梨园水电站面板混凝土配合比及浇筑关键技术问题探讨
|
摘要
通过对梨园水电站面板混凝土配合比及浇筑方案技术问题研究,重点对原材料比选、施工现场混凝土浇筑生产性试验等成功经验进行总结,提出了适合高海拔气候环境、大高差不利施工因素的最佳施工配合比和长溜槽施工方案。
Through the study on technology of mix ratio and placement scheme of the surface slab concrete of Liyuan Hydropower Station,the successful experience on selection of raw materials and the productive tests of the concrete placement are summarized especially. The optimum mix ratio and the construction scheme with long chute which are applicable to unfavorable factors such as the high-elevation environment and the large height difference are provided.
