EARTH ANCHOR AND FIXATION METHOD OF EARTH ANCHOR
PROBLEM TO BE SOLVED: To provide an earth anchor that has superior long-period durability and can be simply and tightly fix the ground, and a fixation method of the earth anchor.SOLUTION: The present invention relates to an earth anchor 1 comprising: a tension rod 21 having a male screw 21 formed on an outer peripheral surface; a plurality of fixation members 3 fitted rotatably to a tip side of the tension rod 2; a stopper part 4 restricting the fixation member 3 from spreading at a predetermined angle or larger; a wedge pipe 5 which is hollowed to have a through hole 51 having a larger diameter than the tension rod 2, and is movable along the axis of the tension rod with the tension rod inserted into the through hole 51; and a screw pipe 6 which has, on its inner peripheral surface, a female screw capable of threadably engaging the male screw 21 of the tension rod, and moves to an axial tip side of the tension rod 2 by being screwed to the tension rod 2 and also press the wedge pipe 5 against the plurality of fixation members 3 from a rear end side of the wedge pipe 5 to cause the plurality of fixation members 3 to expand.SELECTED DRAWING: Figure 1
【課題】 長期耐久性に優れており、簡易且つ強固に地盤に定着させることができるアースアンカー及びアースアンカーの定着方法を提供する。【解決手段】 外周面に雄ねじ２１が形成されている引張りロッド２１と、引張りロッド２の先端側に回動可能に取り付けられ複数の定着部材３と、定着部材３が所定角度以上は拡翼しないように規制するストッパ部４と、引張りロッド２の径よりも大径の貫通孔５１を有するように中空状に形成され、引張りロッドを貫通孔５１内に挿通させた状態で引張りロッドの軸方向に移動可能な楔管５と、内周面に引張りロッドの雄ねじ２１と螺合可能な雌ねじを有し、引張りロッド２に対してねじ込まれることにより引張りロッド２の軸方向の先端側へ移動して、楔管５の後端側から楔管５を複数の定着部材３に対して押し込むことで、複数の定着部材３を拡翼させるねじ管６とを備えるアースアンカー１。【選択図】図１
