Problems solved by technology

[0002] At present, the internal hidden dangers of embankments and the single problem of detection, detection and monitoring technology are more prominent, which poses a greater threat to the safety of flood control and anti-alliance projects in the watershed. Wave wall and other massive revetment projects, but the traditional project management methods and monitoring technology can no longer fully meet the needs of project safety management, and the flood control safety network monitoring and early warning equipment and technology for a large number of embankment risk workers around the world are almost blank

Embodiment 1

[0150] An emergency early warning system for embankment dangers, which specifically implements the layout section DF-I. Instruments are arranged in the section area to meet the surface displacement of the slope surface on the backwater side of the embankment, the infiltration line of the dike body and embankment foundation, the water level of the Yellow River, and the horizontal displacement of the test section through GPS. For the monitoring of settlement deformation, dike settlement and video monitoring are not carried out on this section, and the instruments used include soil displacement meters, piezometers, radar water level gauges, lightning rods, solar panels, and information collection boxes;

[0151] Wherein, the construction method of monitoring the surface displacement of the slope surface on the back side of the embankment has the following steps:

[0152] (1) Check the package, including soil displacement sensor, measuring rod and measuring rod protection tube, end...

Embodiment 2

[0179] An emergency early warning system for embankment danger, specifically implementing the layout section DF-Ⅱ, where CNSS receivers are arranged in the area of ​​the section, and the section is a monitoring station for the horizontal displacement and settlement deformation of the test section through GPS. No surface displacement, embankment settlement and video monitoring on the backwater side of the embankment;

[0180] Wherein, the construction method of the horizontal displacement and settlement deformation monitoring of the test section carried out by GPS, its steps are as follows:

[0181] (1) After selecting the points, excavate the monitoring pier foundation, and place the pier foundation in the bedrock (reference station) or in the undisturbed soil layer (monitoring station). The specific operation is: dig a foundation pit at the monitoring point, and the size of the foundation pit is length×width×height=1.5m×1.5m×1.5m. Then evenly anchor 8 φ12 steel bars into the...

Embodiment 3

[0192] In this embodiment, the monitoring equipment, construction method and dam safety monitoring system structure are the same as in Embodiment 1, the difference is that the dike section size and the installation position of the monitoring equipment are different, see image 3 with Figure 8 .

Abstract

The invention discloses a dam dangerous case emergency early warning system. The system comprises a front-end sensor acquisition layer; a data integration transmission layer; a data processing layer which comprises a dam safety monitoring intelligent management system and a database and is used for carrying out real-time data analysis processing and intelligent diagnosis on the monitoring parameters, judging whether various monitoring parameters reach an early warning threshold value or not and carrying out linkage early warning and / or expert diagnosis to form an emergency plan when the monitoring parameters reach the early warning threshold value; and a data publishing layer which is used for publishing the various monitoring results reaching the early warning threshold to a specified receiving terminal in an early warning information mode to be displayed. The dam dangerous section flood prevention emergency early warning system provided by the invention is high in early warning reliability, has excellent monitoring performance, has high-reliability analysis and early warning functions, is good in durability, and can play a role for a long time; the system is very suitable for damdangerous section flood prevention safety monitoring and early warning.

Description

technical field [0001] The invention relates to the technical field of monitoring and emergency early warning, in particular to an emergency early warning system for dam danger. Background technique [0002] At present, the internal hidden dangers of embankments and the single problem of detection, detection and monitoring technology are more prominent, which poses a greater threat to the safety of flood control and anti-alliance projects in the watershed. There are a large number of revetment projects such as wave walls, but traditional project management methods and monitoring technologies can no longer fully meet the needs of project safety management. There is almost no flood control safety network monitoring and early warning equipment and technology for a large number of embankment risk workers around the world. [0003] Therefore, it is necessary and urgent to carry out the construction of dam safety monitoring and early warning system combined with the advanced infor...
