METHOD AND APPARATUS FOR A CONE PENETRATION TEST WITH WHIPSTOCK-ENABLED SOIL SAMPLING

摘要

A method and apparatus for geotechnical soil sampling in conjunction with theConePenetration Test (CPT) is provided. The apparatus involves a tubular whipstockcell affixedbetween push rods and the lower elements of a cone penetrometer. The whipstockcellincludes a whipstock having a beveled face. The whipstock face is orientedtowards asampling window pre--formed in the whipstock cell. The apparatus also includesat least onepush rod connected to the proximal end of the whipstock cell, and an elongatedsampling roddimensioned to be slidably moved through the at least one push rod en route tothe whipstockcell. The apparatus additionally comprises a soil sampler residing at a distalend of the pushrod. A method of taking soil samples is also provided herein.
