Apparatus for Extraction of Undisturbed Samples on Noncohesive Subsoils1
- W. M. Schuh2
A sampler was designed and tested for extracting 60- by 53-mm (length by depth) undisturbed core samples from subsoils. The sampler consists of a sample cylinder “barrel,” and an “adaptor block” for fitting the barrel to the end of a 76.1-mm o.d. hydraulic probe tube. Samples are taken by augering to the desired depth, and using the tube and sampler assembly to extract the sample. The tube and sampler assembly can also be used with a protective steel anvil to remove samples in shallow subsoils without a hydraulic probe. Samples on sands have been taken as deep as 2.5 m using the hydraulic probe, and as deep as 0.61 m using the anvil and maul method.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
