Background
When shearing and consolidation tests are carried out in a laboratory, undisturbed soil is difficult to obtain in general, and a disturbed soil sample is required to be used for the tests. The geotechnical test method standard (GB/T50123-2019) provides three methods for preparing disturbed soil samples: sample hitting method, compaction method and sample pressing method.
The sample impacting method presses soil into the cutting ring through the impacting method, and the homogeneity of the soil sample, the structure of the soil body and the related physical and mechanical properties are influenced by the repeated impact action in the impacting process. The compaction method comprises the steps of compacting the soil sample to the required density, pushing out the soil sample by a soil pusher, pressing the soil sample into a cutting ring, and flattening two sides to obtain a sample. The sample pressing method compresses the soil sample with the specified mass to the specified volume by applying pressure, reduces the disturbance to the sample and has good sample preparation effect. Due to the lack of special equipment, the sample presser prepared by the sample presser has the problems of easy variability of instruments, uneven soil sample in a cutting ring, unfavorable demoulding, need of customizing sample pressing power and the like. The ring cutter sample pressing device solves the problems in the disturbed soil sample pressing process to a great extent.
