Technical Field

[0002] Soil particle composition measurement is the process of determining the percentage of various particle groups in the soil's total mass through particle analysis. The pipette method is a classic method for soil particle composition testing. In this method, a specific amount of suspension is drawn up at a specific time and depth, dried, and weighed to determine the content of particles of different sizes.

[0003] Among existing Chinese utility models, the announcement number CN208968968U discloses a soil mechanical measurement device, comprising: a sedimentation cylinder having at least one through-hole provided on its cylinder wall, and a length measurement mark provided on the sedimentation cylinder; a sampling tube having a front end inserted into the through-hole of the sedimentation cylinder, placed horizontally, and a rear end extending outward from the sedimentation cylinder, the sampling tube located in the inner cavity of the sedimentation hole having at least one liquid inlet hole provided, and a liquid outlet hole provided at the rear end of the sampling tube; a drainage tube connected to the rear end of the sampling tube, the drainage tube having an on-off valve provided on the drainage tube; and a collection container, which is provided corresponding to the liquid outlet hole of the drainage tube and is used to receive the liquid solution flowing out of the drainage tube, and the collection container having a volume measurement mark provided on it. The measurement device of this utility model can accurately and quickly complete the sampling operation, thereby improving the detection accuracy.

Therefore, how to effectively sample soil solution at a specific depth without drilling additional holes in the sidewalls of the sedimentation tube is a key issue that needs to be addressed in the design of a soil particle composition measuring instrument.
