Description
Technical Field
The invention belongs to the field of frozen soil tests, and particularly relates to a frozen soil sample preparation, sample loading and sample unloading integrated device and a method thereof.
Background
In the unidirectional freezing test of frozen soil, the uniformity of a tested soil body has great influence on the formation rule of a cold-grown structure and partial freezing ice of a soil sample in a frozen state. At present, frozen soil samples are mainly prepared by a compaction method and a static pressure method. The compaction method is to make a soil sample with specific water content by using a compaction instrument, and the uniformity of the soil sample is difficult to control. The static pressure method is to compact the test soil sample by a press machine to discharge air bubbles in the sample, so as to ensure the uniformity of sample preparation. Static pressure method has no specific device at present, and different devices and sample preparation methods are different.
In the process of preparing the soil sample by adopting the static pressure method, the key point of uniform sample preparation is how to ensure that the pressure head of a jack or a press machine is not eccentric. Because the pressure head is slightly smaller than the diameter of the sample preparation cylinder, the pressure applied by the pressure head is easy to deviate from the central axis of the soil sample to cause eccentricity, and the soil sample is easily extruded unevenly from the periphery of the pressure head under the action of the eccentric pressure; meanwhile, the pressure of the pressure head can act on the sample preparation barrel, so that the stress of the soil sample is reduced, and the sample preparation barrel is possibly crushed. In addition, when a jack is used for jacking a sample from a sample preparation cylinder to a test tank and detaching the sample from the sample preparation cylinder, the eccentricity easily causes uneven stress of the soil sample, and further causes the change of the shape of the soil sample or the generation of cracks and the like, thereby greatly influencing the proceeding of the test process.
