Water stop structure for peripheral joint of concrete faced rockfill dam

The invention relates to the field of earth and rockfill dam construction, in particular to a concrete faced rockfill dam peripheral seam water stop structure which can be adapted to deep and thick covering layer geological conditions or strong earthquake areas, can still keep a good water stop effect when large dislocation is generated between a panel and a toe board due to large uneven deformation of a dam body and a dam foundation. A toe board and inter-panel filler are arranged in a gap between the panel and the toe board, an anti-seepage structure is arranged on the side, facing the water seepage direction, of the gap and isolates the gap from the side, facing the water seepage direction, of the gap, and panel bottom filler is arranged on the side, away from the water seepage direction, of the gap. The panel bottom filler is arranged in a cavity formed by the toe board, the panel inter-panel filler, the panel, the toe board and the asphalt mortar cushion layer, the copper water stop strip is arranged in
