CUTOFF WALL CONSTRUCTION METHOD
To provide a cutoff wall construction method capable of using a compact single axis boring machine with excellent workability even in narrow situations such as in an urban area.SOLUTION: A cutoff wall A construction method comprises; a step to erect in a preceding pile bore 16 a core member 18 with a guide function preventing its deviation; a step to form a following pile hole 17 placed over between both of adjacent previous piles 25, 25 by rotating a bit 3 with a ring between the core members 18, 18 with a guide function preventing its deviation after forming the previous piles 25 in intervals through filling low strength solidification material 24 in the preceding pile bores 16; and a step to form a following pile 27 through filling solidification material 26 in the following pile bore 17, which can cut off water between both of the following piles 25, 25.SELECTED DRAWING: Figure 4
【課題】小型の単軸ボーリング機を用いることができ、都市部等の狭隘部においても施工性に優れた遮水壁の構築方法の提供。【解決手段】遮水壁Ａの構築方法は、先行杭孔１６に逸脱防止ガイド兼用芯材１８を建て込み、先行杭孔１６に低強度固化材２４を充填して間隔を置いて先行杭２５を形成した後、両逸脱防止ガイド兼用芯材１８，１８間でリング付きビット３を回転させ、隣り合う両先行杭２５，２５間に跨る後行杭孔１７を形成し、後行杭孔１７に固化材２６を充填して後行杭２７を形成し、両先行杭２５，２５間を遮水することができる。【選択図】図４
