新疆大型倒虹吸管道工程的运行调度计算及充排水方案复核

Operation Scheduling & Review of Water Filling and Drainage Scheme with Large Inverted Siphon Pipeline Project in Xinjiang

采用相关水力学公式分别计算了倒虹吸玻璃钢管道的运行调度、充排水时管内水力特性、出口闸门关闭时管道内水击压力值等。计算结果表明,出口闸门全开至全关时间以大于350 s为宜。复核计算倒虹吸管道放空阶段,沿程布设的进排气孔数量及孔径均满足需求。

This paper uses the hydraulic formula to calculate the operation scheduling, the hydrau- lic characteristics of pipeline during the filling and drainage , the water hammer pressure of pipeline when the exit gate is closed etc. The hydraulic calculation shows that the exit gate fully open to fully closed in time should be more than 350s. Checking calculation of inverted siphon pipeline stages a- long the layout of the intake and exhaust hole number and diameter shall meet the requirements.
