三都水电站施工导流设计

Design of construction diversion for Sandu Hydropower Station

本文介绍三都水电站施工采用分期导流方式,通过不同缩窄河床断面的分段导流对比,以及综合技术、经济、施工工期等方面均衡考虑,确定施工导流方式.工程实施结果表明该导流方案的技术、经济可行性较高,实施后有效降低了施工成本和施工难度.

The stage diversion pattern for the construction of Sandu Hydropower Station is introduced.Through comparing the sectional diversion of different narrow riverbed section and considering comprehensively construction technology,economy and construction period,the diversion pattern of this project is determined.The results showed that the feasibility of this diversion scheme is good in technology and economy.After it was implemented,the construction cost and construction difficulty were reduced effectively.
