Abstract
PURPOSE: To solidify firmly the ground without polluting underground water, i.e. without making underground water alkaline, by jetting water glass into an aq. soln. of an acidic reactant, mixing the resulting aq. soln. of non-alkaline silicic acid with a cement suspension, and injecting the mixture into the ground.
CONSTITUTION: An acidic reactant 1' such as sulfuric acid and water 1" are introduced through pipes 6', 6" into a mixing vessed 2 to prepare an aq. soln. of the acidic reactant. Then water glass 1 is passed through a pipe 6, jetted through jetting holes 8 of a jetting device 7 into the vessel 2, and mixed with the aq. soln. of the acidic reactant by rotating an agitating blade 9. During the mixing, a pH change is detected by a detector 4, and transmitted to a controller 5. When the pH reaches a required value between an acidic pH and neutral pH, the supply of water glass is suspended to form an aq. soln. of non-alkaline silicic acid. This aq. soln. of non-alkaline silicic acid is mixed with a cement suspension in a mixer, etc. The mixture is injected into soft ground or the ground where water leaks out.
EFFECT: The compsn. is excellent in penetration into the ground.
