PENETRATION PILE AND METHOD FOR PENETRATING PENETRATION PILE
PROBLEM TO BE SOLVED: To provide a penetration pile which can be penetrated into the ground with rotational force not being applied to although the penetration pile has a spiral part; and a method for penetrating the penetration pile.SOLUTION: A pile used as a foundation of a structure comprises a rod-like pile main body part 2 having a tapered pile tip part 2a whose diameter is gradually contracted toward the penetration direction, and a spiral part 3 having a spiral surface 3a which is formed in a spiral manner at least along the outer peripheral surface of a part or the whole of the pile tip part 2a in the outer peripheral surface of the pile main body part 2 and which converts a reaction force into a rotational force of the pile main body part 2 in receiving the reaction force from the ground when the pile main body part 2 is penetrated into the ground. When the pile head 4 of the pile is struck or pressed in the penetration direction, the pile is penetrated into the ground while rotating autonomously.SELECTED DRAWING: Figure 1
【課題】螺旋状の部分を備えた杭でありながら、杭に回転力を加えることなく地盤に貫入することのできる貫入杭および貫入杭の貫入方法を提供する。【解決手段】構造物の基礎として用いられる杭は、貫入方向に向けて漸次縮径する先細りの杭先端部２ａを有する棒状の杭本体部２と、前記杭本体部２の外周面のうち少なくとも前記杭先端部２ａの一部または全部の外周面に沿って螺旋状に形成され、前記杭本体部２が地盤に貫入する際の前記地盤からの反力を受けると前記反力を前記杭本体部２の回転力に変換する螺旋面３ａを有する螺旋部３と、を備え、前記杭の杭頭４を貫入方向へ打撃または押圧すると自律的に回転しながら地盤に貫入する。【選択図】図１
