灯泡贯流机水电站施工导流设计探讨

Discussion on Construction Diversion Design of Hydropower Stations Equipped with Bulb Type Turbines

低水头河床式水电站普遍采用灯泡贯流机型.在总结湖南省灯泡贯流机水电站工程施工实践经验的基础上,论述了施工导流的主要特点,并结合工程实例对灯泡贯流机水电站工程施工导流设计中的施工导流标准、施工导流方案、围堰结构型式及施工期通航等几个主要问题进行了探讨.对同类工程有借鉴作用.

Bulb turbines have been widely adopted in the water retaining hydropower stations with low water head.On the basis of the design and construction experiences from the hydropower stations equipped with bulb type turbines in Hunan Province,this paper expounds main features of construction diversion.And also in combination with many actual project examples,this paper discusses the issues on the construction diversion design,such as standard for diversion flood,diversion scheme ,structure type of cofferdam and navigation during construction period,etc.This can provide certain reference for the construction diversion of other similar projects.
