Soil Core Sampler: Single and Bi-partite

Hand-operated equipment can be applied for soil research up to a depth of 5 to 10 meter. The mutual quality of many gouge augers is that they all are fitted with an almost half-cylindrical operational part with parallel cutting edges running vertically, justifying the name gouge auger. This operational part may vary in length as well as in diameter. The most suitable length depends on the penetration resistance, the substance of the soil and the required boring depth. The longer the operational part the more vulnerable the auger is to torsion. The selection of the most suitable diameter depends on the composition and the structure of the soil and on the purpose of the research.
