超大型水垫塘反拱底板施工工艺探讨OA
Discussion on Construction Technology of Reverse Arch Baseplate in Super Large Cushion Pool
白鹤滩水电站水垫塘采用反拱底板,规模位居国内第一.底板的反拱结构增加了施工道路、施工机械布置难度,随着各块底板的位置、坡度、分块尺寸等变化,施工工艺随之发生变化,增加了底板施工难度.笔者根据现场施工的探索实践,经总结分析提炼得出适应水垫塘反拱底板不同位置的拉模、盖模、翻模等不同组合的标准化施工工艺及管控要点,解决了施工难题,为类似工程施工提供参考.
The cushion pool of Baihetan Hydropower Station adopts reverse arch baseplate,ranking first in Chi-na in terms of scale.The reverse arch structure of the baseplate increases the difficulty of construction roads and construction machinery layout.As the position,the slope,block size,etc.of each baseplate change,resul-ting in changes in construction techniques and increasing the difficulty of baseplate construction.Based on the exploration and practice of on-si…查看全部>>
