摘要
趾板是混凝土面板与基础之间的连接构件,其主要作用是防渗。以安徽响水涧抽水蓄能电站为例,介绍混凝土面板堆石坝的结构特点、截面参数、布置形式以及趾板与面板的连接。阐述趾板开挖、混凝土施工、锚杆施工、钢筋制作安装、模板制作安装等施工工艺。同时介绍采用板包法进行止水保护以及混凝土养护措施。
The toe slab with the function of anti-seepage is a connection member between concrete panel and foundation.Taking Xiangshuijian pumped storage power station in Anhui as example,structural characteristics,section parameters and layout of concrete panel rockfill dam are introduced as well as connection between toe slab and panel.Besides,construction technologies are outlined including excavation of toe slab,concrete construction,production and installation of steel bar and formwork.At the same time,sealing protection is done by adopting board package methods.The measures of concrete curing are discussed.
