Product overview
This experiment complies with the SL237-056-1999 Test Code for Coarse grained Soil in Hydroelectric and Hydraulic Engineering and the GB/T50123-2019 Soil Test Standard. The experimental method uses infiltration water flow from bottom to top, suitable for coarse-grained soil, to determine parameters such as permeability coefficient, dry density porosity, infiltration slope reduction, and seepage flow velocity of coarse-grained soil.
