Research Progress on Leakage Monitoring Technology for Large-Diameter Water Transmission Pipelines
Large-diameter water transmission mains,as a critical urban infrastructure,is responsible for delivering water to various water users.The system features long distance,large diameter,large water transmission capacity,and high operating pressure.During the operation of the water supply pipeline system,incidents of pipeline damage such as leakage,rupture,and burst caused by aging,third-party damage,internal and external loads,natural or human factors have been increasing over the years.On one hand,it wastes water resources,and on the other hand,it increases operating costs and affects customer service quality.By implementing advanced leakage monitoring and control technologies,it can identify and locate leaks in time which helps reasonable control and reduces leakage and greatly improves the resilience of water supply.This paper comprehensively analyzes the causes of leakage in pipeline system,sorts out the methods of leakage monitoring,analyzes the applicability of different monitoring methods,and puts forward the suggestions and methods of pipeline leakage monitoring technology.It has certain guiding significance for the research and application of leakage monitoring technology of large diameter water diversion pipeline.
