水磨沟倒虹吸管工程设计

Design of the siphon pipeline crossing Shuimogou Valley

水磨沟倒虹吸管是甘肃省引大入秦灌溉工程总干渠上的大型跨沟建筑物 ,为双管桥式倒虹吸 ,最大工作水头 6 8m ,管线总长 2× 5 6 8m ,输水钢管内径 2 6 5m ,加大输水流量 36m3/s。具有工作水头高、输水流量大、管线长、管径大的特性 ,其综合工程规模位居国内前列 ,通过运行实践证明 ,工程设计完善 ,运行可靠。

The siphon pipe-line,named Shuimogou,is the largest structure on the main canal of the Yinda-ruqin irrigation project.Characters of which,as following:structural style-double pipes on bridge,designed water pressure-68 m,total lenth-2×568 m,inside diameter of the pipes-265 m,designed discharge-36 m\+3/s.So far as above,the worths to be designed,at end,the operational practice shows that,the designed scheme is successful and safely.
