Foundation integral construction components and support systems where multiple pile foundation components are incorporated into a structure system that is connected to, or otherwise part of the foundation, can further reduce the need for excavation and thus preserve existing contours and drainage properties of the land. These multiple pile foundation systems, are applicable to a wide variety of site and soil conditions and a wide variety of surface structures or buildings. The multiple pile foundation system can reduce the need for site excavation, drainage control, and soil backfill by transferring load from a portion of a structure to the ground.

A cable-stayed suspension bridge structure suitable for super long spans by comprising a horizontally arranged main bridge main beam, wherein vertical main towers are arranged at ends of the main bridge main beam, and each main tower is anchored by stay cables; a main bridge vertical support and a longitudinal elastic damping stopper are arranged at positions of the main bridge main beam close to the main tower, and the main beam is kept stable longitudinally by virtue of the geometric stiffness of the cable force of the stay cable and the longitudinal elastic damping stopper.

The present disclosure relates to reinforcement devices, systems and methods for use in constructing new structures, including post frame structures. Specifically, the present disclosure relates to reinforcement devices, systems and methods for replacing traditional wood and/or precast concrete columns utilized in building a new construction foundation, with a height adjustable foundation column assembly constructed from a corrosion resistant material. The present disclosure also relates to reinforcement devices, systems and methods useful for reinforcing existing post frame structures, particularly those with framing elements requiring repair.

An elastic wave damping structure can include a structural arrangement of at least two elements, each with an inner volume and containing a medium resistant to passage of an elastic wave. Example elements can be earth boreholes or water pylons. The structural arrangement can taper from an upper aperture to a lower aperture, the structural arrangement defining a protection zone at the upper aperture. The structural arrangement can be configured to attenuate power from the anticipated elastic wave within the protection zone relative to power from the anticipated elastic wave external to the protection zone. A grouping may include elements that form acute or obtuse angles with a direction of an elastic wave to attenuate wave power. High-value buildings or other structure in a protection zone on land or in water can be substantially shielded from seismic or water waves.

A wind power installation foundation having a cylindrical central unit, a plurality of steel carriers which are arranged radially around the central unit and which respectively have a first and a second end, and a plurality of foundation piles. The first ends of the steel carriers are fixed to the central unit so that the second ends of the steel carriers are in the form of free ends. The second free ends of the steel carriers are respectively placed on one of the foundation piles.

A Smart Caisson incorporates an expandable balloon-like body at depth under the base of a vertical piling or foundation member. The self-expanding balloon footing counteracts soil erosion by expanding to fill areas of soil recession. A pipe or through-hole in the vertical piling admits surface rainwater into the balloon footing at the same time the rainwater is contributing to sub-surface erosion. Users can actively pump water downward through the piling through-hole to fill the balloon footing during times of low rainfall or following short-duration erosion events, such as earthquakes. The through-holes are designed to capably admit cement, concrete and other fill materials without clogging or corroding. A metal mesh surrounding the balloon footing expands with the balloon, providing structure and a matrix to trap and hold shifted sub-surface earthen material and concrete previously pumped into the balloon footing. An array of sensors warns the user of sub-surface soil conditions.

An example embodiment of the present invention provides a pole cap for covering an end of a pole. The pole cap comprises a sheet that includes a central portion, a first strip, and a flap that has a slit. The central portion is configured to cover a base surface of an end of a pole. The first strip is configured to fold over an edge of the base surface and circumferentially wrap around a portion of a curved surface of the pole. The flap is configured to fold over the edge of the base surface.

A structural tensioning system for selective coupling to a pier pipe having an elongate threaded rod and a tensioning device. The tensioning device having an elongate body that is configured receive a treaded end of the threaded rod and defines a slot in a distal end portion, a pair of opposed co-axial elongate openings, and a pair of opposed passages that communicate between respective portions of the slot and respective portions of the pair of opposed co-axial elongate openings. A portion of each elongate opening is configured to receive a bolt that is mounted in the pier pipe when the tensioning device is positioned in a tensioning position and portions of the slot, the pair of opposed co-axial elongate openings and the pair of opposed passages are configured to selectively receive the bolt that is mounted in the pier pipe as the tensioning device is moved to the tensioning position.
