Problems solved by technology

However, during the sampling process, due to the disturbance of the edge of the soil sample due to the uneven application of human force, and the verticality of the soil sample cannot be guaranteed due to factors such as terrain and soil quality, the soil sample cannot be close to the original state due to artificial vibration during soil sampling.

Abstract

The invention discloses a support rotary type undisturbed soil sampler, which comprises a detachable handle, an external threaded drill rod, a triangular support, a drill rod holder with internal threads, a diameter adjustment plate and a holder, and a soil sample jacket pressed into the Plate, soil sample jacket fixing ring, cutter, roller type fixing device, tripod fixing rod, horizontal air bubble, soil sample container and so on. The invention has the advantages of small volume, convenient assembly and disassembly, simple structure, low manufacturing cost and portability. It is not only suitable for soil engineering test sampling, but also meets the undisturbed soil sampling for scientific research. The whole process of taking soil can be carried out under stable and constant pressure, the operation is more convenient and reasonable, the drilling and sampling are integrated, and the diameter and height of the original soil sample can be adjusted according to the needs; Close to the original state of the soil, suitable for soils with different densities and soil layers with sand and pebbles.

Description

technical field [0001] The invention relates to a sampler, in particular to a stand-rotating undisturbed soil sampler. Background technique [0002] Most of the existing earth borrowers adopt the direct pressing type, the hammer pressing type and the pressing and rotating type when borrowing soil. However, during the sampling process, due to the uneven application of artificial force, the edge of the soil sample is disturbed, and the verticality of the soil sample cannot be guaranteed due to factors such as terrain and soil quality. . The size of the soil sample taken cannot be adjusted, and different types of soil extractors are needed to adjust. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a stand-rotating undisturbed soil sampler, which overcomes the disturbance of uneven forces due to artificial pressurization, hammering, etc., and can obtain undisturbed undisturbed geotechnical and undisturbed soil for soil property tests. In...
