ABSTRACT:
An assembly for extracting discrete soil samples from subsurface soil at a lurality of selected depths includes an elongated outer tubular housing, and a soil sample tube for disposal in the outer tubular housing. The soil sample tube is movable axially in the outer tubular housing and provided with a feature thereon for locking the soil sample tube in the outer tubular housing in a fully inserted position in the outer tubular housing. The replaceable soil sample tube defines a sample chamber proximate a distal end thereof. The assembly further includes a cone tip assembly including a cone tip member and a cone tip rod, the cone tip member being fixed to a distal end of the cone tip rod. The cone tip rod is movable axially in the soil sample tube, the cone tip member having a locking feature thereon for locking the cone tip member at the distal end of the soil sample tube with a cone portion of the cone tip member extending distally beyond a distal end of the outer tubular housing. A method for extracting soil samples, utilizing the above assembly, is also contemplated.
