A device for procuring undisturbed cores of cracking-clay soils

Abstract

A device is described which inserts a 10.9 cm diameter soil core into a rigid liner during sampling. The technique is quick and simple and has been used to obtain cores to 60 cm depth in a cracking-clay soil. The sampling tool could be constructed of any dimensions and appears suitable for a range of soil types. Evidence presented indicates that the cores suffer a minimum of compaction.
