Abstract
In a method of consolidating soils by injecting a hardner thereinto, a mixture of an aqueous solution of water glass and acidic reactant is employed as the hardener, the aqueous solution being prepared to be within the range of from weak acidity to weak alkalinity in pH value, to prevent the occurrence of pollution such as soil pollution or subterranean water polutions.

In a method of solidifying a soil or making soil water-tight by injecting a hardener thereinto, in which a mixture of water glass and acidic reacting agent is employed as said hardener, and said solution is blended so that the pH value thereof is within a range of from weak acidity of about fine to weak alkalinity of about 9, thereby to reduce the pollution of soil or subterranean water, characterized in that a liquid A which is a solution of one or two materials selected from the group consisting of a gel control agent and clay, and a liquid B which is a mixture of water glass and acidic reacting agent are employed as said hardener, and said liquids A and B are joined together and are injected into said soil, said liquid B being blended so that the pH thereof being maintained within a range of from acidity to weak alkalinity.
In a method of solidifying a soil or making soil watertight by injecting a hardener thereinto, in which a mixture of water glass and acidic reacting agent is employed as said hardener, and said solution is blended so that the pH value thereof is within a range of from weak acidity to weak alkalinity thereby to reduce the pollution of soil of subterranean water, characterized in that a liquid A which is a solution of acidic reacting agent, and a liquid B which is a solution of water glass are employed as said hardener, and said liquids A and B are joined together and are injected into said soil, each of said liquids A and B being blended so that the pH value of the liquid obtained by combining said liquids A and B is maintained within a range of from weak acidity of about five to weak alkalinity of about 9.
