In-situ frozen sampling
Enables high-precision ground response analysis! Introducing high-quality sand and gravel sampling techniques.
"Original Position Freezing Sampling" is a technique for collecting undisturbed samples from sandy and gravelly soil layers. Sampling is conducted in a frozen state through core drilling from the frozen ground. Furthermore, by handling the samples in a frozen state from the time of sampling until just before the soil tests, we can provide high-quality samples with minimal disturbance effects. This technique is applicable to non-cohesive soils such as sandy soils, gravelly soils, and rock materials. [Ground Conditions and Sampling Conditions] ■ Ground with high saturation necessary for freezing ■ Ground with low fine particle content ■ Ground that can achieve moderate confining pressure ■ Freezing occurs in a state where pore water can escape outward from the freezing pipe ■ Sampling is conducted from areas away from the freezing pipe *For more details, please refer to the PDF document or feel free to contact us.
