"倒口出流"消能工在洪江船闸输水系统中的应用

洪江二级船闸水头较大,输水消能问题较突出。通过模型试验对传统的长廊道多支孔的分散式输水系统与在中小水头集中式输水系统中成功运用的“倒口出流”消能工进行了方案比较,最终采用了“倒口出流”消能布置方案,这也是“倒口出流”消能工首次应用于分散输水系统。详细介绍了对模型试验的比选和洪江船闸的输水系统布置。

Application of "Flowing through the Inverse Opening" Energy Dissipator to Water Conveyance System of Ship-lock in Hongjiang Project

Energy dissipation in water conveyance system of the two_stage ship_lock of Hongjiang project is an outstanding problem due to the high water head. Dissipation schemes comparison is carried out through model test between conventional long gallery with multiple outlet and the "flowing through the inverse opening", which had been successfully applied to concentrated water conveyance system with mid or low water head. The scheme of "flowing through the inverse opening" is finally adopted by Hongjiang project, and this is also the first time that the "flowing through the inverse opening" energy dissipator is applied to the distributed water conveyance system. The details of comparison of model tests and the arrangement of the water conveyance system are presented in the paper.
