Description

Soil sampling device

Technical Field

The invention relates to the technical field of soil sample collection, in particular to a soil sampling device.

Background

Sampling refers to the process of extracting an individual or sample from a population, i.e., the process of testing or observing the population. Random sampling and non-random sampling. The former refers to a sampling method for extracting samples from the population according to the randomization principle, which does not have any subjectivity, and includes simple random sampling, systematic sampling, whole group sampling, and hierarchical sampling. The latter is a method of sampling samples from the opinion, experience or knowledge of the researcher, with obvious subjective colors. Referring to random sampling and non-random sampling, the ring cutter sampling means that a ring cutter is used for measuring the volume weight of soil, the existing ring cutter method soil sampling is manually operated, according to the standard of geotechnical test methods GB/T50123-2019, the inner wall of a soil cutting ring cutter used for testing is coated with a thin layer of vaseline, the cutting edge is downward, the soil cutting ring cutter is placed on the soil sample, and the soil sample is cut into a soil column slightly larger than the diameter of the ring cutter by using a soil cutting cutter (or a wire saw). And then vertically pressing the cutting ring downwards, pressing the edge while cutting until the soil sample extends out of the cutting ring, cutting off the residual soil at two ends and flattening.

When a tester presses the cutting ring, a gap is easily formed between the cutting ring and a soil body due to uneven force application, so that the soil body cannot be completely attached to the wall of the cutting ring, and the sampling effect is influenced; some experiential testers adopt the beating disk cover to act on the ring cutter to enable the ring cutter to descend, but the phenomenon of slipping easily occurs during beating, so that the ring cutter cannot be stressed uniformly vertically, the sampling effect is also influenced, the ring cutter is abraded seriously by always beating, the service life of the ring cutter is shortened, and the experimental result is influenced.
