PILE HEAD TREATMENT BUCKET HEIGHT POSITION INDICATOR
To provide a structure capable of quickly and accurately matching a pile head treatment bucket to a pile head treatment target height.SOLUTION: A pile head treatment bucket height position indicator 31 includes a vertical member 32c projecting upward from the pile head treatment bucket 10, a lateral member 32b which extends laterally from an upper end side portion of the vertical member and projects to an outer diameter side from the pile head treatment bucket and is raised from an upper edge of the pile head treatment bucket by a first predetermined dimension (Ha - burr dimension in vertical direction), and a connecting portion 33 connecting a lower end portion of the vertical member and the pile head treatment bucket. The lateral member is brought to the same height position as an upper end of an anchor reinforcing bar 103 projecting upward from a designed top end height T of a cast concrete pile, so that the pile head treatment bucket height position indicator indicates that a height position of a lower edge of the pile head treatment bucket is a height position Y lower than the upper end of the anchor reinforcing bar by a second predetermined dimension (Ha + Hb + Hc).SELECTED DRAWING: Figure 8
【課題】杭頭処理バケットを杭頭処理目標高に迅速かつ正確に合わせることができる構造を提供する。【解決手段】杭頭処理バケット高さ位置表示器３１は、杭頭処理バケット１０から上方へ突出する上下方向部材３２ｃと、上下方向部材の上端側部分から横方向に延出して杭頭処理バケットよりも外径側へ突出し杭頭処理バケットの上縁から第１所定寸法（Ｈａ−カエリ上下方向寸法）だけ高くされる横方向部材３２ｂと、上下方向部材の下端側部分と杭頭処理バケットを連結する連結部３３とを備え、横方向部材が場所打ちコンクリート杭の設計天端高Ｔから上方へ突出するアンカー筋１０３の上端と同じ高さ位置にされることにより、杭頭処理バケットの下縁の高さ位置がアンカー筋の上端から第２所定寸法（Ｈａ＋Ｈｂ＋Ｈｃ）だけ下がった高さ位置Ｙであることを表示する。【選択図】図８
