叶巴滩水电站大坝跨江照明系统施工技术

Construction Technology of Cross-River Lighting System in Yebatan HEP

水电工程的大坝混凝土施工夜以继日,其夜间施工的照明及安全的重要性可想而知。阐述了叶巴滩水电站大坝施工时充分利用山区地形特点设置跨江照明系统,既满足了施工照明的需要,亦可起到高空安全警示的作用,使其成为工地一道亮丽的景观。近年来跨江照明系统在水电工程建设中开始逐步尝试使用,但其在高原高海拔恶劣气候环境地区使用尚属国内首次。鉴于今后的水电工程建设逐步向高山峡谷地区转移,叶巴滩水电站大坝跨江照明系统的成功应用即可为今后高原跨江照明系统的设计与施工提供经验。

Given the concrete placement of dam is carried out day and night in hydropower project,the lighting system is of great importance.This paper elaborates the design of the cross-river lighting system in Yebatan hydropower project by full use of the terrain characteristics of the mountain area,which not only meets the needs of construction lighting,but also plays the role of high-altitude safety warning,making it a beautiful landscape on the construction site.In recent years,the river crossing lighting system has been gradually used in hydropower projects,but it was the first time in China that used in the plateau high-altitude harsh climate environment.Since more and more hydropower projects will be built in alpine and canyon areas in the future,the success application of the cross-river lighting system in Yebatan HEP can provide reference for the design and construction of the cross-river lighting system on the plateau in the future.
