FOUNDATION INJECTION MATERIAL AND FOUNDATION INJECTION METHOD
To provide a foundation injection material for forming a foundation excellent in long-term durability such as foundation reinforcement, foundation water tightness, tight-seal of a waste, construction of cut-off performance, liquefaction measure and so on, by preventing strength deterioration of a sand gel due to foundation injection, and by imparting sufficient water tightness and strength and by maintaining not only persistence of solidification but also strength.SOLUTION: In a foundation injection material for forming a foundation into an improved foundation having durability by injecting an injection material formulation liquid containing clay in soft or a leakage foundation, the foundation injection formulation liquid contains a silica solution, bentonite and an acidic reaction agent, the formulation liquid has the pH of 3 to 4.5, a gelling time is 10 minutes to 300 minute, a silica concentration is 1 to 10 wt.%, and a bentonite concentration is 1 to 5 wt.%.SELECTED DRAWING: None
【課題】地盤注入によるサンドゲルの強度低下を防ぎ、十分な水密性と強度を付与するとともに、単に固結の持続性のみならず、強度を維持して地盤強化、地盤水密化、廃棄物の密封化、止水性の構築、液状化対策工等、長期耐久性に優れた地盤を形成する地盤注入材を提供する。【解決手段】軟弱あるいは漏水地盤に粘土を含む注入材配合液を注入して該地盤を耐久性のある改良地盤を形成する地盤注入材において、該地盤注入材配合液はシリカ溶液とベントナイトと酸性反応剤を有効成分として含み、該配合液はｐＨが３〜４．５を呈し、ゲル化時間が１０分〜３００分、シリカ濃度が１〜１０ｗｔ％、ベントナイト濃度が１〜５ｗｔ％である地盤注入材。【選択図】なし
