Water stop structure for vertical joint of concrete faced rockfill dam
The invention relates to the field of earth and rockfill dam construction, in particular to a vertical seam water stop structure of a concrete faced rockfill dam, which can be suitable for large dislocation between panels caused by large uneven deformation of a dam body and a dam foundation in a deep and thick covering layer geological condition or a strong earthquake area and can still keep a good water stop effect. Comprising two panels which are adjacently arranged in the vertical direction, in-seam filler is arranged in a seam between the two panels, an anti-seepage structure is arranged on the side, facing the water seepage direction, of the seam, the anti-seepage structure isolates the seam from the side, away from the water seepage direction, of the seam, and flexible asphalt mortar is arranged on the side, away from the water seepage direction, of the seam. The copper water stop piece is arranged in the flexible asphalt mortar, the two ends of the copper water stop piece are fixedly arranged in the panel respectively to form a water stop structure, the copper water stop piece comprises at least one U-shaped fold structure, and the fold direction of the copper water stop piece is consistent with the water pressure direction.
本发明涉及土石坝建筑领域，尤其是一种可以适应于深厚覆盖层地质条件或强地震区域，坝体及坝基较大的不均匀变形导致面板间产生较大错位，仍然可以保持良好止水效果的面板坝垂直缝止水结构，包括沿竖直方向相邻设置的两个面板，两个面板之间的缝隙内设置有缝内填料，所述缝隙朝向渗水方向一侧设置有防渗结构，防渗结构将所述缝隙与渗水方向一侧隔绝，所述缝隙远离渗水方向一侧设置有柔性沥青砂浆，包括铜止水片，所述铜止水片设置于柔性沥青砂浆内，所述铜止水片的两端分别固定设置于面板内进而形成止水结构，所述铜止水片包括至少一个U型褶皱结构，所述铜止水片褶皱方向与水压力方向一致。
