BOREHOLE BOTTOM GROUND PLATE LOADING TEST DEVICE
PROBLEM TO BE SOLVED: To accurately execute a hole inner plate loading test of the object ground, by efficiently removing slime of a hole bottom surface of a borehole.SOLUTION: A borehole bottom ground plate loading test device executes a plate loading test of a testing ground surface 2 by pressing the testing ground surface 2 by a loading plate 11 by making a loading surface 11b of the loading plate 11 reach up to the testing ground surface 2 of a borehole bottom by a hole drilling machine, by being stored in a borehole 4 in a state of holding the loading plate 11 on the lower end, and removes slime S deposited between the testing ground surface 2 and the loading surface 11b by a slime removing projection 20 formed on the loading surface 11b by rotating the loading plate 11. Thus, the plate loading test of the testing ground surface 2 can be accurately executed.SELECTED DRAWING: Figure 5
【課題】 ボーリング孔の孔底面のスライムを効率よく除去し、対象地盤の孔内平板載荷試験を精度良く行えるようにする。【解決手段】 載荷板11を下端に保持した状態で、ボーリング孔4内に収容され、削孔機によりボーリング孔底の試験地盤面2まで載荷板11の載荷面11bを到達させて試験地盤面2を載荷板11で押圧し、試験地面盤2の平板載荷試験を行うボーリング孔底地盤平板載荷試験装置であって、載荷板11を回転させて載荷面11bに形成されたスライム除去突起20で試験地盤面2と載荷面11bとの間に堆積するスライムSを除去する。これにより試験地盤面2の平板載荷試験を精度よく行うことができる。【選択図】 図5
