Cellular and ballasted universal pole foundation
View Patent ↗A volumetric enclosure or enclosures and/or a cellular structure pole foundation is provided. The volumetric enclosure/s or cellular structure pole foundation may employ several embodiments: (1) a single or a plurality of volumetric enclosures at the vertical center of the foundation below the foundation's pole cavity; (2) a single or a plurality of volumetric enclosures at the vertical center of the foundation below the foundation's pole cavity and a cellular structure within the foundation walls and base; (3) a cellular structure throughout the entire body of the foundation; (4) a cellular structure within the foundation walls; (5) the above embodiments with fill material consisting of gas or fluid or solids retained inside the foundation walls; and (6) the above embodiments with solid fill material that can reach the foundation core through the pole cavity.
1. A pre-fabricated pole foundation comprising:
a monolithic pole foundation having a foundation structure having in part or in whole one or more cellular enclosures, one or more volumetric enclosures or one or more cellular and volumetric enclosures, wherein the monolithic pole foundation comprises:
a pole retaining cavity surrounded by a cavity internal wall with a dedicated through opening extending through the cavity internal wall at a bottom of the cavity;
a pole anti-rotation device, a pole uplift prevention device or a pole anti-rotation and uplift prevention device; and
conduits for power or power and data cables entry into the pole retaining cavity.
2. The pole foundation of claim 1 , further comprising embedded power or power and data conduits, power or power and data enclosures, or power or power and data conduits and enclosures embedded in walls of the pole foundation formed as part of the monolithic pole foundation.
3. The pole foundation of claim 1 , wherein a pole foundation cavity wall comprises at least one spout for entry of or evacuation of a fill substance formed of fluid, gas or solids into the pole foundation structure interior.
4. The pole foundation of claim 3 , wherein at least one cavity of the cellular enclosures, volumetric enclosures or cellular and volumetric enclosures inside the foundation structure retains the fill substance to act as foundation ballast.
5. The pole foundation of claim 4 , wherein the fill substance is changeable in state in response to coming in contact with air, an admixture or air and an admixture.
6. The pole foundation of claim 1 , further comprising a pole cap, wherein the pole cap centers the pole vertically within the pole cavity.
7. The pole foundation of claim 6 , wherein the pole cap couples the pole to the foundation and inhibits pole rotation and uplift.
8. The pole foundation of claim 1 , wherein the cellular enclosure, the volumetric enclosure or the cellular and volumetric enclosure is formed of metallic or non-metallic material or a combination thereof.
9. The pole foundation of claim 1 , wherein the cellular enclosure, the volumetric enclosure or the cellular and volumetric enclosure is free of metallic reinforcing.
10. The pole foundation of claim 1 , wherein the pole foundation is configured to receive and retain straight shaft poles and tapered shaft poles of different cross-sectional profile, size and material.
