城市应急水源工程创新设计思路与实践

Innovative Design Ideas and Practice of Urban Emergency Water Source Project

针对应急水源工程使用频率极低的特征,为降低工程实施难度与投资,对应急取水泵房和应急原水管道进行了创新设计。采用柴油发动机代替传统电机驱动水泵,可节省双回路10kV电源工程量,且每年无需缴纳高昂的基本电费。优化应急原水管道的功能定位,通过增加安全可靠的切换措施,使其具备输送原水和清水的双重功能,节省道路下方有限的管位资源,发挥工程投资效益。以安徽某市应急水源工程为例,在降低取水泵站供电外线实施难度和初期投资的同时,每年还可节省680万基本电费,此外,将应急原水管道平时当清水管道使用,解决了现状道路无法同时实施两根大口径管道的矛盾。

In view of the characteristics of extremely low use frequency of emergency water source project,innovative design of e-mergency water intake pump house and emergency raw water pipeline was carried out to reduce the difficulty of project implementa-tion and investment.By using diesel engine instead of traditional motor to drive water pump,not only 10 kV power supply of double circuit could be saved,the high basic electricity bill could also be saved every year.Function positioning of emergency raw water pipeline was optimized.By adding safe and reliable switching measures,the pipeline has the dual function of conveying raw water and clean water,which could save the limited resources under the road and give play to the investment returns.Take an emergency water source project in a city of Anhui as an example,the innovative design could not only reduce the difficulty and initial investment of the outside line of power supply in the pumping station,but also saved 6.8 million in basic electricity bills each year.In addition,the emergency raw water pipeline was used as a clean water pipeline at ordinary times,which solve the contradiction that two large-cal-iber pipelines cannot be implemented on the road at the same time.
