Abstract

The invention discloses a confined aquifer dispersion test device and a test method thereof. The device comprises a pressure testing pump, a drill pipe, a hydraulic plug, a one-way valve, a high-pressure pipe, a pressure water pump, a monitoring probe, a direct reading cable and a data receiving device. The design that the drill pipe assists in connecting the hydraulic plug and the one-way valve is adopted, the hydraulic plug can effectively isolate underground water at upper and lower parts of the set depth for release of a tracer in a dispersion test main drill hole, the tracer is injected under pressure, accurate control of the injection depth and injection dose of the confined aquifer tracer can be realized, accuracy and reliability of confined aquifer dispersion test data can be guaranteed, the test data can be recorded automatically, and the test efficiency and accuracy can be greatly improved. The device can be applied to all drilling dispersion pressure tests.

Description

technical field [0001] The invention relates to the fields of hydrogeology and environmental protection, in particular to a pressure-bearing aquifer dispersion test device and a test method thereof. Background technique [0002] The purpose of the dispersion test is to study the spatio-temporal variation of the concentration of pollutants when they migrate in the groundwater, and to obtain the dispersion parameters for the quantitative evaluation of the groundwater environmental quality through the test. [0003] At present, the usual tracers are put into the water surface and underwater, and the samples are taken and titrated at the same depth in the observation hole or the detection instrument monitors the temporal and spatial variation trend of the tracer concentration, and then the dispersion parameters of the groundwater are determined. However, when encountering deep buried confined water, due to the high pressure of the water head, the existing tracer injection device...
