Description
Technical Field
[0001] The utility model relates to the technical field of soil sample compaction, in particular to a novel ring knife soil sample compaction device. Background Art
[0002] Sample preparation for frozen soil direct shear test is one of the key steps to ensure accurate and reliable test results. Cylindrical soil sample preparation is very common in our frozen soil direct shear test. Under our experimental conditions, we can only use the most primitive method to process soil samples. The current method of processing soil samples is to put loose soil into a ring cutter and compact it layer by layer with a wooden hammer. During the compaction process, it is difficult to ensure that the soil is evenly stressed, especially at the junction of the soil and the ring cutter. This new invention effectively solves this problem. At the same time, it is difficult to remove the soil sample from the ring cutter in the traditional sample preparation method. This new invention also solves this problem. Utility Model Content
