preferably made of reinforced concrete, with a first, vertically extending base-like portion, on which a tower of the wind turbine can be arranged, and a second substantially horizontally extending portion as foundation body, which is in contact with the ground. The first portion is arranged above the second portion and has at least one closed, preferably sleeve-shaped, base element, which is annular or polygonal, and the second portion is formed from at least two horizontal elements, which each have at least one base portion. The at least one base element of the first portion and the base portion of the horizontal element of the second portion have substantially vertical apertures, which are mounted in line with one another and in which substantially vertical bracing elements, preferably threaded rods, are arranged. The at least one base element of the first portion and the at least two horizontal elements of the second portion are preloaded against one another by the substantially vertical preloading elements. No further fastening means, in particular horizontal fastening means, are necessary for dissipation of the loads from the wind turbine.

A pile (270) within a bore (110) comprises a column (250). The column (250) comprises a stack of a plurality of pile sections (300) arranged end-to-end within the bore (110). There is a cured material (260) between at least a part of an outside surface of the column (250) and the surface of the bore (110). The cured material, for example grout, may be provided through channels in the pile sections.

The invention relates to a profiled connection section with a constant cross-section for coupling at least two Larssen sheet piles (Sx, Sy, Sz) at an angle of 90°, comprising two identically designed hooked strips (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106).
