Anti-seepage joint structure of geomembrane anti-seepage panel and concrete anti-seepage wall and construction method
The invention discloses an anti-seepage joint structure of a geomembrane anti-seepage panel and a concrete anti-seepage wall and a construction method. The anti-seepage joint structure comprises the concrete anti-seepage wall, wherein a mold increasing area and a cushion layer which have a certain inclination angle are sequentially arranged on the side, close to a reservoir slope, of the concreteanti-seepage wall, a supporting layer which is bent and extends upwards is arranged above the mold increasing area and the cushion layer, and the end, close to the concrete anti-seepage wall, of the supporting layer is sunken downwards to form a groove; the geomembrane anti-seepage panel is laid on the surface of the supporting layer, and the bottom end of the geomembrane anti-seepage panel is fixedly connected with the concrete anti-seepage wall; and the area, corresponding to the groove, above the geomembrane anti-seepage panel is densely filled with fine filler, and the surface of the finefiller is covered with a reinforcing geomembrane. According to the geomembrane and foundation concrete anti-seepage wall connecting joint structure which is convenient and fast to construct, safe andreliable, a closed whole is formed for seepage prevention of a reservoir (dam), and the seepage loss is reduced.
本发明公开了一种土工膜防渗面板与混凝土防渗墙的防渗接头结构及施工方法，包括混凝土防渗墙，所述混凝土防渗墙靠近库坡一侧依次设置具有一定倾斜角度的增模区与垫层，所述增模区与垫层的上方设置有向上弯折延伸的支持层，且所述支持层靠近混凝土防渗墙的一端向下凹陷形成凹槽；所述支持层表面铺设土工膜防渗面板，且土工膜防渗面板的底端与混凝土防渗墙固定连接；所述土工膜防渗面板的上方与凹槽对应的区域内密实填充粉细填料，且所述粉细填料的表面覆盖有加强土工膜。本发明提出一种施工便捷、安全可靠的土工膜与基础混凝土防渗墙连接接头结构，确保库(坝)防渗形成封闭整体，减少渗漏损失。
