GROUTING LIQUID COMPOSITION FOR STABILIZING SOIL, ETC., AND STABILIZATION AND REINFORCEMENT OF SOIL USING THE SAME

摘要

PURPOSE:To provide a grouting liquid composition useful for the consolidation and stabilization of an unstable part of a rock-bed, ground, artificial construction, etc., and to provide a stabilization, reinforcement and water-stopping process using the grouting composition. CONSTITUTION:The objective grouting liquid composition is composed of (A) an aqueous solution of sodium silicate and (B) a hydrophilic urethane prepolymer containing oxyethylene chain. A ground or an artificial construction can be stabilized and reinforced by injecting and solidifying the grouting composition. Since the hydrophilic urethane prepolymer (B) has high compatibility with the aqueous solution of sodium silicate (A) and high affinity to rock-bed, ground and artificial construction, the composition has improved penetration property into the rock-bed, etc., the strength of the consolidated composite is increased and the safety of the application work is improved.
