METHOD FOR CONSTRUCTING SMALL-DIAMETER CAST-IN-PLACE PILE
To provide a method for constructing a small-diameter cast-in-place pile capable of improving workability while reducing a weight of a core material.SOLUTION: A reinforcing core material 30 in which a plurality of depressions 32 are formed along a pipe axial direction and a pipe circumferential direction on an outer peripheral surface of a pipe main body 31 is used. After the reinforcing core material 30 is inserted into a pile hole 20, a consolidating material 25 is injected into the pile hole 20 and inside the reinforcing core material 30 through the reinforcing core material 30 to construct a small-diameter cast-in-place pile 10.SELECTED DRAWING: Figure 1
【課題】芯材の軽量化を図りつつ、施工性を改善できる、小口径場所打ち杭の構築方法を提供すること。【解決手段】管本体３１の外周面に管軸方向および管周方向に沿って複数の窪み部３２を形成した補強芯材３０を使用し、杭孔２０内に補強芯材３０を挿入した後に補強芯材３０を通じて杭孔２０内および補強芯材３０の内部に固結材２５を注入して小口径場所打ち杭１０を構築する。【選択図】図１
