A modular slab, slab system, piles and methods of use thereof are described along with specific applications and methods of manufacture. The slab or slab system may be pre-insulated and pre-finished before being assembled on site. The slab system may be advantageous to use as a replacement for traditional in-situ poured building foundations. The slab system may also have uses in other fields such as for floors, roads, bridges, pavements/side walks and other civil and structural applications.

An underground base configured for supporting an above-ground static structure that has a pair of plates each having a distal end, a proximal end, and a body portion between the distal end and the proximal end. The pair of plates are connected to each other to define a box section and a pair of flanges extending outwardly from opposing vertices of the box section. The base further has a plurality of brackets each connected to one of the plates at the proximal end, a base plate connected to the plurality of brackets, and an adjustment plate connected to the base plate via one or more adjustment fasteners. The adjustment plate is movable relative to the base plate via the one or more adjustment fasteners to adjust an orientation of the adjustment plate relative to the base plate.

A foundation support system and method of installing the foundation support system. The foundation support system includes a pier system for providing support beneath a foundation, a support member, and a heave plate attachable to a bottom surface of the foundation. The method includes driving a pier system using a ram, coupling a support member to the heave plate, and engaging the support member with the pier system.

Disclosed embodiments include a suction pile vent plug having a cylindrically-shaped body having a sealing element, a plurality of coupling features, and a handle connected to the cylindrically-shaped body. The sealing element is configured to form a watertight seal with walls of a suction pile vent into which the vent plug is installed. The plurality of coupling features are configured to engage with corresponding coupling features of the suction pile vent. The movable handle is configured to be moved into one or more locked configurations. Disclosed embodiments further include a suction pile vent having a hollow cylindrically-shaped body having coupling features. The coupling features are configured to engage with corresponding coupling features of a suction pile vent plug to thereby mechanically couple the suction pile vent plug to the suction pile vent. Disclosed embodiments further include a fluidic port that fluidically couples a suction pile to a removable fluidic coupling.

A foundation reinforcement system may include an elongated beam, a first bracket assembly and a second bracket assembly. Each bracket assembly includes a shaft receiving portion and a seat portion. The seat portion includes a plurality of protruding members that protrude upwardly therefrom. The elongated beam is disposed atop the seat portion of the first bracket assembly such that at least one of the plurality of protruding members of the bracket assembly is disposed on each of opposing lateral sides of the elongated beam. The bracket assemblies are horizontally spaced-apart from each other. The elongated beam is disposed atop the seat portion of the second bracket assembly such that at least one of the plurality of protruding members of the second bracket assembly is disposed on each of opposing lateral sides of the elongated beam.

Provided are a helical pile and a bracket module comprising the same. The helical pile includes a column body, at least a helical blade and a loading member. The column body has a fixing end, a loading end opposite to the fixing end, and a body section between the fixing end and the loading end. The helical blade is disposed on the column body between the fixing end and the loading end. The loading member is connected to the loading end of the column body and includes a flange. The ratio of the body diameter of the column body to the blade diameter of the helical blade ranges from 1:3 to 1:7. The helical pile features excellent compression bearing capacity and uplift bearing capacity due to its specific element-size ratio, and is applicable for installation in areas subject to harsh conditions or with peculiar geological features or soil conditions.

An underground base configured for supporting an above-ground static structure that has a pair of plates each having a distal end, a proximal end, and a body portion between the distal end and the proximal end. The pair of plates are connected to each other to define a box section and a pair of flanges extending outwardly from opposing vertices of the box section. The base further has a plurality of brackets each connected to one of the plates at the proximal end, a base plate connected to the plurality of brackets, and an adjustment plate connected to the base plate via one or more adjustment fasteners. The adjustment plate is movable relative to the base plate via the one or more adjustment fasteners to adjust an orientation of the adjustment plate relative to the base plate.

A system and method for securely cradling a subsea pipeline is claimed that lands on one side of the pipeline, is embedded into the sea floor, reaches under the pipeline, positions the cradling structure, and then lifts the pipeline. The system typically comprises a gravity driven pile based device, comprising a pile tower, a roller carriage assembly, and a jacking assembly that engages the roller carriage assembly and pile tower rails.

A pile is comprised of a pipe, i.e., a tube or hollow cylinder of annular cross-section, with a coextensive internal reinforcement comprised of a plurality of intersecting walls forming a plurality of vertices. Each vertex intersects the pipe. Adjacent intersections are evenly spaced around the annular cross-section. The pile is comprised of a blend of PVC and 20 to 50% (pbw) chopped strand glass fibers. A groove is cut into the pile adjacent to an end for frictional retention in a sea bed.
