Liner type undisturbed soil fetcher with bracket

Abstract

The invention relates to a soil sampler, and particularly relates to a liner in-situ soil sampler with a bracket. The soil sampler comprises a soil sampler main body, a fixing sleeve, a screw, a screw fixer, a triangular support bar, and a disc-shaped base, wherein the fixing sleeve is arranged on the soil sampler main body; the screw with a spanner at one end is connected to the fixing sleeve; the screw fixer is sleeved on the screw; the triangular support bar is connected to the screw fixer; and the disc-shaped base playing fixing and limiting roles on the soil sampler body is arranged at the lower end of the triangular support bar. The soil sampler is used for collecting different depths of soil analysis samples, not only suitable for in-situ soil sampling for scientific research, but also suitable for soil test sampling, and suitable for the departments for scientific research, education and production related to soil and geotechnique.

Description

technical field [0001] The invention relates to a soil fetcher, specifically a liner-type undisturbed soil fetcher with a bracket, which is used to collect soil analysis samples at different depths, and is not only suitable for sampling undisturbed soil for scientific research, but also suitable for Sampling for geotechnical tests, suitable for scientific research, teaching and production departments related to soil and geotechnical engineering. Background technique [0002] Soil extractor is used as a kind of auxiliary tool for soil analysis sampling and geotechnical test sampling as a kind of collection of soil analysis samples, which has been widely used by related scientific research, teaching and production departments. The soil extractor in the prior art, for example, the patent No. Due to its unreasonable structure, there are many shortcomings and deficiencies in the prior patent application, which are specifically manifested in: ①, the design of the soil sample jacke...

[0002] Soil extractor is used as a kind of auxiliary tool for soil analysis sampling and geotechnical test sampling as a kind of collection of soil analysis samples, which has been widely used by related scientific research, teaching and production departments. The soil extractor in the prior art, for example, the patent No. Due to its unreasonable structure, there are many shortcomings and deficiencies in the prior patent application, which are specifically manifested in: ①, the design of the soil sample jacket pressing device is unreasonable, the compressive capacity is weak, and it is difficult to take out after being pressed into the soil ; ②, although the horizontal air bubble for leveling is set, there is no horizontal fixing device, which is difficult to realize in the actual operation process; ③, the connection between the internal thread drill pipe holder and the supporting triangular bracket is not conducive to the rapid installation and fixing of the instrument

[0003] In order to solve the above problems, the applicant has developed a liner-type direct pressure undisturbed soil fetcher, and applied for an invention patent, the patent application number is 201210403091.4. This soil fetcher is mainly used to collect soil samples of about 40cm-60cm. Taking soil from a large section, such as collecting undisturbed soil for scientific research and teaching over 100cm and soil samples for deeper geotechnical tests, due to limited manpower, it is difficult to take soil
