Description

Technical Field

Background
The determination of the flow direction and the flow speed of the underground water has important significance for environmental monitoring, hydrogeology and natural resources. In the field of environmental monitoring, the pollution condition of underground water can be determined in time through accurate monitoring of the flow direction and flow rate of the underground water, and the condition of secret pollution discharge can be monitored in real time; accurate reference data can be provided for geological exploration and engineering construction through the flow direction and the flow velocity of underground water in the hydrogeological field; the flow velocity of underground water flow can be stopped in the field of natural resources to predict the water resource loss condition. The existing groundwater flow velocity measuring method can be roughly divided into two methods: the water pumping experimental method comprises the following steps: three drilling holes are arranged along the vertex of the equilateral triangle, the hole distance is dozens of meters to hundreds of meters, the flow direction of the underground water is calculated by measuring the height of the water level of each hole, and then the flow velocity of the underground water is calculated by a pumping test according to Darcy's law. The method has the advantages of large construction range, high engineering difficulty, long test period and large deviation between the final test result and the actual condition. (II) tracing method: the method is to use a substance in water or add a substance in water as a tracer, and detect the content of the tracer or water level levels in different wells to determine the flow rate and flow direction of underground water. The accuracy of the method is different according to different tracers, some tracers can achieve a relatively accurate effect, but the defects are obvious, namely the tracers need to be added into water or some tracers in the water are detected by means of chemical means and the like, and great inconvenience is obviously brought to measurement. Meanwhile, some tracers have certain pollution and are slightly deficient in the aspect of environmental protection. Generally speaking, the existing method for testing the flowing speed of underground water has the problems of low testing precision, large use limitation, high testing cost, low real-time performance and the like.
An effective solution to the problems in the related art has not been proposed yet.
