A kind of layered sample processing device for muddy soil core column sample detection

Abstract

The invention provides a sample layering processing device for muddy soil core column sample detection, which belongs to the technical field of geological survey, and includes a sample placing part and a cutting and dividing part used in cooperation with each other, and the cutting and dividing part is used to divide the core column sample. Divide into independent sample units, the slitting and dividing part includes several slitting discs with anti-sticking function and expanding the gap between adjacent independent sample units to facilitate its taking, the processing seat is rotatably connected with a radial limit shaft, An intermediate connecting piece is connected to the slitting disk, and the slitting disk is axially slidably connected to the radial limit shaft through the intermediate connecting piece. The sample layering processing device for muddy soil core column sample detection effectively improves the efficiency and cutting accuracy of sample cutting and dividing processing. The whole cutting process has the advantages of high stability and good sample quality after cutting, and the cutting During the process, the geological structure can be understood by directly observing the sample, so that the sample is fully and effectively used.

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.
