Sample layering treatment device for detecting argillaceous soil core column sample

Abstract

The invention provides a sample layering treatment device for argillaceous soil core column sample detection, and belongs to the technical field of geological survey, the sample layering treatment device comprises a sample placing part and a slitting and dividing part which are matched for use, and the slitting and dividing part is used for slitting and dividing a core column sample into independent sample units; the slitting and dividing part comprises a plurality of slitting discs which have an anti-sticking function and expand gaps between adjacent independent sample units to facilitate taking of the independent sample units, a radial limiting shaft is rotationally connected to the processing seat, middle connecting pieces are connected to the slitting discs, and the slitting discs are axially connected to the radial limiting shaft in a sliding mode through the middle connecting pieces. According to the sample layering treatment device for detecting the argillaceous soil core column sample, the sample slitting and dividing treatment efficiency and the slitting precision are effectively improved, the whole slitting process has the advantages of being high in stability and good in cut sample quality, the geological structure can be known by directly observing the sample in the slitting process, and the sample is fully and effectively utilized.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a sample layering processing device for detecting muddy soil core column samples. Background technique [0002] Argillaceous soil core pillar samples are generally cylindrical samples obtained by drilling and coring methods, which are often used in the field of geological survey. It is a very effective geological survey method to understand the specific conditions of the soil, and at the same time, the distribution of the geological structure can be understood through direct observation of the muddy soil core column samples. [0003] Because the muddy soil core column sample is generally a long and complete column when it is taken out of the formation, it is very inconvenient for detection and analysis, so before the detection and analysis, the samples will be divided into relatively independent and easy to detect and analyze according to the needs of the detection. th...

Problems solved by technology

[0004] The Chinese utility model patent with the application number CN202022415130.5 discloses a soil profile sample cutting device. The cutting device first fixes the soil sampling cylinder containing the soil sample by using a clamping assembly, and then uses a cutting wire to slowly push it out. Cutting the soil outside the borrow barrel has the advantages of stable soil cutting and low sample damage rate, but it can only obtain one independent sample unit at a time, the cutting efficiency is low, and it cannot be cut during the cutting process. By directly observing the soil samples to understand the geological structure, not only the utilization rate of the soil samples is reduced, but also the samples cannot be divided into layers according to the geological structure, which correspondingly reduces the representativeness of the independent sample units after division.

[0005] In view of the above problems, the existing sample division will directly divide the soil core column samples through manual cutting tools, which can not only understand the distribution of geological structure through direct observation, but also flexibly divide samples according to the geological structure. However, the efficiency of cutting and dividing is low, and it is easy to affect the quality of sample units due to manual operation errors and errors in the process of cutting soil core samples.
