现役大坝坡面混凝土面板修复施工技术研究

Research on construction technology of comprehensive repair of concrete slab on the water-inward slope of the existing dam

混凝土面板堆石坝是近年来国内水电站采用较多的一种坝型,但部分面板坝也出现了各种各样的病害,亟需对混凝土面板裂缝进行修复。基于混凝土面板综合修复施工过程中的难点问题,进行技术创新,形成了一套较为完善的现役大坝迎水坡面混凝土面板综合修复施工技术,并对该技术的工艺原理、技术特点进行了系统分析,阐明了该技术的工程适用性和工程应用价值。

Concrete face rockfill dam is a type of dam that has been used more frequently in domestic hydropower stations in recent years.However,for many years,some face rockfill dams have also appeared various diseases,and it is urgent to repair the cracks of the concrete faceplate.Based on the difficult problems in the construction of comprehensive restoration of concrete slabs,this article carried out technological innovation and formed a relatively complete set of construction technology for comprehensive restoration of concrete slabs on the water-facing slope of active dams,and carried out the technological principles and technical characteristics of the technology.System analysis clarifies the engineering applicability and engineering application value of the research technology.
