Abstract

The utility model relates to a crevice medium current, solute transfer testing device, wherein a sensor and a sealing material are mutually connected in a test vessel whose bottom is provided with a saturated water inlet pipe and a water outlet pipe. The saturated water inlet pipe is provided with a valve to control the water intake flow, while the water outlet pipe is provided with a manometer and a consumption meter. The admitting pipe with a manometer is arranged between the test vessel and the pressurizer. The entrance end of the pressurizer is provided with a screw booster pump whose entrance end is connected with a liquor reservoir, and the sensor is fixed in the sensor fixing sleeve tube. Solving the problem that the previous testing device can only test the density and the pressure at the liquor input terminal and output terminal, the utility model allows to directly test the solution strength, pressure and temperature at each point in the crevice medium, and has the advantages of novel design, simple structure, multi-function, cost saving and enhanced accuracy of test thereby.

Description

Fissuted medium current, solute transfer test unit

Technical field

The utility model relates to a kind of fissuted medium current, solute transfer experiment test device of being used for, and belongs to underground water Detection Techniques field.

Background technology

At present, how the solute transfer rule in the pore media to be carried out test simulation with sand post or sand box model.Because the complicacy of fissuted medium, be used for studying that there is following shortcoming in the test system of groundwater flow and solute transfer rule in the fissuted medium: sample dimensions is very little, general several centimetres to tens centimetres; Can not directly record the magnitude of physical quantity of every bit in the fissuted medium, usually do chemical analysis and calculate its concentration from the solution output terminal collection solution of fissuted medium; Be difficult to the geometric shape of rock cranny is analyzed, thereby current and solute transfer in the crack under the different shape are carried out test simulation.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned various defective, designs a kind of device that is used for fissuted medium current, solute transfer experimental test, the Changing Pattern of concentration, pressure and temperature when crossing fissuted medium in order to measure flow of solution.Technical solution of the present utility model: its structure is that sensor and encapsulant join, they are located in the test specimen container, establish saturated water inlet pipe, rising pipe in the bottom of test specimen container, the valve of control flow of inlet water on saturated water inlet pipe, establish tensimeter, flowmeter on the rising pipe, establish water inlet pipe between test specimen container and pressurizer, on water inlet pipe, establish tensimeter, on the entrance point of pressurizer, establish the spiral boosting pump, the entrance point of spiral boosting pump links to each other with solution reservoir, and sensor is fixed in the sensor fixed sleeving.Advantage of the present utility model and effect are modern design, simple in structure, function is many, can only be before having solved by surveying the problem of solution input end and output terminal concentration and pressure, can directly record solution concentration, the pressure and temperature of each point in the fissuted medium, and provide cost savings, improved test accuracy.
