GROUND EXPLORATION METHOD BY CONE PENETRATION TEST WITH WATER SAMPLING FUNCTION AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a subsurface exploration method, enabling quick water sampling at selective depths while ensuring cone penetration test data.;SOLUTION: The device of a remote control type having three component cones and water sampling function comprises a mechanism for avoiding the misjudgement of a water sampling depth and preventing contamination at the water sampling depth.;COPYRIGHT: (C)2001,JPO
