摘要
近年来,随着水源地保护力度不断加大,出现了一些需要搬迁的取水口。为保证取水口迁建后取水能力不变,需以现状系统的最低取水水位、水头损失和起泵吸水井最大水位降落差作为设计的约束条件,通过优化取水管线路,扩大取水管管径等方式,对冲由于迁建导致的取水距离增加。以某100万m^3/d取水口迁建工程为例,介绍了相关的设计步骤和内容。
In recent years,with the increasing protection of water sources,there have been some water intakes that need to be relocated.In order to ensure that the capacity of the water intake is unchanged after the relocation,it is necessary to use the minimum water level,head loss and maximum water level drop of the pumping well as the design constraints,by optimizing the water intake line,expanding the way of taking water pipes,etc,solve the increase in water intake distance due to relocation.This paper takes a one million m3/d water intake relocation project as an example and introduces the relevant design steps and contents.
