Automatic safety monitoring system for earth and rockfill dam

Abstract

The invention relates to an automatic safety monitoring system for an earth and rockfill dam. The system comprises an acquisition device, a monitoring device, a communication unit and a monitoring center, wherein the acquisition device acquires dam safety data according to the set time period, the monitoring device monitors the surface displacement of the dam and integrates existing infiltration line monitoring equipment in the construction period of the dam, and the dam safety data acquired by the acquisition device are transmitted to the monitoring center through the communication unit. The automatic safety monitoring system for the earth and rockfill dam can be provided with multi-level clients such as provinces, cities, counties, reservoirs and the like, and the functions of automatic acquisition, storage, monitoring analysis, early warning and the like of data are planned to be achieved; and the system is mainly used for monitoring surface displacement influencing safety of medium and small earth and rockfill dams and monitoring infiltration lines, and an automatic safety monitoring facility for the dam is designed and installed or an existing automatic monitoring facility is accessed to a platform.

Description

technical field [0001] The invention relates to an earth-rock dam safety automatic monitoring system, belonging to the technical field of earth-rock dam safety monitoring. Background technique [0002] The main purpose of dam safety monitoring is to grasp and understand the actual engineering properties of the dam, and provide reliable information for judging the safety degree of the dam. Although the designers have adopted the safety factor when designing the dam, so that the dam can bear safely within the range of various load combinations within the scope of consideration, but because the designer cannot make any predictions about the bearing capacity and working conditions of the dam during the design It is impossible to fully guarantee the construction quality without making a completely correct estimate. Some relatively unpredictable changes may still occur during the working process of the dam. Therefore, there are still some engineering examples of dam failures at ho...

AI Technical Summary

Problems solved by technology

[0004] 1) The proportion of small reservoirs with safety monitoring facilities is less than 10%; all small reservoirs have not built safety monitoring facilities, and dam safety monitoring has not been carried out

[0005] 2) Most of the small reservoirs are managed by townships and villages without special management agencies and professional technicians. Even a small number of reservoirs and dams with safety monitoring facilities have not carried out safety monitoring as required, and the monitoring facilities have not played their due role. In addition, the monitoring facilities have been abandoned due to lack of maintenance for a long time, resulting in waste of investment
