Ⅲ、Ⅳ类学生宿舍给水管网设计探讨

Probe into plumbing system design for the Ⅲ、Ⅳ student dormitories

在市政管网供水充足的条件下,针对某大学已建工程存在供水压力及水量不足的问题进行改造,重点分析Ⅲ、Ⅳ类学生宿舍集中用水时,设计秒流量确定应考虑的因素,给水管网布置对上层宿舍水压的影响以及室内干管的水头损失情况,论证了合理分配给水引入管服务卫生器具数量、室内给水管网布置成环状是保证Ⅲ、Ⅳ类学生宿舍上层水压的重要措施。

Under the condition of supplement water quantity supply from the municipal water supply network, a reconstruction project was completed in a university to solve the problems of not enough water pressure and water quantity in built buildings. Taking this project as an example, this paper analyzed the considering factors about the design flow for the peak water consumption of the Ⅲ、Ⅳ student dormitories and the effects on high-level dormitories water pressure and indoor water pipe head loss. It was concluded that the proper distribution of sanitary appliances quantity on inlet pipe and the indoor looped network were the important measures for the security of the wa- ter pressure for the high-level Ⅲ、Ⅳ student dormitories.
