ORIGINAL POSITION TESTING DEVICE, METHOD FOR MEASURING GROUNDWATER LEVEL, AND METHOD FOR COLLECTING SOIL SAMPLE
PROBLEM TO BE SOLVED: To provide an original position testing device which can accurately measure a groundwater level and can surely collect a soil sample at a desired position with a simple constitution.SOLUTION: An original position testing device 4 for measuring a groundwater level and collecting a soil sample includes: an inner pipe 1 in which a water passage hole 11 is formed with a gap in a circumferential direction and an axial direction; and an intermediate pipe 2 which is arranged on the outer peripheral side of the inner pipe and has a plurality of side openings 21 provided at a position capable of overlapping the water passage hole. A tip port 24 is provided on the tip of the intermediate pipe, and a tip head part 13 projecting downward from the tip port is provided on the tip of the inner pipe so that the tip port is freely opened and closed.SELECTED DRAWING: Figure 1
【課題】精度よく地下水位を測定できるうえに、簡単な構成で確実に所望する位置の土試料を採取することが可能な原位置試験装置を提供する。【解決手段】地下水位の測定及び土試料の採取を行うための原位置試験装置４であり、周方向及び軸方向に間隔を置いて通水穴１１が穿孔された内管１と、内管の外周側に配置されて、通水穴に重ねることが可能となる位置に複数の側面開口２１が設けられた中管２とを備えている。さらに、中管の先端には先端口２４が設けられており、内管の先端には先端口の開閉が自在となるように先端口から下方に向けて突出させる先端ヘッド部１３が設けられている。【選択図】図１
