| 摘 要： | 根据南水北调总干渠总体设计技术规定:输水管道穿越总干渠,其穿越建筑物不占用总干渠水头.为满足总体设计要求,根据输水管道管底高程、总干渠渠底高程及设计水位的相互关系,考虑了渠上管道桥和渠底倒虹吸两种穿越方案,通过技术、经济、施工等综合分析比较,确定输水管道穿总干渠建筑物型式为渠底倒虹吸,倒虹吸管外加防护箱涵.

| Abstract: | According to the design technology standard of South-to-North Water Transfer Project main channel, the construction of water pipeline crossing the main channel will not occupy the water head of main channel. Based on the relationship among the bottom elevations of water pipeline and main channel, and the design water line, pipeline bridge upon the channel and the inverted siphon under the bottom of channel have been considered. After the comprehensive analysis and comparison on technology, economy, and construction etc, the inverted siphon under the bottom of channel with the protective box culvert outside has been used for the construction of water pipeline when crossing the main channel. |
