To provide a pile head treatment method capable of securing required shot holes even where all of the shot holes are not arranged radially around a pile center in a pile head treatment of concrete piles installed at the site and achieving the same breaking effect as the case where the all of the shot holes are arranged radially around the pile center, as well as dramatically improving work efficiency.SOLUTION: This pile head treatment method includes: a step S02 of arranging a plurality of sheath pipes on pile reinforcement bars when assembling pile the reinforcement bars; a step S03 of filling concrete; a step S06 of loading charge material in a plurality of shot holes formed with the plurality of sheathe pipes; and a step S09 of horizontally breaking a pile head extra-fill part of the pile head using kinetic breaking material within the loaded charge material, wherein a part of the plurality of the charge material is formed as a first shot holes to configure a part of a radial arrangement around a pile center and the shot holes in the other part of the radially arrangement and at least a same number of shot holes are line-symmetrically formed regarding a direction of a specific pile diameter direction as a second shot hole.SELECTED DRAWING: Figure 3
【課題】場所打ちコンクリート杭の杭頭処理において全装薬孔を杭中心の放射状配置にしない場合でも所要の装薬孔を確保し、全装薬孔を杭中心の放射状配置にする場合と同様の破砕効果を得ることができ、しかも作業効率が大幅に向上する杭頭処理工法を提供する。【解決手段】この杭頭処理工法は、杭鉄筋の組み立て時に複数のさや管を杭鉄筋に配置する工程Ｓ０２と、コンクリートを打設する工程Ｓ０３と、複数のさや管により形成された複数の装薬孔に装薬材を装填する工程Ｓ０６と、装填された装薬材内の動的破砕剤により杭頭部の杭頭余盛部を水平破断する工程Ｓ０９と、を含み、複数の装薬孔の一部が杭中心の放射状配置の一部をなすように第１の装薬孔として形成され、放射状配置の残りをなす複数の装薬孔と少なくとも同数の装薬孔が第２の装薬孔として所定の杭直径方向に関して線対称に形成される。【選択図】図３
