Automatic emergency measurement method and equipment for dynamic scour deformation of dam body drainage groove

Abstract

The invention discloses an automatic emergency measurement method for dynamic scouring deformation of a dam body drainage groove. It includes the following steps: step a: install the fixed-end fixed pile and the movable-end fixed pile on both sides of the dam body respectively; step b: place the downstream array displacement meter along the flow direction at the centerline position of the bottom of the drainage groove in the initial state; Place the array displacement gauge in the vertical flow direction on the top surface of the dam on the upstream side of the dam body; step c: connect the upstream end of the array displacement gauge in the downstream direction to the anchor through a cable chain, connect the binding point on the vertical flow displacement gauge to the anchor through a stay cable, and Throwing the anchor into the lake after counterweighting; Step d: Installing the first comprehensive collector, the first storage battery and a computer; Step e: Realizing automatic real-time monitoring of the evolution process of dynamic scouring deformation of the drainage tank. The invention has the advantage of realizing the automatic monitoring of the scour deformation evolution process of the dam body groove bottom and groove slope. The invention also discloses automatic emergency measurement equipment for dynamic scouring and deformation of the drainage groove of the dam body.

Description

technical field [0001] The invention relates to the technical field of emergency monitoring and early warning of dammed lakes, in particular to an automatic emergency measurement method for dynamic erosion deformation of a drainage groove of a dammed body. The invention also relates to automatic emergency measuring equipment for the dynamic scouring deformation of the drainage groove of the damming body. Background technique [0002] my country is one of the countries with the most frequent geological disasters in the world, especially in the western high mountains and valleys, where crustal deformation and seismic activity are relatively strong. Natural disasters such as landslides, debris flows and collapses can easily lead to accumulations blocking the river and forming damming bodies. , the water level in front of the dam forms a dammed lake with the gradual accumulation of incoming water. The gradual rise of the submerged water level of the dammed lake will cause huge i...

Problems solved by technology

[0005] However, at present, there is no effective and practical emergency monitoring equipment and measurement method for the dynamic scour deformation evolution process of the drainage channel of the dam body. Evolution calculations, collapse mechanism analysis, etc. provide key parameters on site, and it is difficult to provide real-time and effective scientific basis for emergency rescue and scientific decision-making on site
