龙潭水库至1号隧洞管线水力过渡过程分析
|
摘要
龙潭水库至1号隧洞进口段为该工程的首部枢纽供水管段,与主输水管线连接,也是1号有压输水管线与2号无压输水主管线的结合点。其间,1号主管线段有石嘴子截引点、红家峡截引点有压力流汇入。为节省工程投资和减少水力损失,1号主引水管线采用PCCP管与玻璃钢管组合的管线型式,如何进行管线的压力控制,如何进行截引点汇入流量的控制,及如何控制1号有压管线的流量使之流入2号无压管线时安全,是需要进行水力研究采取措施的重要技术问题之一。
The section from Longtan Reservoir to No. 1 tunnel inlet is regarded as the head hub water supply pipe section of the project. It is connected with the main water pipeline,which also acts as the junction of No. 1 pressure watertransmission pipeline and No. 2 unconfined main water pipeline. Wherein,pressure flow converges into Shizuizi interception point and Hongjiaxia intersection point of No. 1 main pipeline. PCCP pipe and glass steel pipe are combined as No. 1 main water diversion pipeline in order to save engineering investment and reduce hydraulic loss. How to control the interception point convergence flow capacity,how to control the flow capacity of No. 1 pressure water-transmission pipeline and make it safe when water flows into No. 2 unconfined main water pipeline. It is one of important technical problems that hydraulic research is required and measures should be adopted.
