Water flow impact force self-expanding type river breach plugging method
The invention discloses a water flow impact force self-expansion type river channel breach plugging method which is characterized in that a plugging pipeline which can be pulled and is of a multi-section sleeve type pipeline structure is put into a river channel along the water flow direction on an embankment at the upstream end of a breach, and the upper end of the plugging pipeline is fixedly connected to the upstream end of the breach; the plugging pipeline is impacted by river water in a river channel so that the sleeves can be automatically unfolded, the tail sleeve exceeds the breach position, reaches the downstream end of the breach and can be limited to the inner side walls of the embankment at the two ends of the breach due to impact of leaked water flow at the breach, and breach plugging is achieved. The method is suitable for the situation that the watercourse breach is long, and plugging of the large breach can be rapidly and reliably completed. The method has the advantages of high plugging construction efficiency, good stability and reliability and the like.
本发明公开了一种水流冲力自展开式河道溃口封堵方法，其特征在于，在溃口上游端堤岸上往河道内顺水流方向投放可抽拉的多节套筒式管道结构的封堵管道，封堵管道上端固连在溃口上游端，令封堵管道在河道内受河水冲击而使得各节套筒自行展开，末节套筒超过溃口位置到达溃口下游端并受溃口处外泄水流冲击能够被限位于溃口两端堤岸内侧壁，实现溃口封堵。本发明适用于河道溃口较长的情况，能够快速可靠地完成大型溃口的封堵。具有封堵施工过程效率高，稳定性和可靠性好等优点。
