Background
In soil detection, it is often necessary to prepare a sample of undisturbed soil (undisturbed) using a cutting ring to test for such metrics as volume weight, compression, shear and penetration of the soil.
In the prior art, the preparation of undisturbed soil samples mostly adopts a manual sample preparation mode, and the specific method comprises the following steps: firstly, placing a ring cutter with vaseline coated on the inner side above an undisturbed soil sample with a thin layer on the top surface removed, then placing a pressing ring on the ring cutter, vertically pressing the ring cutter by pressing the pressing ring by bare hands, continuously removing redundant soil materials at the edge of the undisturbed soil sample by using a soil cutting cutter in the pressing process, reducing friction between the undisturbed soil sample and the outer wall of the ring cutter, avoiding influencing parameter measurement due to compaction of the lower part of the undisturbed soil sample, pressing and cutting simultaneously until the undisturbed soil sample extends out of the ring cutter, and finally cutting residual soil at two ends of the ring cutter to be flattened. The sample preparation method has higher technical experience requirements for operators, and a small gap is easily formed between the cutting ring and the soil body due to uneven force application in the process of pressing the cutting ring, so that parameters such as density, compression modulus and the like of the soil are distorted.

Although the ring cutter can be pressed into the original soil sample in a uniform stress manner. However, the principle is that the lifting seat is driven by the jack to rise, so that the undisturbed soil sample in the sample box is extruded into the cutting ring at one time. On one hand, the jack is adopted, so that the use cost is high; on the other hand, as the undisturbed soil sample is extruded into the ring cutter, the lower part of the prepared undisturbed soil sample is compacted, the sample preparation quality is poor, and the accuracy of measuring parameters such as the volume weight, the void ratio and the like of the subsequent soil is further affected.
