Karst subsidence area water level red line monitoring and early warning device and method

Abstract

The invention discloses a karst subsidence area water level red line monitoring and early warning device and method. The device comprises a base; supporting rods, wherein the four supporting rods arefixedly connected to the four corners of the bottom of the base correspondingly; a control mechanism which is connected to the rear side of the top of the base through screws; guide rails, wherein thetwo guide rails are detachably arranged at the two ends of the left side of the base correspondingly, and clamping grooves are formed in the bottoms of inner cavities of the guide rails located on the front side from left to right; reinforcing ribs which are detachably arranged on the left side of the guide rails; and sliding blocks which are inserted into the left side of the inner cavities of the guide rails. The water level height of the collapse pit can be mechanically monitored during actual use, workers do not need to get close to the collapse pit, safety is greatly improved, the laborintensity of the workers is reduced, manpower is saved, real-time monitoring of collapse pit water level red line early warning is achieved and water level monitoring use is better facilitated.

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...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a red line monitoring and early warning device and method for karst subsidence area, so as to at least solve the problems in the prior art that the water level monitoring of karst subsidence pits is dangerous, labor is wasted, and real-time monitoring cannot be achieved
