大型灌区自压输水管道水锤防护措施研究进展

Research Progress of Water Hammer Protection Measures in Large Irrigated Areas

跨流域调水工程可以解决水资源分布不均、地下水开采严重等当今社会面临的重大问题。地形条件符合的地区利用水的势能进行自压管道输水可以减少沿途水分蒸发、渗漏等问题。但在管道输水过程中水锤问题是值得研究的重大问题,是一直以来管道输水的安全隐患。本文结合国内外专家学者研究现状,对管网铺设管径选择,水锤防护措施以及组合技术,阀门启闭方式与历时,水锤防护中的软件应用作了研究分析,并对防护技术前景做了展望。

The inter-basin water transfer project can solve the uneven distribution of water resources and serious exploitation of groundwater etc.major problems that people are facing nowadays.Using potential energy of water to carry out self-pressure pipeline can reduce evaporation and leakage of water along the way.However,the water hammer problem is a major problem to be studied in pipeline transportation all the time.Combining the research status of domestic and foreign experts and scholars,this paper studied and analyzed the selection of pipe diameter,water hammer protection measures,the combination technology,the valve opening and closing and diachronic,and the application of software in water hammer protection and prospected the protection technologies in the future.
