IMPREGNATING AGENT COMPOSITION FOR CONSOLIDATION OF ROCK BED OR GROUND, AND SOIL-STABILIZING AND ENHANCING WATER SEALING CONSTRUCTION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide an impregnating agent composition for consolidation of rock bed or ground that is formed of: an aqueous silicate solution mixture which does not need addition of a viscosity reduction agent and hydrophilic polyol modification on polyisocyanate, obtains stable workability and reactivity without being affected by a moisture particularly under such an environment that sump water and leakage water are much, is excellent in permeability, and has such a low possibility as to cause soil contamination; and a polyisocyanate composition.SOLUTION: An impregnating agent composition for consolidation of rock bed or ground contains: an aqueous silicate solution mixture which contains an aqueous silicate solution, an active hydrogen group-containing compound, a catalyst containing a tertiary amine catalyst and a compatibilizer containing an anion surface active agent; and a polyisocyanate composition.SELECTED DRAWING: None
【課題】 粘度低下剤の添加やポリイソシアネートへの親水性ポリオール変性を行うことなく、特に湧水・漏水が多い環境下においても水分に影響されることなく安定した作業性・反応性が得られ、また、浸透性に優れ、土壌汚染をひきおこす可能性の低い岩盤固結用の珪酸塩水溶液混合物と、ポリイソシアネート組成物からなる注入薬液組成物を提供すること。【解決手段】 珪酸塩水溶液、活性水素基含有化合物、３級アミン触媒を含む触媒、及び陰イオン系界面活性剤を含む相溶化剤を含有する珪酸塩水溶液混合物と、ポリイソシアネート組成物とを含むことを特徴とする、岩盤又は地盤固結用の注入薬液組成物により解決する。【選択図】 なし
