摘要
引江济汉干渠为南水北调中线水源区工程之一,穿越江汉平原腹地,截断了大大小小河流和沟渠50多条,拾桥河是最大的一条。通过对输水条件、投资等因素的比较分析,确定采用建节制闸的方案。拾桥河输水枢纽是我国最大的平立交相结合的输水工程。通过对拾桥河枢纽工程3种布置方案的比较与研究,最后确定了包括上下游泄洪闸、倒虹吸、左岸道路、码头(驳岸)的方案。所确定的方案具有枢纽建筑少、运行管理方便、投资省等特点。
The main diversion canal from the Yangtze River to the Hanjiang River is one of the works in water sources area of the middle route project of South to North Water Diversion Project. The canal passes through the Jianghan Plain and crosses with more than 50 rivers and canals, among which the Shiqiao River is the largest one. Through comparative analysis on water convey- ance condition, investment etc. , the scheme of regulation sluice is adopted. The Shiqiao River Diversion Junction is the largest level - and - overpass one in China. Through comparison and research of 3 layout schemes, the scheme consisting of upstream regulation sluice, inverted siphon, road on left bank, wharf etc. is selected. The scheme has advantages of less structures, convenient operation and management, low investment, etc.
