HIGH STRENGTH ROTARY PENETRATION PILE
PROBLEM TO BE SOLVED: To solve the problem by which there is a case of being unable to sufficiently secure bearing force depending on a ground state, though being largely used in construction and civil engineering work, since a rotary penetration pile can construct a foundation pile without earth removal.SOLUTION: A high strength rotary penetration pile is constituted by fixing a cylindrical steel skirt material to the outer edge of a rotary propulsion blade fixed to the vicinity of a tip part of a steel pipe pile body.
【課題】 回転貫入杭は無排土で基礎杭を構築出来るので、建築土木工事で大いに利用されているが、地盤の状況などによっては耐力を十分に確保出来ない場合があった。【解決手段】鋼管製の杭本体の先端部近傍に固着せしめられている回転推進翼の外縁に、円筒状をなした鋼製のスカート材を固着せしめて高耐力回転貫入杭を構成した。【選択図】 図１
