Abstract

PURPOSE: To improve soil effectively by a method wherein an non-alkaline aqueous silicic acid solution obtained by adding waterglass into an acidic solution and a suspending substance containing metal oxide, slag, cement or the like as an effective component are injected into weak or leaking ground to be solidified.
CONSTITUTION: Waterglass is added into an acidic solution such as sulfuric acid to obtain a non-alkaline aqueous silicic acid solution with pH value of below 5 and the value of this solution shown by formula (where [H+] is mole concn. of hydrogen ion, [SiO2] is mole concn. of silicon dioxide, n is mole ratio of waterglass) is adjusted to below 1×10-3 pref. Separately, a suspending substance containing one or more of a component selected from metal oxide, slag, fly ash, cement, clay, gypsum and lime as an effective component is prepared and this substance is used along with said non-alkaline aqueous silicic acid solution and the obstained solution is injected into weak or leaking ground to be solidified. Thereby, the solidified strength is increased and the water quality maintainance of subterranean water in an applied area is enhanced.
