Abstract

The application relates to a bilaterally pressurized three-axis sample preparation device, belonging to the technical field of indoor geotechnical engineering of civil engineering disciplines. The bilaterally pressurized three-axis sample preparation device comprises seven parts of: a pressure mechanism, a pressure conducting mechanism, an upper pressing mechanism, a lower pressing mechanism, a sample preparation cylinder, an upper support mechanism and a lower support mechanism. According to the application, the three-axis sample preparation pressure and time can be intelligently controlled,so as to simulate an actual soil layer consolidation process; a plurality of samples can be shaped at a time, therefore, the sample preparation time and disturbance to soil samples are reduced; and the defect that a traditional sample cylinder is difficult to perform sampling is overcome, and the bilaterally pressurized three-axis sample preparation device has certain engineering applicability.

Description

technical field [0001] The application relates to a bidirectionally pressurized triaxial sample preparation device, which belongs to the indoor geotechnical field of the civil engineering discipline. Background technique [0002] With the increase of construction projects on soft soil foundations in coastal areas, the test of soft soil mechanical properties has become an important content in current civil engineering. Triaxial test is a common experimental method to measure the mechanical properties of soft soil. The sample is cylindrical with a diameter of 3.91cm and a height of 8.0cm. During the experiment, 3-5 standard samples need to be made to test 3-5 different The mechanical properties of soft soil under confining pressure. Usually, manual compaction is used to uniformly compact the soil sample to achieve the target soil sample compactness, and manual demoulding is used. Due to the low efficiency of making samples one by one, it is difficult to accurately control th...
