Problems solved by technology
On the one hand, this leads to a large workload; on the other hand, due to the slow speed of changing the position of the measuring electrode, such a long time will lead to changes in the salt concentration and distribution of the groundwater, making the electric field on the ground during the process of changing the position of the measuring electrode The distribution is also changing, which makes the equipotential points found on different survey lines not at the same time as the equipotential points on other survey lines, resulting in inaccurate measurements of water flow velocity and direction

Description
technical field [0001] The invention relates to a groundwater flow direction measuring device and method, belonging to the technical field of groundwater measurement. Background technique [0002] The charging method is used to measure the flow direction and velocity of groundwater, such as Figure 1-Figure 3 , the principle is to drill a hole in the ground, drill the hole into the aquifer, and then apply an electric field on the ground with the hole as the center of the circle, add a salt bag to the aquifer in the hole, and the ground electric field before and after applying the salt bag The characteristics are observed and studied, so as to obtain the flow direction and velocity of groundwater. When the existing charging method is implemented, a power supply, a potentiometer, a pair of power supply electrodes and a pair of measurement electrodes are used. The power supply electrodes are connected to the power supply to apply an electric field centered on the ground, and th...
