Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cutting ring soil sample preparation, particularly relates to a cutting ring soil sample soil returning device. BACKGROUND

[0002] The cutting ring is a short tubular steel product with a blade at one end, which is a commonly used instrument for taking undisturbed soil samples for experiments, such as container weight, compression, shear and permeability tests.

[0003] Manual sample preparation requires high technical experience of the operator. During the pressing process of the cutting ring, uneven force application can easily cause gaps between the cutting ring and the soil body, resulting in incomplete adhesion of the soil body to the cutting ring wall, and further leading to deviations in test values such as density, compression amount, and permeability coefficient. Moreover, for high-density clay soil, a large amount of working time is required, which brings inconvenience to work.

[0004] The existing patent (publication number: CN210400988U) provides a test device for preparing undisturbed soil cutting ring samples and disturbed soil block cutting ring samples. The device uses high-precision mechanical force transmission to press, avoiding the incomplete test samples caused by unstable manual pressure during the previous cutting ring sample preparation process, saving time and ensuring the accuracy of the test results. The cutting ring clamp can be easily replaced through the clamp fixing bolt, and the soil sample progress observation port can be easily observed to avoid repeated sample preparation due to insufficient cutting ring footage.

[0005] To solve the above problems, the existing patent provides a solution. However, the cutting ring sample preparation device is usually used in the laboratory, and the loose soil sample after treatment is loaded into the cutting ring. The required soil sample is prepared through compaction and other methods. After the compaction step, the soil sample needs to be taken out of the sample preparation device. This part is mostly manually operated by artificial manual operation. During the soil sample transfer process, the sample preparation device may be offset, causing edge damage during the soil sample transfer process and affecting subsequent experiments.

[0006] Therefore, a cutting ring soil sample soil returning device is proposed. UTILITY MODEL CONTENTS
