天津干线是南水北调一期工程的重要组成部分,工程起点为南水北调中线总干渠西黑山分水口,终点为天津市外环河泵站。输水方式为全自流无压接有压输水,布置调节池实现由无压流向有压流的过渡和转换。就输水箱涵断面的选取、结构设计进行分析,供类似箱涵输水工程参考。
The Tianjin trunk line is an important part of the first phase of the South-to-North Water Diversion Project. The starting point of the project is the West Blackwater Channel of the main canal of the Middle Route of South-to-North Water Diversion, with the terminus being the Outer Ring River Pumping Station in Tianjin. Water way for the whole flow without pressure water pressure, the arrangement of the pool to achieve the pressure from the no-pressure flow transition and conversion. Analysis on the selection of water conveyance culvert section and structural design for reference of similar culvert water conveyance project.
