sampler is commonly used to obtain relatively undisturbed samples of cohesive.

The rugged stainless steel construction cuts. Split Barrel Sampler: (a) Open sampler with soil sample and cutting shoe. Soil Core Samplers allow the user to collect relatively undisturbed samples from the subsurface or pre-augered boreholes. The GP sampler can obtain high quality sandy and gravelly soils with fines which was inapplicable to be obtained by freezing sampling method famous for high quality. Geotech hand auger kits are ideal for collecting disturbed or undisturbed soil samples near the surface. 1-1/2' X 12' Stainless Steel Soil Core Sampler Cup & Cap, 5/8' Thread. Polymer Gel reduces friction during sampling process and soil extrusion and it work to maintain sample in high quality. Undisturbed samples are generally taken by cutting blocks of soil or rock, or by pushing or driving tubes into the ground. Undisturbed soil means soil or soil profile unaltered by filling, removal, or other manmade changes with the exception of agricultural activities. The relationship of piston thrust pressure and displacement of piston during sample extrusion is shown in Figure-1. The effect of reducing the friction was confirmed during extrusion of the soil sample as well. The polymer solution is coated on a surface of a soil sample, and reduces friction between the sample tube and the sample during the sampling process.

used to collect relatively undisturbed soil samples for geotechnical analyses, such as. One of the major features of this sampling method is that polymer solution of high concentration is used as its drilling fluid for lubricant and not circulated unlike conventional drilling fluid. Soil Samples for Volatile Organic Compounds (VOC) Analysis. 2.2) to obtain standard undisturbed samples. Gel-Push (GP) sampler was developed by Kiso-Jiban Consultants in cooperation with Professor Tani, of Graduated School of Engineering, Yokohama National University, to obtain high quality undisturbed soil samples. Undisturbed samples may be obtained by handcutting blocks of soil in shallow pits, but it is more common to use sample tubes (described in Section B.
