SOLIDIFIED PILE FORMING METHOD
To provide a solidified pile forming method that performs prejetting which uses a novel excavation fluid that is a compound of a relatively small amount of active ingredients and effectively excavates hard clay layers, and that improves mud discharge.SOLUTION: The solidified pile forming method is for forming a solidified pile by jetting a solidification material from a solidification material jet nozzle. Before the solidification material is jetted from the solidification material jet nozzle, prejetting is performed to soften the ground in advance using an excavation fluid that includes an anionic dispersant.SELECTED DRAWING: Figure 1
【課題】有効成分の比較的少ない配合で、硬質粘土層を効果的に切削し、排泥を高める新たな切削液を使用するプレジェットを行う固化処理杭造成工法を提供すること。【解決手段】固化材噴射ノズルから固化材を噴射させて固化処理杭を造成する固化処理杭造成工法において、固化材噴射ノズルから固化材を噴射させる前に、陰イオン性分散剤を含有する切削液で予め地盤を緩めるプレジェットを行う。【選択図】図１
