Mold bag concrete longitudinal cofferdam structure
The invention relates to a mold bag concrete longitudinal cofferdam structure and a construction method, and belongs to the field of water conservancy and hydropower engineering. The mold bag concrete longitudinal cofferdam structure comprises a concrete platform located on the shore side, cantilever beams are pre-buried in the concrete platform, the cantilever beams are provided with overhanging sections extending towards the interior of a river channel relative to the concrete platform, the multiple cantilever beams are arranged in the length direction of the river channel at intervals, and the overhanging sections of the cantilever beams are fixedly connected with a fixing frame; the lower end of the fixing frame is inserted into the river bottom, mold bag concrete is arranged in the fixing frame and arranged in the length direction of the river channel, and backfill concrete is arranged in the area between the mold bag concrete and the concrete platform. The concrete platform, the cantilever beam and the steel frame are combined into an organic whole, the steel frame serves as a rigid support of mold bag concrete, the reliability of the whole structure is fully guaranteed, and water flow can be effectively blocked in a river channel with the large depth and the large flow speed.
本发明涉及一种模袋混凝土纵向围堰结构及施工方法，属于水利水电工程领域。本发明中的模袋混凝土纵向围堰结构，包括位于岸边的混凝土平台，混凝土平台内预埋有悬臂梁，悬臂梁相对于混凝土平台具有朝向河道内伸出的悬伸段，悬臂梁沿着河道长度方向间隔布置多根，悬臂梁的悬伸段固定连接有固定框架，固定框架的下端插入河底，固定框架的内部设置有模袋混凝土，模袋混凝土沿着河道长度方向设置，模袋混凝土与混凝土平台之间的区域设置有回填混凝土。混凝土平台、悬臂梁、钢框架组合成一个有机整体，由钢框架作为模袋混凝土的刚性支撑，充分保证整体结构的可靠性，在深度、流速均较大的河道中能够有效拦挡水流。
