北部引嫩渠首泄洪闸工程是渠首枢纽工程的重要组成部分,位于嫩江主河道上,是千亿斤粮食重点工程,工程量巨大,施工难度大。导流工程的设计与施工直接决定主体工程能否按期完工,能否安全度汛。在此着重对该工程导流明渠设计及施工进行论述,为寒冷地区大江大河上修筑枢纽工程导流设计施工提供经验。
The northern part of Nenjiang drainage project is the flood control sluice project is an important component of the project, located in the main river Nenjiang, is 100000000 jin key grain project, a huge amount of construction difficulty. The design and construction of the diversion project directly determine whether the main project can be completed on schedule and whether the flood season can be safe. In this emphasis, the design and construction of the diversion channel of the project will be discussed, providing experience for the construction of diversion design and construction of the hub project in major rivers in cold regions.
