Abstract
Abstract A method for forming a grout composition from multiple components. A first component is mixed in pre-measured amounts along with water in a first mixing tank. A first catalyst is added in pre-measured quantities to the first mixing tank. A second catalyst is mixed in pre-determined quantities with water in a second mixing tank. The aqueous solutions in the first and second mixing tanks are combined to cause a polymerization-cross-linking reaction of the first component which results in gellation of the first component.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A method for forming a grout composition from multiple components comprising the steps of: placing a pre-determined quantity of a first component in a water soluble container; mixing a pre-determined number of the water soluable containers containing the first component with water in a first mixing tank; mixing a pre-determined quantity of a first catalyst with the water and the first component in the first mixing tank; mixing a pre-determined quantity of a second catalyst with water in a second mixing tank; and combining the solutions within the first and second mixing tanks to cause a polymerization-cross linking reaction of the first component such that the first components solidify.
Claim 2
Independent Claim
109 words
A method for forming a grout composition from multiple components comprising the steps of: placing a pre-determined quantity of a first component in a water soluble container; mixing a pre-determined number of the water soluable containers containing the first component with water in a first mixing tank; mixing a pre-determined quantity of a first catalyst with the water and the first component in the first mixing tank; mixing a pre-determined quantity of a second catalyst with water in a second mixing tank; and combining the solutions within the first and second mixing tanks to cause a polymerization-cross linking reaction of the first component such that the first components solidify.
Claim 3
Dependent Claim
23 words
The method of claim 1 further including the step of: placing a pre-determined quantity of the second catalyst in a water soluble container.
Claim 4
Dependent Claim
18 words
The method of claim 1 where the first component comprises an acrylamide mixture of acrylamide and N, N-Methlynenebisacrylamide.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein the first catalyst comprises triethanolamine.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein the second catalyst comprises ammonium persulfate.
Claim 7
Dependent Claim
56 words
The method of claim 1 further comprising the step of pumping the aqueous solution of the first component, the first catalyst and water in the first mixing tank and the aqueous solution of the second catalyst and water in the second mixing tank into a mixing chamber to initiate the polymerization-cross-linking reaction of the first component.
Claim 8
Dependent Claim
44 words
The method of claim 1 further comprising the step of pressurizing the first mixing tank and the second mixing tank and conducting the solutions within the first and second mixing tanks into a mixing chamber to initiate the polymerization-cross-linking reation of the first component.
