重力管道输水方式因其对地质条件要求不高,渗漏损失小,施工方便,造价较低,管理方便等优点常作为设计者优先考虑的方案,然而大型区域的长距离重力流输水系统的管路安全问题成了供水工程安全运行的难题。文章选择以长距离重力流输水系统水锤防护作为研究方向,主要通过禹门口提水东扩工程重力流段第三区段水锤计算机数值模拟为例,探讨长距离重力流输水系统的水锤防护问题。
Due to its low requirements on geological conditions, small leakage loss, convenient construction, low cost and convenient management, gravity pipe water delivery is often considered as a priority for designers. However, large-scale long-distance gravity water conveyance systems Of the pipeline safety has become a problem of safe operation of water supply projects. This paper chooses long-distance gravity water conveyance system water hammer protection as the research direction, mainly through the numerical simulation of water hammer in the third section of gravity flow section of Yumenkou water diversion eastward expansion project as an example to discuss the long-distance gravity flow water delivery system Water hammer protection problem.
