Description

Technical Field

[0001] This invention relates to the field of leakage tracing technology, and in particular to a method and system for tracing and identifying leakage sources in water diversion projects. Background Art

[0002] The field of leak source tracing technology focuses on detecting and identifying seepage problems in hydraulic engineering projects to ensure structural safety and functionality. It utilizes various methods such as physical detection, chemical tracing, and computer simulation to determine the source and path of water flow. This helps engineers and maintenance personnel locate leak points and implement effective remediation measures. The application of leak source tracing technology is crucial, especially in large dams, reservoirs, pipelines, and hydraulic facilities, where leaks, if not addressed promptly, can lead to serious structural damage and environmental problems.

[0003] Among them, the water diversion project leakage source identification method refers to a technical means specifically used for the detection and source tracing of seepage points in water diversion projects. By integrating advanced sensor data, geographic information systems, and machine learning techniques, it effectively tracks and locates abnormal leakage paths of water flow. Its main purpose is to prevent and repair leakage problems, ensure the effective management and allocation of water resources, reduce water waste, and protect the long-term stability of hydraulic structures.

[0004] Existing leak tracing technologies rely on physical detection or chemical tracing. While effective in some cases, these methods require considerable time to identify and locate leaks, and their accuracy and efficiency are limited in large-scale or complex hydraulic systems. For example, physical detection techniques such as acoustic monitoring are significantly affected by topography and materials, while chemical tracing is influenced by environmental factors, impacting the accuracy and reliability of the results. Traditional technologies struggle to achieve real-time monitoring and analysis of water flow dynamics, resulting in insufficient response time to rapidly changing seepage events and a failure to intervene effectively before the problem reaches a critical stage. This delay leads to unnecessary resource waste and potential safety risks, especially in emergencies where the lack of rapid and accurate data makes it difficult to implement effective emergency measures.
