Description
Technical Field

Background
Because the undisturbed soil sample has structurality, the obtained undisturbed soil sample is often damaged to a certain degree due to the complexity of the undisturbed soil sample and a field soil sampling process. Therefore, in the field of geotechnical tests, remolded soil with relatively uniform properties is increasingly used to research the mechanical characteristics of soil bodies.
The triaxial test of the remolded soil sample is an important component in the soil test, and according to the relevant regulation of the soil test method standard (GB/T50123-1999), the preparation method of the remolded soil sample mainly comprises a sample hitting method and a sample pressing method. When the remolded soil sample is prepared by adopting a sample hitting method, firstly, a soil material with a certain water content is prepared, then, the soil material is placed into a sample hitting device to hit the sample until the soil material reaches a preset dry density, and finally, the remolded soil sample is prepared. The sample pressing method is that prepared soil materials are loaded into a sample pressing device through a sample pressing device, then a certain load is applied to the soil materials, and the soil materials are pressed to a preset dry density. The sample hitting method is time-consuming and labor-consuming in preparing the remolded soil sample, low in efficiency, and meanwhile, in order to enable the prepared soil sample to be compact and uniform, the sample hitting is often carried out in a layering mode, but the soil sample obtained by the layering sample hitting is easy to form an obvious interface, and the reliability of a test result can be directly influenced by the existence of the interface of the soil sample. And the compaction state and the final quality of the sample have great relation with the hand feeling of an operator, the quality of the samples in the same batch made by the same person is different, and the final test result is influenced by the uneven compactness of the soil sample. The sample pressing method overcomes the defects of low efficiency and interface of the sample hitting method, so the sample pressing method is widely applied, but the current sample pressing device has the main defects of high price, complex operation method and great influence of human factors. In addition, due to the special requirements of soil tests, a large amount of remolded soil samples are often required for experiments, and the methods cannot prepare the soil samples in batches.
