Problems solved by technology

In the traditional tracer method, since the tracer is mostly a dye or an electrolyte solution, a special dosing device is required, and the dosing point and the measurement location must be separated by a long distance, so it is difficult to design an integrated sensor to achieve continuous monitoring; The temperature field changes to determine the seepage velocity and flow direction. The fiber optic temperature measurement and seepage monitoring system is a typical representative of this type. Since the fiber optic temperature measurement and seepage monitoring system needs to lay optical fibers within the monitoring range, the cost is relatively high

Description

technical field [0001] The invention relates to the technical field of rock and soil seepage monitoring, in particular to a rock and soil seepage monitoring sensor and a preparation method. Background technique [0002] Seepage flow direction and flow velocity are very important parameters in the fields of geotechnical engineering and hydrogeology, and are also of great significance to the research of pollutant migration, oil and gas development, water and soil erosion and other related issues. In the traditional tracer method, since the tracer is mostly a dye or an electrolyte solution, a special dosing device is required, and the dosing point and the measurement location must be separated by a long distance, so it is difficult to design an integrated sensor to achieve continuous monitoring; The temperature field changes to determine the seepage velocity and flow direction. The fiber optic temperature measurement and seepage monitoring system is a typical representative of ...
