Erosion Effect on Non-Darcy Hydraulic Characteristics of Limestone and Mudstone Mixture

Procedure 1

Test preparation: First, the seepage pipeline is connected, and the data acquisition system is adjusted to make it work normally. After this, the double-acting hydraulic cylinder is filled with water. Then, the broken sample is put into the erosion unit, and the water is injected into the pipeline to exclude air in the pipeline and saturate the sample. Subsequently, the piston is placed and the initial height of the sample is recorded.
