水库砼面板堆石坝趾板施工技术

Construction Technology of Concrete Face Rockfill Dam Toe

趾板是连接地基防渗体与面板的砼板,布置在防渗面板的周边,坐落在河床及两岸基岩上的混凝土结构。趾板施工程序繁多,施工工艺复杂,技术要求高,是大坝施工中重点部分。本文结合某水库具体特点,对趾板施工工艺进行探讨。

Toe board is the concrete board connecting the foundation anti-seepage body and the face plate,which is arranged in the periphery of the anti-seepage face plate,and is located in the riverbed and the bedrock on both sides of the concrete structure.Toe plate is a key part of dam construction due to its various construction procedures,com⁃plex construction techniques and high technical requirements.Based on the specific characteristics of a reservoir,this paper discussed the construction technology of toe plate.
