赤壁市长江取水工程取水设计

Engineering Design of Water Intake Project for Yangtze River Water Intake Project in Chibi City

针对该项目需要从长江长期取到合格原水,且需要保证取水泵房结构稳定、施工方案成熟经济的工程目标,文章调研了湖北境内江河取水工程的设计,在满足功能需求的基础上,对结构形式、施工便利性及经济性作多方比选,最终确定在赤壁山矶头上游1.20 km处设置固定式取水头部、采用自流式引水钢管、圆形沉井取水泵房内设离心泵的建设方案。工程方案科学合理、结构稳定、施工周期短、取水稳定,可为类似取水工程的设计提供参考。

In view of obtaining qualified raw water from the Yangtze River for long time,and ensuring the target of stable structure of water intake pump house,mature and economical construction plan,the design of water intake projects in Hubei province is investigated.On the basis of meeting functional needs,the structural form,construction convenience and economy are compared,and the construction scheme of fixed water intake head at 1.20 km upstream of Jitou in Chibi Mountain,self-flow water diversion rigid pipe and centrifugal pump in circular caisson water intake pump house is determined finally.The project scheme has advantages of scientific and reasonable,structure stabilization,short construction period and stable water intake,which can provide reference for the design of similar water intake projects.
