武汉市金融港应急排涝泵站工程设计

光谷金融港泵站为武汉市政府2016年灾后重建重点督办项目,主要服务于光谷金融港地区的排水防涝,设计通过模型计算确定泵站规模Q=40 m^3/s。该泵站位于武汉东湖高新区秀湖公园用地范围,占地面积约8 942 m^2,属于市政、景观绿化复合式用地,是武汉市新时代首座公园式排涝泵站,同时也是武汉市首座大流量低扬程的竖井式贯流泵站,水泵装置及进出水流道均通过模型试验及CFD数值优化,确保水泵总体运行效率高于72%,另外还对水泵机组设置了在线监测系统。设计从排水系统、工艺、绿色、生态、节能、智慧泵站等方面均充分体现了新时代下市政排涝设施的全要素设计、创新理念,同时该泵站形式在武汉市水环境、水安全方面具有推广意义。

Design of Emergency Drainage Pumping Station in Wuhan Financial Port

The Guanggu Financial Port Pumping Station was a key project of Wuhan Municipal Government for the post-disaster reconstruction in 2016. It mainly serves for drainage and waterlogging prevention in Guanggu Financial Port area. The scale of pumping station Q = 40 m^3/s was determined by model calculation. The pumping station located in Xiuhu Park of Wuhan Donghu High-tech Zone, covering an area of 8 942 m^2, which belongs to municipal, landscape and greening compound land. It was the first park-type drainage pumping station in Wuhan in the new era of municipal administration and landscape greening. It was also the first vertical shaft tubular pumping station with large flow and low head in Wuhan. The pumping device and the inlet and outlet channels were all optimized by the mold T-test and CFD numerical model to ensure that the overall operating efficiency of the pump was higher than 72%. In addition, an on-line monitoring system was set up for the pump unit. The design fully embodied the whole factor design and innovative idea of municipal drainage facilities in the new era from the aspects of drainage system, technology, green , ecology, energy saving, intelligent punlping station , etc. At the same time, the form of the pumping station had promotional significance in water environment and water safety of Wuhan.
