METHOD FOR CONSTRUCTING GROUND IMPROVEMENT BODY
To provide a method for constructing a ground improvement body capable of developing a desired compressive strength while considering the environment.SOLUTION: The present invention comprises steps of drilling the ground while supplying bentonite liquid and filling an underground hole with drilling muddy water in which the bentonite liquid and excavated earth and sand are mixed, adding slag mixture mainly composed of blast furnace slag fine powder to drilling fluid that fills underground holes, and stirring and mixing the drilling fluid and the slag mixture in the presence of an alkaline stimulant.SELECTED DRAWING: Figure 1
【課題】環境に配慮しつつ所望の圧縮強度を発現させることの可能な、地盤改良体の構築方法を提供する。【解決手段】ベントナイト液を供給しながら地盤を削孔し、地中孔を前記ベントナイト液と掘削土砂が混じった掘削泥水で満たす工程と、前記地中孔を満たす掘削泥水に、高炉スラグ微粉末を主材とするスラグ混合液を添加する工程と、アルカリ刺激剤の存在下で、前記掘削泥水と前記スラグ混合液を攪拌混合する工程と、を備えることを特徴とする。【選択図】図１
