GEOLOGICAL SURVEY DEVICE AND METHOD
To provide a geological survey device and a method which can easily investigate geology even when a borehole is an oblique hole.SOLUTION: A geological survey device comprises: a hollow stick-shaped rod 11b that can be moved in and out of a borehole 1 and allows water to flow inside; a probe 12 that is provided on the tip end side of the rod 11b and provided with an image pickup device 12a for photographing an inner wall surface 1a of the borehole 1; and a cylindrical water discharge part 14 provided on the outer circumference of the probe 12 while being connected to the tip of the rod 11b so that an annular gap G into which water passed through the inside of the rod 11b can flow is formed between itself and the probe 12. The opening part at the tip of the water discharge part 14 is located closer to the rear end side of the rod 11b than the image pickup device 12a, so that water that has passed through the gap G can be ejected from the opening part toward the photographing range of the image pickup device 12a.SELECTED DRAWING: Figure 1
【課題】ボーリング孔が斜孔である場合にも簡便に地質を調査することを可能とする地質調査装置及び方法を提供する。【解決手段】ボーリング孔１に対して出し入れ可能であり、内部を水が流通可能とする中空棒状のロッド１１ｂと、ロッド１１ｂの先端側に設けられ、ボーリング孔１の内壁面１ａを撮影する撮像装置１２ａを備えるプローブ１２と、ロッド１１ｂの内部を通過した水が流入可能な円環状の空隙Ｇがプローブ１２との間に形成されるようにして、ロッド１１ｂの先端に接続しつつ、プローブ１２の外周に設けられる、円筒形状の水出し部１４とを備え、水出し部１４は、その先端の開口部分が、撮像装置１２ａよりもロッド１１ｂの後端側に位置しており、空隙Ｇを通過した水が当該開口部分から撮像装置１２ａの撮影範囲に向けて噴射されることを可能とする。【選択図】図１
