While the sample and push lengths are shorter than the tube, see 7. Unconfined compression tests should be only used with caution or based on experience because they often provide unreliable measure of undrained strength, especially in fissured clays. Low-plasticity silts can be sampled but in some cases asgm the water table they may not be held in the tube and a piston sampler may be required to recover these soils. Figure 2 shows ast standard sampler with a ball check valve in the head, which is used in fluid rotary drilled holes.
