Patent ID: 8911181

Claim:
A method for soil stabilization comprising the steps of: providing a sodium silicate tank within a mobile trailer, said sodium silicate tank fluidly coupled to a hydraulic motor operated sodium silicate pump assembly for injecting a calculated amount of sodium silicate through said sodium silicate pump; providing a catalyst tank within said mobile trailer, said catalyst tank fluidly coupled to a catalyst chemical hydraulically operated variable proportioning mixing pump for injecting a calculated amount of catalyst; providing a water tank fluidly within said mobile trailer, said water tank coupled to said catalyst chemical pump for admixing a predetermined amount of water with said injected catalyst, said admixture directed to a hydraulic motor operated water/catalyst pump; controlling each said hydraulic motor by a manual operated hydraulic control valve; monitoring sodium silicate pump discharge pressure and flow rate and adjusting said sodium silicate pump to meet a predetermined pressure and flow rate; monitoring water/catalyst pump discharge pressure and flow rate and adjusting said water/catalyst pump to meet a predetermined pressure and flow rate; coupling discharge lines from said water/catalyst and said sodium silicate to a static mixer as a function of a discharge volume rate; distributing the mixed admixture passed from said static through a flexible hose to a soil site, maintaining a predetermined discharge pressure through said flexible hose by varying flow of hydraulic fluid to said hydraulic motors; bleeding an amount of the mixed admixture through a bleed line and monitoring the time the mixed admixture requires to cure into a solid and adjusting said pumps accordingly; and terminating pumping when a predetermined discharge pressure is reached based upon a calculated curing time obtained from said bleeding step.
