云南某供水工程长距离重力流输水管道设计

Design of long-distance gravity flow water pipeline for a water supply project in Yunnan Province

云南某供水工程项目设计供水规模为5.0万m3/d,水源与水厂距离较远、落差大,属于典型的长距离有压重力流输水管道,为充分利用水头、保障输水安全,工程从管道走向、管径、管材、安全措施等方面进行设计,采用大小管径结合使用以降低工程造价,确保工程运行安全、技术经济合理。

The designed water supply scale of a water supply project in Yunnan is 50,000 m3/d,the distance between the water source and the water plant is far and the drop is large,it's a typic al long-distance pressurized gravity flow water pipeline,in order to make full use of the water head and ensure the safety of water transmission,the project is designed from pipeline direction,pipe diameter,pipe and safety measures,combined use of large and small pipe diameters to reduce engineering costs,ensure project operation safety,technical and economic rationality.
