大口径引输水管道漏损监测技术研究进展

Research Progress on Leakage Monitoring Technology for Large-Diameter Water Transmission Pipelines

大口径引输水管道作为城市公用建设基础设施,承担着向各个用水节点供水的重任,具有距离长、口径大、输水量大、运行压力高等特点。引输水管道系统在运行过程中,因老化、第三方施工、内外荷载、自然或人为因素等造成的输配水管道泄漏、破裂、爆裂等管道损坏事件逐年增加。一方面造成供水资源的浪费,另一方面增加运行成本和影响服务质量。通过采取先进的漏损监测技术和管理手段,及时发现和定位泄漏位置,合理控制和降低管道漏损,可有效提高供水能力,保障供水安全。文章通过全面分析管道系统漏损原因,梳理漏损监测方法,分析不同监测方法的适用性,提出管道漏损监测技术的建议和方法。对于大口径引输水管道漏损监测技术的研究与应用具有一定的指导意义。

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 diferent 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.
