Claims
- 1. A multi-sectioned concrete support structure, comprising:a first concrete section comprising a first concrete type, the first concrete section having a first surface attached to a load bearing surface and a second surface; and a second concrete section comprising a second concrete type, the second concrete section having a first surface attached to the second surface of the first concrete section and a second surface coupled to the load, wherein an internal cavity is formed along the center load line between the first and second surfaces of the second concrete section, and wherein the internal cavity is filled at least partially with a third concrete type.
- 2. The multi-sectioned concrete structure of claim 1, wherein the first concrete type comprises standard grade concrete.
- 3. The multi-sectioned concrete structure of claim 1, wherein the second concrete type comprises silica-mixed concrete.
- 4. The multi-sectioned concrete structure of claim 3, wherein the first and third concrete types each comprise standard grade concrete.
- 5. The multi-sectioned concrete structure of claim 4, wherein the load bearing surface comprises a seabed.
- 6. A method for manufacturing a multi-sectioned concrete support structure, the method comprising:providing a first concrete section comprising a first concrete type; providing a second concrete section comprising a second concrete type, wherein the second concrete section includes an internal cavity extending along the center load line of the second concrete section; attaching the first concrete section to the second concrete section; and filling, at least partially, the internal cavity of the second concrete section with a third concrete type.
- 7. The method of claim 6, wherein the first concrete type comprises standard grade concrete.
- 8. The method of claim 7, wherein the second concrete type comprises silica-mixed concrete.
- 9. The method of claim 8, wherein the third concrete type comprise standard grade concrete.
- 10. The method of claim 9, wherein the process of providing a first concrete section further comprises:embedding a water-impermeable sleeve into a load bearing surface; and excavating, to a predefined depth, the area contained within the sleeve.
- 11. The method of claim 10, wherein providing a first concrete section comprises pouring concrete into the excavated area.
- 12. The method of claim 10, wherein providing a first concrete section comprises lowering a concrete portion through the water-impermeable sleeve into the excavated area.
- 13. The method of claim 10, wherein providing a second concrete section comprises lowering, through the water-impermeable sleeve, a pre-cast concrete section on top of the first concrete section.
- 14. The method of claim 13, wherein the outer dimension of the pre-cast concrete section closely approximates the inner dimension of the water-impermeable sleeve.
- 15. The method of claim 13 wherein the outer dimension of the pre-cast section is substantially less than the inner dimension of the water-impermeable sleeve.
- 16. The method of claim 10, wherein providing a second concrete section comprises pouring, through the water-impermeable sleeve, silica-mixed concrete on top of the first concrete section.
- 17. The method of claim 10, wherein the load bearing surface comprises a seabed having a new bay mud layer, an old bay mud layer, and a bed rock layer, wherein embedding a water-impermeable sleeve into a load bearing surface comprises embedding the water-impermeable sleeve into the new bay mud layer of the seabed.
- 18. The method of claim 10, wherein the load bearing surface comprises a seabed having a new bay mud layer, an old bay mud layer, and a bed rock layer, wherein embedding a water-impermeable sleeve into a load bearing surface comprises embedding the water-impermeable sleeve into the old bay mud layer of the seabed.
- 19. The method of claim 10, wherein the load bearing surface comprises a seabed having a new bay mud layer, an old bay mud layer, and a bed rock layer, wherein embedding a water-impermeable sleeve into a load bearing surface comprises embedding the water-impermeable sleeve into the bedrock layer of the seabed.
- 20. A system for manufacturing a multi-sectioned concrete support structure, the method comprising:means for providing a first concrete section comprising a first concrete type; means for providing a second concrete section comprising a second concrete type, wherein the second concrete section includes an internal cavity extending along the center load line of the second concrete section; means for attaching the first concrete section to the second concrete section; and means for filling, at least partially, the internal cavity of the second concrete section with a third concrete type.
