Face rockfill dam seepage prevention structure
The invention provides a face rockfill dam seepage prevention structure. The face rockfill dam seepage prevention structure comprises a bed rock and a toe plate located on the bed rock. A seepage prevention layer flush with the toe plate is mounted on the downstream side of the toe plate, a rockfill material, a transition layer, a cushion material, a geomembrane and a face plate are sequentially mounted upwards from the seepage prevention layer, a construction face is mounted on the side face, facing the downstream part, of the toe plate, and the face plate, the geomembrane, the cushion material, the transition material, the rockfill material and the seepage prevention layer are in contact with the construction face. Compared with the related technology, the face rockfill dam seepage prevention structure combines advantages of a concrete face rockfill dam and a geomembrane face rockfill dam, the face plate, the geomembrane, a water stop copper sheet, the toe plate, the seepage prevention layer, a seepage prevention curtain and the bed rock form a whole seepage prevention system, whole stress performance is improved, and the dam water stop effect is ensured.
本发明提供一种面板堆石坝防渗结构。所述面板堆石坝防渗结构包括基岩和位于所述基岩上的趾板，所述趾板下游侧设有与所述趾板平齐的防渗层，自所述防渗层向上依次设置有堆石料、过渡层、垫层料、土工膜和面板，所述趾板朝向下游的侧面为施工面；所述面板、土工膜、垫层料、过渡料、堆石料和防渗层均与所述施工面接触。与相关技术相比，本发明所提供面板堆石坝防渗结构结合了混凝土面板堆石坝和土工膜面板堆石坝的优点，将面板、土工膜、止水铜片、趾板、防渗层、防渗帷幕与基岩形成一道整体的防渗体系，提高整体受力性能，保证大坝止水效果。
