凉口灌区东干渠与宝溪河交叉处倒虹吸设计

Inverted Siphon Design for Intersections of Baoxi River and East Main Canal in Liangkou Irrigation district Project

针对东干渠与宝溪河交叉处共用渠道(河道)的特殊情况,分别考虑采用倒虹吸及涵洞两种处理方案进行分析比较,最终采用倒虹吸设计方案;通过对倒虹吸过流能力、进口沉沙池、出口消力池、镇墩结构计算等关键问题的分析计算,确定了设计技术参数,可为其他类似工程设计提供参考。

Aiming at the specific situation of East Main Canal and Baoxi River at the intersection of shared channel （River） , considering that analysis comparison is carried on between two kinds of inverted siphon and culvert treatment scheme, finally, inverted siphon design scheme has been chosen; With all the analysis and calculation of the flow capacity of inverted siphon, the import of desilting basin, the export of stilling pool, the structure of presses down mound, design technology parameters have been determined, which can be provided as references for other similar engineering design.
