Earth rock cofferdam and concrete cofferdam connecting structure and construction method thereof
The invention discloses an earth rock cofferdam and concrete cofferdam connecting structure and a construction method thereof.The earth rock cofferdam and concrete cofferdam connecting structure comprises an earth rock cofferdam and a concrete cofferdam, a first geomembrane is laid in the longitudinal section of the earth rock cofferdam, a series of anchor rods are arranged on the earth rock cofferdam contact face of the concrete cofferdam in the height direction, and all the anchor rods are horizontally arranged; a pre-embedded steel plate is installed on the anchor rod, a second geomembrane and a tabletting steel plate are sequentially laid on the pre-embedded steel plate, and the pre-embedded steel plate and the tabletting steel plate are connected into a whole through a fastener; the first geomembrane extends to the embedded steel plate and is seamlessly connected with one side of the second geomembrane, and the other side of the second geomembrane is seamlessly connected with the concrete cofferdam; concrete is poured between the earth rock cofferdam and the concrete cofferdam to form a geomembrane connecting wall, and the concrete covers the anchor rods, the embedded steel plates, the first geomembrane and the tabletting steel plates. The integrality of the earth rock cofferdam and the concrete cofferdam is enhanced, the method can be suitable for high water head seepage prevention, and compared with a traditional method, the method has more advantages in construction quality and construction speed.
本发明公开了一种土石围堰与混凝土围堰连接结构及其施工方法，包括土石围堰和混凝土围堰，土石围堰的纵断面内铺设第一土工膜，混凝土围堰的土石围堰接触面上沿高度方向布设一系列锚杆，且各锚杆水平设置；锚杆上安装预埋钢板，预埋钢板上依次铺设第二土工膜和压片钢板，预埋钢板和压片钢板用紧固件连接成一体；第一土工膜延伸至预埋钢板，并与第二土工膜的一侧无缝连接，第二土工膜的另一侧与混凝土围堰无缝连接；土石围堰和混凝土围堰之间浇筑混凝土形成土工膜连接墙，混凝土覆盖锚杆、预埋钢板、第一土工膜及压片钢板。本发明增强了土石围堰与混凝土围堰的整体性，可适用于高水头防渗，在施工质量与施工速度上相较于传统方法更具优势。
