Problems solved by technology

[0002] Every year, many land subsidence disasters occur all over the country, especially in karst areas, causing serious losses to people's lives and property. Since karst soil caves are all below the ground and have different buried depths, It is extremely concealed, which brings great difficulties to disaster monitoring
[0003] At present, the monitoring methods used for ground subsidence disasters mainly include geological radar (GPR), TDR (BOTDR) technology and water (air) pressure monitoring. ) pressure monitoring and it is difficult to draw more accurate conclusions, and the three methods also have the defect of poor operation convenience

Abstract

The invention discloses a ground surface collapse monitoring method, an induction ring and a magnetic sensor are sequentially hoisted in a monitoring cave, after a ground surface collapse disaster appears, the monitoring cave is damaged, the induction ring loses supporting and falls off, in the falling process, a permanent magnet arranged on the induction ring overlaps a detection area of the magnetic sensor, and after the magnetic sensor induces the falling motion of the induction ring, a user can know that the ground surface collapse disaster occurs already. The invention further provides a ground surface collapse monitoring device which can achieve the monitoring method. The ground surface collapse monitoring device and method have the advantages that needed hardware is simple, the device is convenient to arrange, data processing is easy and convenient, and monitoring results are accurate and reliable.

Description

technical field [0001] The invention relates to a geological disaster monitoring technology, in particular to a ground subsidence monitoring device and monitoring method. Background technique [0002] Every year, many land subsidence disasters occur all over the country, especially in karst areas, causing serious losses to people's lives and property. Since karst soil caves are all below the ground and have different buried depths, It is extremely concealed, which brings great difficulties to disaster monitoring. [0003] At present, the monitoring methods used for ground subsidence disasters mainly include geological radar (GPR), TDR (BOTDR) technology and water (air) pressure monitoring. ) pressure monitoring and it is difficult to draw more accurate conclusions, and the three methods also have the defect of poor operation convenience. Contents of the invention [0004] Aiming at the problems in the background technology, the present invention proposes a ground sub...
