The invention relates to a large-flow and large-span dike breach blocking device, which effectively solves the problems of difficulty in blocking a dike breach and difficulty in forming long-term effective protection. The large-flow and large-span dike breach blocking device adopts the technical scheme that the large-flow and large-span dike breach blocking device comprises two simply supported beams, wherein the two simply supported beams are stretched across the dike breach side by side from front to back, a plurality of vertical hinge plates are arranged below each simply supported beam, the plurality of vertical hinge plates are uniformly distributed in the length direction of the simply supported beams, each hinge plate is formed in a way that two vertical plates are hinged, a vertical shaft is installed on the upper end of each vertical plate, chutes are formed in the simply supported beams in the length direction, the upper ends of the vertical shafts are arranged in the chutes,a pull rope is arranged on the simply supported beams, and hinged shafts of the hinge plates can be pulled to the simply supported beams by the pull rope, so that the hinge plates are opened. According to the large-flow and large-span dike breach blocking device, the vertical plates rotate and are matched with sandbags and stones so as to gradually limit the water flow, so that a blocking wall can be effectively prevented from being burst, the sandbags are prevented from being washed away, and the effective throttling blocking is quickly established.
本发明涉及一种大流量大跨度决堤口封堵装置，有效的解决了决堤口封堵困难，难以形成长久有效防护的问题；解决的技术方案包括两道前后并排横跨在决堤口上的简支梁，每个下方设有多个竖向的合页板，多个合页板沿简支梁的长度方向均布，每个合页板由两个竖板铰接而成，每个竖板的上端均安装有一个竖轴，简支梁上沿长度方向开有滑槽，每个竖轴的上端均置于滑槽内，简支梁上设有一根拉绳，拉绳可将合页板的铰接轴向简支梁方向拉动，从而使合页板撑开；本发明通过竖板的转动与沙袋石块的配合逐步限制水流量，能够有效的避免封堵墙被冲垮和沙袋被冲走，快速的建立起有效的节流封堵。
