Abstract

A method of forming a structure includes a) excavating a material; b) homogenizing the material; c) ensuring aluminosilicate levels in the material; d) increasing alkaline levels of the material; e) foaming the material; and f) injecting the material onto a surface, wherein the material forms into a foam-like structure when injected.

First claim

The invention claimed is:

1. A method of forming a structure, the method comprising:
a) excavating a material;
b) homogenizing the material;
c) ensuring aluminosilicate levels in the material;
d) increasing alkaline levels of the material;
e) foaming the material; and
f) injecting the material through a mouth of an injection tube, the mouth submerged under water so that the material is injected through the water to settle onto a surface that is under water, wherein the material forms into a foam-like structure and solidifies under water when injected.

2. The method of claim 1 , wherein step b) further comprises:
analyzing the water content of the mixture; and

adjusting water levels for the mixture by adding or eliminating water from the mixture.

3. The method of claim 1 , wherein step d) comprises adding an alkaline material.

4. The method of any of claim 1 , wherein step c) comprises adding a binder material to the mixture.

5. The method of claim 4 , wherein the binder material comprises fly ashes, blast furnace slag, calcined clays, waste glass, waste stone and/or rock wool.

6. The method of claim 1 , wherein one or more steps of the method are performed using a dosing system.

7. The method of claim 1 , wherein step e) comprises:
mechanically mixing air into the material or pressurizing the material and adding compressed air to the material.

8. The method of claim 1 , wherein step e) comprises:
adding a foaming agent into the material.

9. The method of claim 1 , wherein step e) comprises:
adding a metal powder to the material.

10. The method of claim 8 , and further comprising:
adding a catalytic ignition agent to the material.

11. A reclamation system comprising:
means for excavating a material;
a mixing system for forming a mixture with the material, the mixing system further able to homogenize the mixture, ensure correct aluminosilicate levels in the mixture, and/or increase alkaline levels in the mixture; and
an injection system comprising an injection tube with an injection mouth, wherein the injection mouth is submerged under water for injecting the mixture under water onto a surface that is under water, wherein the mixture forms into a foam-like structure and solidifies under water once injected.

12. The reclamation system of claim 11 , wherein the injection system further comprises means for mechanically mixing air into the mixture, means for adding a foaming agent into the mixture, means for adding a metal powder and a catalytic ignitor and/or means for pressurizing the mixture and adding compressed air into the mixture.

13. The reclamation system of claim 11 , wherein the mixing system comprises an analysis system to analyze the content of the mixture and/or adjust water levels of the mixture.

14. The reclamation system of claim 13 , wherein the analysis system can continuously detect and/or adjust the levels of water, material, binder, metal powder, foaming agent and/or other additives in the mixture.

15. The reclamation system of claim 11 , and further comprising a dosing system for injecting the material, binder, metal powder, foaming agent, water and/or other additives into the mixing system.

16. The reclamation system of claim 11 , wherein the mixing system ensures correct alkaline levels in the mixture by adding an alkaline material and ensures correct aluminosilicate levels in the mixture by adding a binder.
