The present invention discloses a test apparatus for monitoring a crack-pipeline medium solute transport law. The test apparatus comprises a structure variable crack-pipeline medium physical model, a pressure sensor system, a conductivity monitoring system, an automated data acquisition system, and an image acquisition system for real-timely capturing a water flow movement process in the model, wherein the crack-pipeline medium physical model comprises a crack network, a pipeline, a corresponding gasket and a supply system, the pressure sensor system real-timely monitors the water head change conditions of each observation point in the model, the data acquisition system is connected with the pressure sensor system and the conductivity monitoring system through a polling instrument, real-timely records the data, and stores in a computer, finally the definition camera technology is assisted, and a colored solvent is added to the apparatus so as to intuitively understand the solute transport situation in the whole flow field. According to the present invention, the apparatus has characteristics of reasonable structure and strong operability, the human error can be effectively reduced through the automated data acquisition, and the test apparatus is suitable for the research on the cavern water solute transport law mechanism.
Description
technical field [0001] The invention relates to a visualization device for automatically monitoring the law of solute migration under the condition of variable cracks and pipeline structures, wherein the structural characteristics of the cracks and pipelines can be adjusted, and belongs to the technical field of groundwater detection. Background technique [0002] The pollution of karst water environment is intensifying, the conflict between social development and the environment is intensifying, and the safety of people's lives and property is seriously threatened. Due to the special geological conditions of the coexistence of fissures and pipelines in karst areas and their interconnection, karst water pollution has the characteristics of rapid diffusion and wide range of influence, which makes it very difficult to deal with karst groundwater pollution. Therefore, it is of great significance to explore the change law of solute migration in the fracture-pipe medium for the p...
