WATER BOTTOM GROUND PENETRATION DEPTH MEASUREMENT DEVICE
PROBLEM TO BE SOLVED: To provide a measurement device capable of accurately measuring a penetration depth of a penetration probe into a water bottom ground.SOLUTION: On a water bottom ground penetration depth measurement device 20, a cross frame 27 is fixed on an upper end side in a longer direction of a penetration probe 21 to be inserted to the water bottom ground and an underwater video camera 29 is fit to each arm part. A water bottom detection member 30 that can relatively move is fixed near a cone on a tip side of the penetration probe 21. A ring-shaped plate 31, which is fastened to a surface of the water bottom ground when the penetration probe 21 is penetrated, is formed at a lower part of the water bottom detection member 30. A luminescent LED is fit as a gage mark 33 on a top face of the plate 31 at angular interval of 90 degrees. A three-dimensional position information depending on change in a distance between the underwater video camera 29 and the gauge mark 33 is obtained by photographing the gauge mark 33 with the underwater video camera 29 when the penetration probe 21 is penetrated in the ground. A penetration depth into the water bottom ground by the penetration probe 21 is calculated by a measurement means based on the three-dimensional position information.SELECTED DRAWING: Figure 1
【課題】貫入プローブによって精度良く水底地盤内への貫入深度を測定できる計測装置を提供する。【解決手段】水底地盤貫入深度計測装置２０は、水底地盤へ貫入する貫入プローブ２１の長手方向の上端側に十字フレーム２７を固定し、各アーム部に水中ビデオカメラ２９を取り付けた。貫入プローブ２１の先端側のコーン近傍には相対移動可能な水底検知部材３０を固定した。水底検知部材３０の下部には貫入プローブ２１の貫入時に水底地盤の表面に留まるリング状のプレート３１を設けた。プレート３１の上面に９０度間隔で標点３３として発光用ＬＥＤを設けた。貫入プローブ２１の地盤への貫入時に水中ビデオカメラ２９で標点３３を撮影することで、水中ビデオカメラ２９と標点３３との距離の変化に応じた三次元位置情報を取得する。三次元位置情報に基づいて計測手段によって貫入プローブ２１の水底地盤への貫入深度を演算する。【選択図】図１
