Responsive to the difficulties encountered in recycling, disposing of, and repurposing spent tires, as well as the need for durable construction materials, concentric tire structures and methods for making the same are provided herein.

In a general aspect, a method is presented for manufacturing support structures for offshore wind turbines. In some implementations, the method includes constructing a plurality of modular sections that assemble to define the support structure. One or more of the plurality of modular sections are configured to anchor to an underwater floor. At least one of the plurality of modular sections is constructed by operations that include forming a wall along a perimeter to bound a volume, filling the volume with a castable material, and hardening the castable material. In some instances, forming the wall includes depositing layers of printable material successively on top of each other. The method also includes joining the plurality of modular sections to assemble the support structure.

The present disclosure relates to inventions which may improve the construction of structures of various sizes, including houses, porches, patios, and the like. The disclosed embodiments provide advantages over concrete foundations. For example, disclosed embodiments may provide a base and a beam which can replace a concrete foundation, thereby facilitating easier construction while maintaining required structural integrity. The base and beam may be formed of metal and coated in corrosion resistant plastic. Moreover, a cap may be attached to the beam, where the cap provides an interface for attaching a structural support beam.

A foundation for a wind mill includes a circular or polygonal pedestal for supporting a wind mill tower and a plurality of ribs radiating radially outwardly from the pedestal, wherein the pedestal is divided into a plurality of circumferential sections, wherein a circumferential section and a rib are each integrally formed with one another, or are each formed, as a precast concrete element, wherein the precast concrete elements are made from reinforced concrete including a first reinforcement structure, in particular reinforcement bars, embedded into the precast concrete elements, neighbouring precast concrete elements, in their sections radiating outwardly from the pedestal, are spaced from each other in a circumferential direction and the clearance between two neighbouring precast concrete elements is each bridged by a bridging plate.

Reinforcement assemblies, reinforcement fixtures, methods of constructing a reinforcement assembly, and methods of constructing a reinforcement fixture are described herein. An example embodiment of a reinforcement assembly comprises a plate, a plurality of connectors, and a plurality of elongate members. The plate comprises a plate lengthwise axis, a plate center axis, a plate top surface, a plate bottom surface, and a plate outer surface. Each connector of the plurality of connectors is attached to the plate outer surface and each elongate member of the plurality of elongate members is attached to a connector of the plurality of connectors.

The present invention relates to the field of bioinspired geotechnics to provide an alternative to conventional vertical and inclined skirted footings and their method of installation. The invention provides tree root inspired substructure with improved load carrying capacity and a method of installation. Tree root inspired substructure herein defines a square or rectangular or circular or strip footing with closely spaced vertical/inclined micropiles. This hybrid substructure takes advantage of depth effect, width effect, arching effects, compaction and relative ease in installation on level and sloping grounds as compared to conventional skirt/bucket foundation. The micropiles attached to the traditional footing are spaced such that the trapped soil in-between behaves as a plug and major load shearing/transfer takes place at the level of tip of micropiles. Some load distribution also takes place along the micropiles and underneath the footing. The uplift, moment, lateral and vertical load carrying capacity gets enhanced due to the increase in the depth of foundation without much efforts on excavation. The proposed foundation can be cast-in-situ or precast or hybrid. Micropiles of the footing could be installed by either driving or boring. Micropile material can be solid/hollow steel or reinforced/unreinforced concrete, while the footing can be made up of steel plate/frame or reinforced/prestressed concrete. Appropriate selection of a bioinspired skirted footing saves a lot of material and construction time as compared to conventional skirted footing, leading to cost savings.

A method for the construction of an improved tank base. A tank base is constructed for protection against accidental spills and/or leaks associated with a tank battery. The improved tank base comprises at least one part of a suitable substrate, which allows for the adhesion of an elastomer such as polyurea. Polyurea is preferably applied using a spray device which yields an average coverage of about 50-80 mils, and most preferably 60 mils. If more than one substrate is used, one or more substrates can be bound together with a fastening system. Once pressure is applied in the form of weight, the fastening system can be removed, resulting in an improved tank base having at least one seam and impervious to the fluid of the tank battery.
