The invention relates to an integral cofferdam plugging structure and a construction process. The device comprises two rows of steel sheet piles which are arranged in a riverbed surface and spaced by a preset distance, each row of steel sheet piles are broken so that obstacles below the riverbed surface can pass through, corrugated structures are longitudinally distributed along the steel sheet piles, the corrugated structures comprise vertical notches distributed along the inner and outer side faces of the steel sheet piles, and vertical grooves are formed in the respective broken positions of the two rows of steel sheet piles; the plugging device is arranged in the vertical groove and comprises longitudinal beams, cross beams, stand columns, stiffening beams, panels and steel pull rods, the longitudinal beams, the cross beams, the stand columns and the stiffening beams are mutually connected to form a steel structure frame, the panels are connected to the two transverse sides of the steel structure frame and are steel plates, the steel pull rods penetrate through the stiffening beams and are connected with the two panels, and limiting blocks are arranged on the outer side faces of the panels; the limiting blocks are arranged in vertical notches in the inner side faces of the steel sheet piles in a sliding fit mode, and the lower portions of the plugging devices are attached to the riverbed surface. The problem that the steel sheet pile cofferdam cannot be communicated due to the fact that obstacles exist under the riverbed is solved.
本发明涉及一种整体式围堰封堵结构及施工工艺。本发明包括设置在河床面中的两排间距预设距离的钢板桩，每排钢板桩具有断开以使河床面下方的障碍物通过，沿钢板桩纵向分布有波纹结构，波纹结构包括沿钢板桩内外侧面分布的竖向槽口，两排钢板桩各自的断开处形成竖向凹槽；设置于竖向凹槽内的封堵装置，包括纵梁、横梁、立柱、加劲梁、面板、钢拉杆，纵梁、横梁、立柱和加劲梁相互连接并形成钢结构框架，钢结构框架横向两侧连接有面板，面板为钢板，钢拉杆穿过加劲梁并连接两块面板，面板外侧面设有限位块；其中，限位块滑配于钢板桩内侧面的竖向槽口内，封堵装置下部与河床面贴合。本发明解决了河床下存在障碍物、钢板桩围堰无法贯通的问题。
