Soil sample rings

Soil samples of specific volume are taken with penetration cylinders while largely preserving the soil structure. The puncture cylinder is driven into the soil and the soil sample is separated from the surrounding soil. Subsequently, the closed puncture cylinder is transported as gently as possible. The volume of the driven-in ring leads to compaction of the soil in the edge area. The smaller the wall thickness of the piercing cylinder and the larger the volume of the soil sample, the smaller the influence of compaction. The rings are usually driven into the soil with a hammer. The resulting vibrations can lead to changes in the sample structure. In very dry, hard soils, it is not possible to take penetration cylinder samples because the penetration cylinder cannot be driven in.

Physical and chemical parameters can be determined on the puncture cylinder samples. In addition, soil parameters such as pore volume or hydraulic conductivity can be determined in laboratory tests.

We offer puncture cylinders made of stainless steel and acrylic in different sizes. The cylinders are also suitable for some of our devices, e.g. for the "mobile device for the sampling of undisturbed soil columns" or the "laboratory device for the sampling of undisturbed soil columns" or for our ku-pf apparatus. Appropriate accessories facilitate the usually physically heavy work of sampling and improve the quality of the samples.
