Soil sample making device and usage method thereof

Abstract

The invention discloses a soil sample preparation device and a using method thereof, belonging to the field of soil engineering experiment research. It mainly includes sample preparation cylinder, ring knife and base plate. The sample preparation cylinder is a half-type cylinder, and the two cylinder pieces are assembled together by a clamp. At the splicing of the tube pieces, there is a groove on the side of the tube piece on one side, and there is a rubber strip in the groove, which can ensure that the seam is tightly bonded after splicing. The inner wall of the sample preparation cylinder is provided with a ring knife positioning groove, a plurality of ring knives can be placed in the ring knife positioning groove, and there are backing rings between adjacent ring knives. The device can prepare multiple ring knife samples at one time, which is fast and efficient.

Description

Technical field [0001] The invention relates to the field of geotechnical experiment research, in particular to a soil sample preparation device and a use method thereof. Background technique [0002] In the process of indoor geotechnical experiments, it is often necessary to make ring knife samples (soil samples for short). Under normal circumstances, it is necessary to pour the sample soil into the sample tube in batches, compact it in layers, and then push the compacted soil out of the sample tube. Then, with the cutting cooperation of the soil cutter, use a ring knife to obtain the belt The sample of the ring knife in order to obtain the sample of the ring knife for the experiment. Push the prepared soil out of the sample preparation tube, which will cause a disturbance to the soil sample; then use the ring knife to sample, the soil sample is prone to squeeze deformation; it may also prevent part of the soil sample from being in close contact with the inner wall of the ring ...

AI Technical Summary

Problems solved by technology

Push the prepared soil out of the sample preparation cylinder, which will cause a disturbance to the soil sample; then use the ring knife to sample, the soil sample is prone to extrusion deformation; it may also prevent some soil samples from being in close contact with the inner wall of the ring knife

These factors will have a great impact on the test results, and it is urgent to improve the existing devices.
