Abstract
The invention provides an underground water flowing property detection device and detection method, and belongs to the technical field of underground water detection. The detection device comprises afirst mounting piece, a direction indicating piece, a deflection piece, an ultraviolet light source and a camera shooting piece. The deflection piece is connected to the first mounting piece and is used for deflecting under the action of water flow. The direction indicating piece is arranged on the first mounting piece, and the indicating direction of the direction indicating piece is kept unchanged all the time. Both the direction indicating piece and the deflection piece are provided with fluorescent marks. The ultraviolet light source and the camera shooting piece are both arranged on the first mounting piece, and the camera shooting piece is used for recording the positions of the direction indicating part and the deflection piece and measuring the water flow direction of underground water to be measured through the included angle between the direction indicating piece and the deflection piece when the deflection piece rotates to be parallel to the flow direction of the undergroundwater to be measured. The detection device is simple in structure, the detection method is convenient and fast, complex calculation is not needed, and radioactive elements or other tracers do not need to be independently added in the measurement process.
Description
technical field [0001] The invention relates to the field of groundwater detection, in particular to a groundwater flow performance detection device and detection method. Background technique [0002] Groundwater seepage velocity and flow direction are not only two important dynamic parameters in the study of groundwater seepage field, but also the main parameters for determining hydrogeological parameters such as aquifer permeability coefficient and seepage flow. The traditional method of measuring groundwater flow velocity and flow direction is to arrange boreholes along the flow direction on the basis of understanding the geological conditions of the studied area and the approximate groundwater flow direction, and then measure the groundwater flow velocity through pumping tests. The method has a large workload, a long construction period, and complicated processes. [0003] In view of this, this application is proposed. Contents of the invention [0004] One of the ob...
