Ⅰ. 给水管网课程设计任务书

一、 设计项目

某市给水管网课程设计

二、 设计任务

根据所给资料，应完成下列任务：

1、进行输配水系统布置，包括确定输水管、干管网、调节水池（如果设置的话）的位置和管网主要附件布置；

2、求管网、输水管、二级泵站的设计用水量与调节水池的容积； 3、计算确定输水管和管网各管段管径； 4、进行管网水力计算；

5、确定二级泵站的设计扬程，如果有水塔，确定水塔的设计高度； 6、确定二级泵站内水泵的型号与台数（包括备用泵）,并说明泵站在各种用水情况下的调度情况；

7、画出管网内4～6个节点详图。

三、 设计资料

1、某市规划平面图一张。 2、某市规划资料。

某市位于湖南的东部，濒临湘江。近期规划年限为6年，人口数为12万，城区大部分房屋建筑控制在6层。全市内只有两家用水量较大的工业企业，其用水量及其他情况详见表1。

表1 工业企业近期规划资料

企业 项目 1.企业用水量（米/日） 工业用水对水质要求 工业用水对水要求 2.工厂房屋耐火等级 工程生产品危险等级 31 2 2400 同生活饮用水 不小于24米 二 丙 3600 同生活饮用水 不小于24米 三 乙 - 3 -
