On the other hand, the invention also provides a sample preparation method, which adopts the ring-knife sample preparation device of the first aspect, as shown in fig. 9, and comprises the following steps:
s100, dividing the soil into a plurality of parts, wherein in the embodiment, the soil can be equally divided into six parts (four A-type samples and one B-type sample, wherein the B-type sample is two A-type samples) in a weighing mode;
s200, pouring soil materials into the cutting ring barrel group 10 according to batches, and performing layered compaction or compaction molding on the soil materials to a preset height (in the embodiment, the height of a type A sample is controlled to be 24mm, and the height of a type B sample is controlled to be 44mm), wherein layered joints are required to be planed;
s300, sequentially detaching the pile casing 40, the first snap ring 20, the first ring cutter cylinder 11 and the second snap ring 20 to expose the first ring cutter sample;
