In the field operation link of the sand-filling density test, firstly, a flat surface is selected at a test site and cleaned, and the area of the flat surface is not less than that of the substrate. And then, the substrate is placed on a flat surface, and when the roughness of the surface is larger, the calibration of cone sand filling on site is carried out. The substrate is then placed back onto the cleaned surface and a hole is drilled along the hole in the substrate. During the punching process, the punched material should be taken out and put into a plastic bag at any time without evaporating water, and can be put into a large sample box. The depth of the test hole is equal to the thickness of the measured layer, but no lower layer material is mixed in, and finally all the chipped material in the hole is taken out. For the soil base or the base layer, the mass of the material can be weighed several times in order to prevent the water in the sample plate from evaporating. And finally, sequentially measuring the water content, filling sand and calculating.
