GROUND REINFORCEMENT METHOD, AND GROUND SOLIDIFICATION MATERIAL USED IN THE SAME
To provide a ground reinforcement method which achieves long-term stability of a ground having a slope that possibly becomes unstable for a long term and collapses while being stable at present time, by using a ground solidification material by microorganism metabolite in the ground.SOLUTION: A ground solidification material forming calcium carbonate by microorganism metabolite is sprayed to, injected into, mixed with, or high-pressure jet and injected into a ground having a slope 1 that possibly collapses, and thereby the calcium carbonate is precipitated and a solidification region 5 by the calcium carbonate is formed. When one or a plurality of kinds of the ground solidification material or a component constituting the ground solidification material are mixed with any one of clay, pozzolan, porous silica, and white carbon, or a plurality of kinds of fine particles, and the mixture is injected into the ground, the calcium carbonate can be gradually precipitated into the ground. A ground solidification material is penetrated in the ground where the fine particles have been previously penetrated, and the calcium carbonate can be precipitated.SELECTED DRAWING: Figure 1
【課題】現時点では安定している地盤であるものの、長期的に不安定化して崩壊に到る可能性がある斜面などを有する地盤に、微生物代謝による地盤固結材を用いて、地盤の長期的な安定を図る地盤強化方法を提供する。【解決手段】地盤崩落の可能性のある斜面１等を有する地盤等に、微生物代謝によって炭酸カルシウムを形成する地盤固結材を散布、注入、混合、あるいは高圧噴射注入することによって、炭酸カルシウムを析出させ、炭酸カルシウムによる固結領域５を形成させる。地盤固結材又は地盤固結材を構成する組成分の１種又は複数種を、粘土、ポゾラン、多孔質シリカ、ホワイトカーボンのいずれか、または複数種の微粒子と混合して地盤中に注入すれば、徐々に炭酸カルシウムを地盤中に析出させるようにすることができる。あるいは、予め前記微粒子を浸透させた地盤に地盤固結材を浸透せしめて、炭酸カルシウムを析出させることもできる。【選択図】図１
