ORIGINAL POSITION TESTING DEVICE, GROUND WATER LEVEL MEASUREMENT METHOD, AND SOIL SAMPLING METHOD
PROBLEM TO BE SOLVED: To provide an original position testing device of a simple structure capable of accurately measuring an underground water level and sampling soil at a desired position for certain.SOLUTION: An original position testing device 4 is for measuring an underground water level W and sampling soil, and includes: an inner tube 1 having water passage holes 11, ... pierced in a circumferential direction and an axial direction leaving an interval; an intermediate tube 2 disposed on an outer peripheral side of the inner tube and provided with a plurality of side surface openings 21, ... at a position that may be overlapped with the water passage hole; and a cover part 22 and a tip head part 12 provided at a tip of the inner tube and the intermediate tube for freely opening/closing a tip port 24.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Ｗ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である。そして、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、内管及び中管の先端に設けられて先端口２４の開閉を自在にする蓋部２２及び先端ヘッド部１２とを備えている。【選択図】図１
