  • Publication number: 20140255106
    Abstract: A perimeter pile anchor foundation is built by forming a plurality of individual perimeter pile anchors in a large generally circular pattern to form a perimeter wall. The individual pile anchors are contiguous, each pile overlapping the adjacent piles on either side. The overlapping pile anchors form an arch such that compression and friction between the pile anchors resist soil caving and sloughing pressure when soil inside the perimeter wall is excavated, enabling the perimeter pile foundation to be effectively constructed in weak saturated soils and/or cohesionless sands that will not allow conventional concrete foundation excavations. A concrete foundation ring is formed inside the pile perimeter wall to support a tall and/or heavy tower or other structure subject to high upset forces.

    Abstract: The disclosure describes, in part, apparatuses and methods for installing structures (e.g., foundations, footings, anchors, abutments, etc.) at work sites, such as difficult-access work sites. In some instances, a rotating drill assembly is assembled over a target location in order to excavate a radial array of batter-angled shafts associated with the target location in preparation for the installation of a radial array of micropiles. An operator utilizes the rotating drill in combination with a foundation pile schedule/decision matrix to design and install the radial array of batter-angled micropiles. This disclosure also describes techniques for designing, fabricating and installing structural caps to be coupled to the installed radial array batter angled micropiles. These structural caps are lightweight and, thus, more portable to difficult-access sites where they are coupled to the micropiles forming a foundation for structure to be installed at the difficult-access site.

  • Patent number: 6641333
    Abstract: The present application relates to a method of installing a pre-cast pile in the ground which involves applying an enlarged head forming tool to the ground until a volume of soil has been displaced or removed so as to form a void at the surface of the ground. The pre-cast pile is then driven into the ground to a predetermined depth below the void and the void is then filled with concrete or grout to form a cast-in-situ pile head. The diameter of the pile head is greater than the diameter of the pile shaft.

  • Patent number: 6543967
    Abstract: Pilings are installed for leveling a foundation. A first segment is driven into the ground. Then two support rods of varying length are positioned and grouted into a passage running through the segment. The first support rod is one-half of the height of the piling segment, while the second is one and one-half times the height of the piling segment. An additional piling segment is driven on top of the first segment. Support rods which are twice the height of a single segment are positioned and grouted into the passage. This process is repeated until the assembly is the required depth.

  • Patent number: 6394703
    Abstract: A method and apparatus for forming a capping beam across two or more cast-in-situ piles (11), wherein a precast or preformed guide wall structure (1) having holes (5) for receiving and guiding a piling auger is placed into an excavation, forming a number of cast-in-situ piles (11) by applying a piling auger to the ground through the holes (5) in the guide wall structure (1), removing the guide wall structure (1) and filling the excavation with concrete so as to form a capping beam. This results in much improved construction times, since it is not necessary to remove excess hardened concrete before forming the capping beam, and also results in less waste, since the guide wall structure can be reused.

  • Patent number: 6241426
    Abstract: A method is provided for forming an interconnected underground structure which avoids settling of adjacent soil structure. A plurality of underground support columns is initially formed, with the support columns being spaced apart in a predetermined pattern. Interconnecting holes are thereafter formed between the underground support columns, wherein the interconnecting holes are formed by mechanically cutting the soil and simultaneously hydraulically mixing the mechanically cut soil with slurry injected at velocities of 200 feet per second or higher while maintaining a positive hydrostatic head in the hole relative to adjacent soil. As the interconnecting holes are being formed, the diameter of each interconnecting hole is extended by positioning a second high velocity slurry nozzle near the outer diameter of the interconnecting hole which injects high velocity into the adjacent soil to hydraulically cut the adjacent soil and mix it with the slurry.

  • Patent number: 6123485
    Abstract: Fiber reinforced plastic FRP formed about concrete piles and columns. The FRP components generally includes an exterior shell and an interior protruding portions. The concrete filled FRP tubes are enhanced by prestressing the concrete core, thereby increasing the bond with the tube and placing the tube in an active hoop tension. The prestressing can be developed by either post-tensioning a series of strands(or tendons) that are placed inside the core, or by using expansive core materials which do expand upon curing and will therefore impose an active pressure on the confining tube. The bond can be developed by either internal resin grids, FRP spirals, FRP orthotropic grids, sand-resin coating, bonding agent or protruded ribs. The system can be used as a fender pile, bearing pile, bridge pier column, or any structural column. The system can be made by pultrusion, SCRIMP, REM, centrifugal methods or hand lay-up.
