Abstract
PURPOSE: To seek the stabilization and cut-off of ground over a long period by injecting into the ground an isocyanate group-terminated hydrophilic urethane prepolymer and a specific hardening agent which mixing then each other.
CONSTITUTION: The objective stabilization can be accomplished by injecting into the ground by means of the 1.5-shot process a grout comprising (A) 5W95wt% of a major agent consisting of an isocyanate group-terminated urethane prepolymer or a product obtained by incorporating it with an inert diluent and (B) 95W5wt% of a hardening agent consisting of a dilute (0.1W5wt%) aqueous solution of an alkali (alkaline earth) metal silicate. Said propolymer can be prepared by reaction between an organic polyisocyanate and a hydrophilic polyoxyalkylene polyol having an average molecular weight of 400W20,000 in an equiralent ratio NCO/OH of 2W8. The polyoxyalleylene polyol mentioned above can be synthesized by addition polymerization of an alkylene oxide to an active hydrogen compound, containing 20W 80wt%, based on the total amount of the alkylene oxide, of ethylene oxide in the alkylene oxide chain.
