在农村自来水建设中,如何合理设计和布局管网是一项很重要的工作。几年来,我们经过多次实践与探索,对我区大中型改水工程采用了管网分级设计的方法,取得了较理想的效果。1 管网分级设计的概念 何谓管网分级设计:即在水厂总供水量和供水规模不变的情况下,在设计管网时,根据其分段管网的供水量和供水规模,取用不同的日供水时间和K时值,以达到最佳设计与供水。
In the construction of rural tap water, how to design and layout the pipe network is a very important task. Over the past few years, after many practices and explorations, we adopted a method of hierarchical design of pipe network for large and medium-sized water diversion projects in our region and achieved satisfactory results. 1 The concept of pipe network grading design What is the pipe network grading design: In the case of the total water supply and water supply in the waterworks, the design of pipe network, according to its sub-pipe network of water supply and water supply scale, access Different days of water supply and K value, in order to achieve the best design and water supply.
