The invention discloses an experimental device for monitoring the law of solute migration in pore water. Including: a recyclable and adjustable pore structure medium model, a pollution injection device, a pressure sensor and a conductivity sensor for measuring the characteristics of water flow and solute migration in the experimental device, and a data acquisition system for automatically reading data. The detachable experimental device is characterized in that it includes an acrylic plate with an arc track (front and rear sides), and left and right side cut-off plates and a bottom plate with a cut-off device. The device has a reasonable structure and strong operability, and can realize the replacement of the simulated medium, change the size of the model, and adjust the surface gradient of the medium. The sensors in the model device and the integrated inspection instrument system can efficiently and automatically read the water head and solute concentration information of the entire system, and automatically read the data.
Description
technical field [0001] The invention relates to a detachable and self-adjustable model size experimental device for monitoring the migration law of pore water solute, which belongs to the technical field of groundwater simulation. Background technique [0002] The study of solute transport in groundwater has been very mature in the theory of dealing with simple problems, and the focus of research has shifted to problems under complex or special conditions. The foundation conditions and underground water permeability conditions encountered in actual projects are often complex and changeable. Even if the theory has been proved to be mature or even perfect under simple conditions, it is often difficult to directly play a role or be reliable under complex or special conditions. not tall. [0003] The existing models of solute transport in porous media of groundwater are few in number, and often have a single size, which cannot be adjusted. At the same time, the porous medium i...
