| description | To provide a ground improvement method capable of improving compression strength of soil cement even when using acid soil containing an organic material such as humic acid, fulvic acid, humin, and bitumen.SOLUTION: A ground improvement method includes the following steps 1 to 3. In the step 1, a slurry is prepared by mixing water, hydraulic powder, and (A) colloidal silica with 0 mV or more and +50 mV or less of surface electric potential (hereinafter referred to as (A) component). In the step 2, the slurry obtained in the step 1 is injected into a ground and a mixture is obtained by mixing the slurry with soil. In the step 3, the mixture of the slurry and soil obtained in the step 2 is solidified.SELECTED DRAWING: None
【課題】フミン酸、フルボ酸、ヒューミン、ビチューメンなどの有機物を含む酸性土の土壌を用いた場合でもソイルセメントの圧縮強度を高めることができる、地盤の改良工法を提供する。【解決手段】下記の工程１～３を有する地盤の改良工法。＜工程１＞水と、水硬性粉体と、（Ａ）表面電位０ｍＶ以上＋５０ｍＶ以下であるコロイダルシリカ（以下、（Ａ）成分という）とを混合してスラリーを調製する工程。＜工程２＞工程１で得られたスラリーを地盤に注入して、スラリーと土壌とを混合して混合物を得る工程。＜工程３＞工程２で得られたスラリーと土壌の混合物を固化させる工程。【選択図】なし |
