Abstract

The invention discloses a toppling deformation body monitoring and early warning device and a toppling deformation body monitoring and early warning method, and relates to the technical field of slope monitoring, and the main points of the technical scheme are that the toppling deformation body monitoring and early warning device comprises a processor, a main substrate and two curved-surface substrates; the two curved-surface substrates are distributed on the two sides of the main substrate, and the sphere centers corresponding to the two curved-surface substrates are located below the two sides of the main substrate in an inclined mode. A plurality of strain gauge sensors are arranged on the same side surfaces of the main substrate and the two curved-surface substrates; and the strain gauge sensors are electrically connected with the processor. When toppling deformation occurs, the main substrate and the two curved surface substrates can adaptively generate cooperative deformation, a row of strain gauge sensors start detection at the same time to obtain deformation data under corresponding dimensions, and after the data are subjected to simulation analysis, conversion and other processing, a detection result directly representing the toppling deformation condition can be directly obtained. Efficient and simple on-line monitoring of toppling deformation is achieved, the overall structure is convenient to install, maintain and operate, and the application cost is low.

technical field [0001] The invention relates to the technical field of slope monitoring, more specifically, it relates to a monitoring and early warning device and a monitoring and early warning method for a toppling deformed body. Background technique [0002] The toppling deformation body is a typical deformation phenomenon of the anti-dipping layered rock slope. Under the influence of human engineering activities, etc., the deformation of the slope will be further aggravated. As the deformation continues to develop, it will cause collapse or shallow Local landslide geological disasters, and finally produce a ladder-like sliding and cracking landslide.

The commonly used monitoring methods are to use theodolite, level, total station and other measuring instruments to regularly measure the monitoring piers poured on the toppling and deformed body, and then...

Problems solved by technology

[0003] At present, there are few studies on the monitoring and early warning technology of the toppling deformed body. The commonly used monitoring methods are to use theodolite, level, total station and other measuring instruments to regularly measure the monitoring piers poured on the toppling and deformed body, and then analyze the deformation of the toppling and deformed body. According to the development situation, the problems of this method are: large amount of field work, inconvenient monitoring in unfavorable weather and night, low accuracy, can not accurately obtain the deformation depth and bending angle of the dumped deformed body, and cannot provide uninterrupted Monitoring and timely warning

In addition, there is also a technology that combines strain gauge sensors with some orientation and angle detection sensors to realize the monitoring of dumped deformation objects. Due to the large number of electronic products required, the workload and difficulty of installation and regular maintenance increase; at the same time, The processing and conversion of various data is relatively complicated, which is not conducive to the large-scale monitoring of dumped deformed bodies
