Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] The invention provides a method for real-time monitoring of groundwater flow velocity and flow direction. A flexible pipe is arranged along the vertical direction, and a pendulum ball is connected to the lower end of the flexible pipe; the flexible pipe is put into groundwater; the pendulum ball is affected by groundwater circumvention resistance Displacement is generated, and at the same time, the flow resistance acts on the flexible tube to cause flexural deformation of the flexible tube; the horizontal displacement of the pendulum ball under the action of the flow resistance and the deflection direction of the pendulum ball on the horizontal plane are measured;

[0025] According to the horizontal displacement of the pendulum ball under the effect of the flow resistance, the groundwater horizontal velocity is calculated.

[0026] The buoyancy of the pendulum b...

Abstract

The invention provides a real-time monitoring method and a real-time monitoring system for velocity and direction of underground water current. The real-time monitoring system comprises a sleeve, a probe, a cable and a ground control system. A flexible pipe is arranged in the probe in a vertical direction. One end of the flexible pipe is fixed and the other end is provided with a swing ball which bears a circle resistance of underground water. Furthermore the circle resistance functions on the flexible pipe, thereby generating flexible deformation of the flexible pipe. Through an electronic compass and a light-sensitive component, a horizontal-direction displacement of the swing ball under the function of the circle resistance and a deflection direction (horizontal flow direction of the underground water) in a horizontal plane are measured. The real-time monitoring method and the real-time monitoring system are based on fluid mechanics (hydraulics) and mechanics-of-materials theories, and the circle resistance which is bear by the swing ball, the horizontal-direction velocity of the underground water, and the horizontal displacement of the swing ball satisfy a certain functional relationship, thereby obtaining the horizontal-direction velocity of the underground water through calculation.

Description

technical field [0001] The invention relates to a method and a monitoring system for real-time monitoring of groundwater flow velocity and direction, belonging to the field of hydrogeological parameter monitoring. Background technique [0002] Groundwater seepage has a significant impact on hydrogeological conditions, engineering geological conditions, and environmental geological conditions. Groundwater seepage fields play an important role in geological disasters such as landslides, debris flows, and ground subsidence; groundwater seepage also affects the hydrogeological conditions of underground structures, dam foundation piping leakage, and so on. In addition, groundwater seepage causes soil solute migration (inorganic salts, nutrients, pollutants, etc.), so groundwater seepage is also of great significance to soil restoration and agricultural science. To sum up, the monitoring of groundwater velocity and direction (main characteristic parameters of groundwater seepage ...
