DRILLING BIT AND STEEL PIPE PILE
To improve mounting accuracy without complicating construction work when individually mounting a drilling bit to the tip of a steel pipe pile.SOLUTION: A drill bit that comprises a plate-like main body portion that is joined to an axial end face of a steel pipe pile and includes a portion that protrudes from an end face toward an inner peripheral surface side or an outer peripheral surface side of the steel pipe pile when viewed in the axial direction, and an extension portion formed continuously from a portion of the main body portion protruding toward the inner peripheral surface side or the outer peripheral surface side of the steel pipe pile, extending along the inner peripheral surface or the outer peripheral surface, and directly or indirectly joined to the inner peripheral surface or the outer peripheral surface is provided.SELECTED DRAWING: Figure 1
【課題】鋼管杭の先端に掘削ビットを個別に取り付けるにあたり、施工を煩雑化することなく取り付け精度を向上させる。【解決手段】鋼管杭の軸方向の端面に接合され、上記軸方向に見た場合に上記端面から上記鋼管杭の内周面側または外周面側に突出した部分を含む板状の本体部と、上記本体部の上記鋼管杭の内周面側または外周面側に突出した部分に連続して形成され、上記内周面または上記外周面に沿って延び、上記内周面または上記外周面に直接的または間接的に接合される延長部とを備える掘削ビットが提供される。【選択図】図１
