Measuring device and method for dynamically monitoring scouring process of sluice channel of barrier body

Abstract

The invention relates to a measuring device and method for dynamically monitoring the scouring process of a sluice channel of a barrier body. The measuring device comprises a sluice channel two-bank rock-soil body measuring assembly, a sluice channel bottom plate measuring assembly, a fixed suspension assembly and a data receiving terminal. The fixed suspension assembly stretches across the drainage groove, wherein the two ends are fixedly arranged outside the rock-soil body scouring and widening areas on the two banks in the drainage process; the sluice channel two-bank rock-soil body measuring assembly and the sluice channel bottom plate measuring assembly are connected with the data receiving terminal through data transmission lines. The scouring process of rock and soil on water on the two sides of the sluice is dynamically detected through rock and soil body measuring assemblies on the two banks of the sluice; the scouring process of the underwater bottom plate of the sluice is dynamically detected through the sluice bottom plate measuring assembly; therefore, dynamic monitoring of the dynamic scouring process of the underwater bottom plate of the sluice and the change process of rock-soil bodies on the two banks of the sluice in the whole drainage process is achieved, and the real-time online monitoring of overwater and underwater parts is realized.

Description

technical field [0001] The invention relates to the technical field of dam body safety monitoring, in particular to a measuring device and method for dynamically monitoring the scouring process of a dam body discharge channel. Background technique [0002] The dam is an accumulation body that blocks the river due to landslides, collapses and debris flows on both sides of the river due to earthquakes and precipitation under certain geological and landform conditions. Due to its special material composition and structural characteristics, damming bodies are prone to collapse, and most of the damming bodies will eventually collapse. [0003] In order to reduce or prevent flood disasters caused by the collapse of dams, it is necessary to carry out risk assessment of dams in the disaster area, and timely dispose of high-risk dams. In the treatment of general barrier lakes, a combination of engineering measures and the transfer of downstream personnel to avoid danger is often ado...

[0005] At present, for the monitoring of the excavation chute, more high-definition cameras are used to take high-definition cameras on the water part, and then the high-definition video and high-definition photos are processed to restore the scouring process of the water part of the chute during the drainage process to the greatest extent; but For the monitoring of the underwater part of the discharge tank, due to the high flow rate of the discharge water and the difficulty of installing the measuring device, there is no reliable monitoring and measuring device to reflect the washing process of the underwater part of the discharge tank, especially the bottom plate of the discharge tank
