Abstract

The invention discloses a monitoring and early warning device and method for the red line of water level in karst subsidence areas, comprising: a base; support rods, four support rods are respectively fixedly connected to the four corners of the bottom of the base; a control mechanism, the control mechanism is connected by screws on the rear side of the top of the base; guide rails, the two guide rails are detachably arranged at both ends of the left side of the base, and the bottom of the inner cavity of the guide rails on the front side is provided with card slots from left to right; reinforcing ribs, the The reinforcing rib is detachably arranged on the left side of the guide rail; the slider is plugged into the left side of the inner cavity of the guide rail. In actual use, the present invention can mechanically monitor the height of the water level of the subsidence pit without the need for staff to approach the subsidence pit, greatly improving the safety, and reducing the labor intensity of the staff, saving manpower, and realizing the early warning of the red line of the subsidence pit water level Real-time monitoring is more conducive to the use of water level monitoring.

Description

technical field [0001] The invention relates to the technical field of karst subsidence monitoring, in particular to a device and method for monitoring and early warning of water level red lines in karst subsidence areas. Background technique [0002] Karst collapse is a three-phase mechanical equilibrium system of solid, liquid and gas formed by karst caves, overlying sediments, and groundwater. When the groundwater level fluctuates to a certain extent, the balance is broken, and the overlying loose sediments suddenly collapse, forming a large top and bottom small. Conical collapse pit. The groundwater movement is the dynamic condition for the collapse, the groundwater level sharply changed zone is the sensitive area for the collapse, and the change of hydrodynamic conditions is the main trigger factor for the collapse. The main causes of rapid changes in hydrodynamic conditions are rainfall, reservoir water storage, underground water filling, irrigation leakage, severe dr...
