IMPACT DRILL USED IN PILE FOUNDATION WORK
To provide an impact drill used for excavating the ground with a pile foundation work.SOLUTION: An impact drill tows a slide hook 2, and lifts a rod 3 in a vertical upper direction, and thereby a rotary cylinder rotates according to movement of the rod 3 in the vertical upper direction, an impact part 5 rotates, a top surface of a mounting plate of the impact part 5 is exposed, sediment deposited in the bottom of the ground is picked up with the mounting plate, and the ground is made to be easily excavated. When towing of the slide hook 2 is stopped, the rod 3 falls in a vertical lower direction, thereby the rotary cylinder reversely rotates according to movement of the rod 3 in the vertical lower direction, the impact part 5 reversely rotates, the mounting plate of the impact part 5 coincides with a lower end face of a triangular plate 4, and impact to the ground of the impact drill increases when the impact drill is hammered to the ground.SELECTED DRAWING: Figure 1
【課題】杭基礎工事で地盤を掘削するために使用する衝撃ドリルを提供する。【解決手段】スライドフック２を牽引して、ロッド３を鉛直上方向に持ち上げることで、ロッド３が鉛直上方向に移動するのに合わせて回転筒が回転し、さらに衝撃部５が回転して、衝撃部５の取付板の天面が露出して、地盤の底に沈殿した土砂が取付板によって掬い上げられて、地盤を掘削しやすい状態にし、スライドフック２の牽引をやめると、ロッド３が鉛直下方向に落下することで、ロッド３が鉛直下方向に移動するのに合わせて回転筒が逆回転し、さらに衝撃部５が逆回転して、衝撃部５の取付板が三角板４の下端面と一致して、衝撃ドリルを地盤に打ち付けたときに衝撃ドリルの地盤への衝撃を増加させる。【選択図】図１
