Anti-seepage and slope-fixing integrated dam asphalt concrete panel structure and construction method
The invention discloses a seepage-proofing and slope-fixing integrated dam asphalt concrete panel structure and a construction method, the seepage-proofing and slope-fixing integrated dam asphalt concrete panel structure comprises a plurality of layers of leveling cement walls, the leveling cement walls are trapezoids with narrow upper bottoms and wide lower bottoms, and the lower bottoms of the leveling cement walls are stacked on the upper bottoms of the leveling cement walls below to form a multi-layer stepped structure; the upstream faces of the multiple layers of leveling cement walls are all located on the same inclined face to form a flat slope face, an asphalt concrete impermeable layer and an asphalt mastic sealing layer are sequentially laid on the slope face, and dam body filling materials are arranged behind the leveling cement walls. Seepage prevention and slope fixation are integrated, the slope protection function of a dam is achieved, meanwhile, the functions of leveling a traditional leveling cement layer foundation and ensuring stability and integrity of an upper layer structure are considered and improved, horizontal plane construction of a leveling cement wall is achieved, the asphalt panel structure is improved, meanwhile, the construction procedure can be simplified, the construction period is shortened, and the construction efficiency is improved. The problems of potential safety hazards, slow progress and the like of a leveling cementation layer slope paving and rolling process are solved.
本发明公开了一种防渗固坡一体的大坝沥青混凝土面板结构及施工方法，包括若干层整平胶结墙，整平胶结墙为上底窄，下底宽的梯形，若干层整平胶结墙的下底垒在下方整平胶结墙的上底之上，形成多层阶梯结构，若干层整平胶结墙的迎水面均处在同一斜面上，形成平整斜坡面，斜坡面上依次铺设沥青混凝土防渗层和沥青玛蹄脂封闭层，整平胶结墙后方为坝体填筑料。本发明将防渗与固坡一体化，既满足了大坝的护坡功能，同时又兼顾并提高了传统整平胶结层基础整平、确保上层结构稳定和整体性的功能，实现整平胶结墙的水平面施工，在沥青面板结构改进的同时又能简化施工工序，节约工期，解决整平胶结层斜坡摊铺及碾压工艺潜在的安全隐患、进度缓慢等问题。
