Reverse drainage quick plugging structure and ballasting-free plugging method
The invention relates to a reverse drainage quick plugging structure and a ballasting-free plugging method.The reverse drainage quick plugging structure is used for plugging a reverse drainage pipe of a concrete faced rockfill dam, the concrete faced rockfill dam comprises a toe board and a panel, and the reverse drainage pipe is arranged on the side, close to the panel, of the toe board. The reverse drainage quick plugging structure comprises an SR extrusion bag, preshrinking mortar and a plugging cover plate, the SR extrusion bag is arranged at the bottom of the reverse drainage pipe, the preshrinking mortar is arranged in the reverse drainage pipe and extends to an orifice of the reverse drainage pipe from one side of the SR extrusion bag, the plugging cover plate covers the orifice of the reverse drainage pipe, and the SR extrusion bag is arranged at the bottom of the reverse drainage pipe. And the plugging cover plate is fixedly connected with the toe board. According to the reverse drainage quick plugging structure, the reverse drainage plugging time can be shortened, the lifting amplitude of the water level of the dam body in the plugging period is reduced, and meanwhile the reverse water pressure jacking problem in the plugged dam body is solved through the measures of soil filling in the foundation pit, auxiliary saddle weights and water body pressing covering after water filling.
本申请涉及一种反向排水快速封堵结构及无压重封堵方法，其中，反向排水快速封堵结构用于对面板堆石坝的反向排水管进行封堵，面板堆石坝包括趾板和面板，反向排水管设置于趾板靠近面板的一侧。该反向排水快速封堵结构包括SR挤压包、预缩砂浆和封堵盖板，SR挤压包设置于反向排水管的底部位置，预缩砂浆设置于反向排水管内，且预缩砂浆由SR挤压包的一侧延伸至反向排水管的孔口，封堵盖板覆盖于反向排水管的孔口位置，且封堵盖板与趾板固定连接。该反向排水快速封堵结构能够减少反向排水封堵的时间，降低封堵期间的坝体水位的抬升幅度，同时利用基坑内填土、辅助压重块和灌水后水体压覆的措施解决封堵后坝体内的反向水压顶托问题。
