CHEMICAL SOLUTION COMPOSITION FOR INJECTION INTO GROUND
To provide an urethane-based chemical solution composition for injection into ground that has excellent reaction activity and causes less environmental pollution, and provide an urethane-based chemical solution for natural ground consolidation that can form a high-strength consolidation body, and does not cause problems of white turbidness in contact with water such as leaked water and a spring, foaming and the like.SOLUTION: A chemical solution composition for injection into ground contains: A liquid containing a silicate aqueous solution, an active hydrogen group-containing compound and a catalyst as essential components; and B liquid containing polyisocyanate as an essential component. As the polyisocyanate, an aliphatic polyisocyanate prepolymer is contained in the B liquid, and as the active hydrogen group-containing compound, at least primary and/or secondary amino group-containing compound is contained in the A liquid.SELECTED DRAWING: None
【課題】反応活性に優れ、環境汚染の少ないウレタン系の地盤注入用薬液組成物を提供することにあり、また他の課題とするところは、高強度の固結体を形成し得る、漏水や湧水等の水に接触した際の白濁化や泡立ちの如き問題を惹起することのない、ウレタン系地山固結用薬液を提供する。【解決手段】ケイ酸塩水溶液と活性水素基含有化合物と触媒とを必須の成分として含むＡ液と、ポリイソシアネートを必須の成分として含むＢ液とからなる地盤注入用薬液組成物において、前記ポリイソシアネートとして、脂肪族ポリイソシアネートプレポリマーが前記Ｂ液に含有せしめられると共に、前記活性水素基含有化合物として、少なくとも１級及び／又は２級アミノ基含有化合物を前記Ａ液に含有せしめるようにした。【選択図】なし
