Tracer agent feeding device and using method thereof

Abstract

The invention discloses a tracer agent feeding device and a using method thereof. The tracer agent feeding device is used for monitoring the flow direction, the flow velocity and the underwater real-time temperature of underground water and can feed tracer agents at fixed points in an underground aquifer or underground water body environment suitable for feeding. An operation processor is used forreceiving the electric signal monitored by the tracer agent feeding device through a cable and issuing an operation instruction to the tracer agent feeding device. By means of the device, specific tracers (such as fluorescein sodium and rhodamine, selected according to needs) can be used for monitoring and observing the flow direction and the flow speed of underground water, and the hydraulic connection between the source throwing hole and the observation hole is judged. Meanwhile, the water temperature and the horizontal inclination angle can be monitored, the development condition of rock holes or fractures in the inner wall of a well hole can be observed in real time, the flowing condition of a tracer agent in the hole can be monitored, and reliable basic data and video image data areprovided for further scientific research.

Description

technical field [0001] The invention belongs to the application field of water resources and groundwater science and engineering, and in particular relates to a tracer injecting device and a using method thereof. Background technique [0002] In order to solve the problems of groundwater resource evaluation and groundwater movement and migration laws, people often roughly regard the underground aquifer as a homogeneous and isotropic seepage field, and schematically describe the groundwater flow direction and velocity according to the groundwater iso-level lines and streamlines. However, this is often quite different from the real situation. In the past, when people tried to inject tracers into confined aquifers or submerged aquifers in upwelling water, because there was no direction-finding device, a large number of observation holes were needed to know the direction of groundwater flow, which wasted time and effort; The inclinometer device requires a separate borehole to m...

Problems solved by technology

[0004] The existing Chinese patent CN201820478809-confined aquifer dispersion test device has the following disadvantages in the content recorded in the patent document: it is necessary to use a drill pipe to bring the hydraulic plug to the specified depth, and connect the high-pressure pipe and the pressure water pump at the same time. Deep confined aquifers are difficult to realize, requiring dozens or even hundreds of times of drill pipe (about 2 meters per time), long test time and high cost;

If the observation hole is upstream of the source hole, the tracer will not be observed, which will also cause the test to fail
