Peripheral seam stagnant water structure of superelevation concrete face rockfill dam

The utility model belongs to the hydraulic and hydroelectric engineering field specifically discloses one kind and has adapted to the stronger peripheral seam stagnant water structure of superelevation concrete face rockfill dam of seam deformability. This peripheral seam stagnant water structure of superelevation concrete face rockfill dam includes the peripheral seam that is in between concretepanel and the dam toe board to and top stagnant water, middle part stagnant water and bottom stagnant water, peripheral seam is including the seam top and seam middle section and the seam bottom thatare the V font, top stagnant water, middle part stagnant water and bottom stagnant water set up respectively and are stitching top, seam middle section and seam bottom. This periphery seam stagnant water structural formation has multilayer seepage prevention system, makes it have good impermeability ability, and what the adaptation seam was out of shape can the reinforce to the construction is simple and convenient, can no
