Abstract

The present invention is an earth-locking apparatus and an inextricably intertwined method to form an underground grid-bridge system to provide foundation support for structures such as sand silos, holding tanks, bulkheads, and power transmission lines. The earth-locking modular apparatus has locking lugs and locking channels perpendicularly connected to a plurality of vanes that extend vertically the length of the central tubular member whereby interlocking vanes are conjoined to multiple modular apparatus allowing for confined compaction of columns and blocks of soil that are then subjected to a porosity destruction process to tighten and de-water the confined soil. The method of completing the underground grid-bridge describes the utilization of the compaction apparatus designed to work in conjunction with the earth-locking modular apparatus and earth-locking compaction implements design-engineered to cause porosity destruction resulting in extreme compression of confined soil to a load-bearing capacity that will resist compression, overturning, uplifting, torsion and sheer.

Claims (22)

1. A method of building a grid system, said method comprising:

arranging a plurality of modular apparatuses at a structure site, the plurality modular apparatuses having a central tubular member having an inner bore formed along a longitudinal length and a plurality of vanes having a lateral width at least equal to a diameter of the central tubular member and extending substantially the length of the tubular member, wherein the plurality of modular apparatuses are positioned above a surface of the structure site configured to receive one or more structures erected thereon;

connecting the plurality of modular apparatuses by coupling more than two adjacent modular apparatuses of the plurality of modular apparatuses with a connector beam or the plurality of vanes with one or more locking lugs disposed on the plurality of vanes received in a corresponding locking channel of an interlock plate, wherein at least a portion of the plurality of modular apparatuses are operably coupled to more than two adjacent modular apparatuses of the plurality of the modular apparatuses

installing the plurality of modular apparatuses into the earth wherein the inner bore receives earthen formation therein;

wherein the plurality of modular apparatuses includes at least three modular apparatuses in an X-plane and at least three modular apparatus in a Y-plane, thereby forming a grid of at least three modular apparatuses by at least three modular apparatuses.

2. The method of claim 1 , further comprising a locking channel disposed on a locking channel connection plate wherein the locking channel connection plate is connected perpendicular to one or more of the plurality of modular apparatuses, thereby providing an extension of one or more of the plurality of vanes.

3. The method of claim 1 , wherein the locking lug is configured to be received in a correspondingly shaped locking channel.

4. The method of claim 1 , wherein at least one of the central tubular member and the plurality of vanes is formed from steel having a coating formed thereon.

5. A modular grid foundation system, comprising:

a plurality of modular foundation apparatuses, each of the plurality of modular foundation apparatuses comprising:

a central tubular member having a longitudinal length;

a plurality of vanes having a lateral width at least equal to a diameter of the central tubular member and extending substantially the longitudinal length of the tubular member, the lateral width extending perpendicularly from the central tubular member; and

a locking lug having a lateral width, the locking lug perpendicularly coupled to an external edge of at least one vane of the plurality of vanes;

wherein the plurality of modular foundation apparatuses are coupled one to another, in both in an x-plane and a y-plane,

wherein at least a portion of the plurality of modular apparatuses are tangentially coupled to more than two modular foundation apparatuses of the plurality of the modular foundation apparatuses.

6. The modular grid foundation system of claim 5 , wherein two or more of the plurality of vanes has a locking lug disposed on the external edge thereof.

7. The modular grid foundation system of claim 5 , wherein a locking channel is coupled with the external edge of at least one vane of the plurality of vanes.

8. The modular grid foundation system of claim 7 , wherein the plurality of vanes is four vanes, two vanes having a locking lug disposed on the external edge thereof.

9. The modular grid foundation system of claim 5 , further comprising a locking plate having one or more locking channels formed thereon, the one or more locking channels of the locking plate configured to matingly engage with one or more locking lugs of at least one modular apparatus of the plurality of modular apparatuses.

10. The modular grid foundation system of claim 5 , further comprising a locking channel disposed on a locking channel connection plate wherein the locking channel connection plate is connected perpendicular to one or more of the modular apparatuses, thereby providing an extension of one or more of the plurality of vanes.

11. The modular grid foundation system of claim 5 , wherein the locking lug is configured to be received in a correspondingly shaped locking channel.

12. The modular grid foundation system of claim 5 , wherein at least one of the central tubular member and the plurality of vanes is formed from steel having a coating formed thereon.
