Deep layer section soil sampler and sampling method thereof

Abstract

The invention relates to a deep layer section soil sampler and sampling method thereof, belonging to the ecologic study field of soil science, environmental science, and the like. The invention comprises an inverted triangular pyramidal main sampler, a seal sheet, a fixer and a tripod, the transversal surface of the main sampler is an equilateral right-angled triangle, a longitudinal opening is arranged along the bevel edge of the main sampler, the sealing strip fits the longitudinal opening, the upper end of the main sampler and the upper end of the sealing strip are respectively provided with an extension piece, the two adjacent right-angle sides of the main sampler are respectively provided with a connecting round hole, the sidewall of the sealing strip is provided with a connecting hole corresponding with the connecting round hole; the fixer is arranged in the interior of the upper part of the main sampler and is respectively connected with the main sampler and the sealing strip by a strengthened screw; the upper end of the fixer is provided with a round ring; and the lower end of the tripod is connected with an engineering pulley and the end part of the engineering pulley is connected with a hook. The invention has the characteristics that disturbance on soil is small, a mass of soil samples can be obtained, soil samples can be collected quantitatively in constant height, and soil is easy to separate from the sampling device.

Description

technical field [0001] The invention belongs to the fields of ecological research such as soil science and environmental science, and is suitable for the technical field of collecting deep soil profile samples. Background technique [0002] Soil has a very important research status in many disciplines such as soil science, environmental science, geology, geotechnical science, and ecology. It is very important to collect scientific soil samples according to the purpose of the experiment. During the collection of soil samples, researchers try to keep the soil as undisturbed as possible, and hope to learn more about the deep profile of the soil. Many soil studies include the study of deep soil samples. In the collection of deep soil samples, how to reduce the interference to soil samples and minimize the amount of earth excavation to obtain deep soil samples has been a problem that has puzzled researchers for a long time. [0003] In the process of collecting deep soil samples...

AI Technical Summary

Problems solved by technology

[0004] 1. Traditional soil samplers are mostly closed or semi-closed systems. When the sampler is driven into or pulled out of the soil, due to the twisting and extrusion of the sampler, it is easy to cause the cracking, compression and compaction of the soil layer and disturb the soil. state, which affects the authenticity of sampling;

[0005] 2. Sampling with ordinary samplers, most of them can only collect surface soil samples, and cannot collect deep soil samples in situ;

[0006] 3. The amount of soil taken is low, which cannot meet the test application of multiple indicators;

[0007] 4. When collecting deep soil samples, it is necessary to destroy a large amount of soil and dig deep pits to obtain soil samples, which is time-consuming, laborious and destructive;

[0008] 5. Traditional soil collectors cannot collect deep sections of soil samples such as sandy land, muddy land, and wetland
