MANUFACTURING SYSTEM OF SOIL IMPROVEMENT MATERIAL AND MANUFACTURING METHOD OF SOIL IMPROVEMENT MATERIAL
To correspond to errors such as concentration of solution to blend, and to prepare a soil improvement material at a time in large quantities by using an agitation tank.SOLUTION: A manufacturing system includes: a mixed liquid agitation tank 3 preparing mixed liquid by agitating A liquid containing colloidal silica and acid, and B liquid containing silicate; theory pH calculation means 42 calculating theory pH value of the mixed liquid based on the amount of the A liquid supplied to the mixed liquid agitation tank 3, the amount of the B liquid supplied to the mixed liquid agitation tank 3, and the pH value of the A liquid and the pH value of the B liquid; and addition amount calculation means 43 calculating an addition amount of the B liquid to add to the mixed liquid agitation tank 3 based on a difference between the actual pH value and the theory pH value of the mixed liquid.SELECTED DRAWING: Figure 1
【課題】混合する溶液の濃度等の誤差に対応すること、および、攪拌槽を用いて一度に大量に地盤改良材を作液することを可能にする。【解決手段】コロイダルシリカと酸とを含有するＡ液と珪酸塩を含有するＢ液とを攪拌して混合液を作液する混合液攪拌槽３と、混合液攪拌槽３に供給されたＡ液の量、混合液攪拌槽３に供給されたＢ液の量、Ａ液のｐＨ値およびＢ液のｐＨ値に基づいて、混合液の理論ｐＨ値を算出する理論ｐＨ算出手段４２と、混合液の実測ｐＨ値と理論ｐＨ値との差に基づいて、混合液攪拌槽３に追加するＢ液の追加量を算出する追加量算出手段４３とを備える。【選択図】図１
