  • Patent number: 7707797
    Abstract: A circular concrete cap foundation poured in-situ within a perimeter forming corrugated metal pipe set atop or within an excavated pit and enclosing a series of circumferentially spaced pile anchors. The circular concrete cap foundation supports sets of inner and outer circumferentially spaced tower anchor bolts having their lower ends anchored to an embedded anchor ring and their upper ends projecting vertically and upwardly out the top of the circular foundation to engage the base flange of a supported tower. The pile anchors are formed with perimeter corrugated metal pipes set deep in subsurface soils with cementitious material surrounding and partially bonding to a centralized steel bolt or tendon which extends through the cap foundation. The tower anchor bolts and the pile anchor bolts are both partially encased in a PVC sleeve so that the bolts can be post-tensioned. The pile anchors are in tension only and serve to pull the cap foundation down to compress the underlying ground soils.

  • Patent number: 7021866
    Abstract: The invention is an article of manufacture that has for its purpose, the anchoring of a pole, tube or rod in sand or other sediments. The principal anchoring element is a broad flange auger having a receptacle mounted on top of the auger for insertion of the bottom portion of the pole, tube, or rod, which is to be supported by the anchoring device. When not in use, and during transport to the location of use, the auger is covered by a tubular sheath, which covers the auger up to the receptacle on top, as a protection against the sharp edges of the auger. When removed from the auger, the sheath is used as a handle for turning the auger by use of a locking system that attaches the sheath or handle to the receptacle at the top of the auger. As the handle turns the auger, the auger penetrates the sediments, providing a stable anchor for the pole, tube, or rod. The round pointed end of the sheath may also be used for creating a starter hole in the beach sand or ground surface to begin the operation of the auger.

    Abstract: A circular concrete cap foundation poured in-situ within a perimeter forming corrugated metal pipe set atop or within an excavated pit and enclosing a series of circumferentially spaced pile anchors. The circular concrete cap foundation supports sets of inner and outer circumferentially spaced tower anchor bolts having their lower ends anchored to an embedded anchor ring and their upper ends projecting vertically and upwardly out the top of the circular foundation to engage the base flange of a supported tower. The pile anchors are formed with perimeter corrugated metal pipes set deep in subsurface soils with cementitious material surrounding and partially bonding to a centralized steel bolt or tendon which extends through the cap foundation. The tower anchor bolts and the pile anchor bolts are both partially encased in a PVC sleeve so that the bolts can be post-tensioned. The pile anchors are in tension only and serve to pull the cap foundation down to compress the underlying ground soils.

  • Patent number: 6705053
    Abstract: An apparatus and a method are provided for lifting and leveling an existing building from a position underneath the existing building. At least a first non-cylindrical support section having a substantially rectangular shape and first and second ends is located within the earth at a position underneath the existing building. A cap support section is placed in contact with the second end of the first non-cylindrical support section. A jack is disposed on the upper side of the cap support section and raised until the foundation of the existing building has been lifted to a desired height. The non-cylindrical support section has low bearing and high friction characteristics. The low bearing characteristics enable the apparatus to be driven further into the earth than cylindrical pilings that are commonly used to lift and level existing buildings. The high friction characteristics assist in maintaining the stability of the apparatus once it has been installed.

  • Patent number: 6682267
    Abstract: A piering device includes a shaft having a polygonal cross-section with a series of notches spaced at intervals along the vertices of the shaft. For example, the shaft can have a square cross-section with rounded corners. The helical plate has a passageway with a cross-section to slide along the shaft when the helical plate is in a first rotational position on the shaft. However, notches within the passageway of the helical plate engage the notches on the shaft when the helical plate is rotated to a second rotational position, thereby preventing the helical plate from sliding along the shaft. A key is inserted between the shaft and helical plate to hold the helical plate in the second rotational position and thereby fix the axial position of the helical plate on the shaft.
