At present, the common method for rescuing the dike breach in the flood season is mainly used for restraining and plugging the dike breach by throwing and filling soil stones near the breach or throwing special large-volume filling bodies such as a steel lattice gabion, a steel bar gabion, a concrete tetrahedron and the like, but the prior method has the following outstanding problems:
(1) the traditional earth and stone throwing and filling technology is generally suitable for the conditions of small breach range, low flow rate and small difference between an internal water head and an external water head of a dam. For the dam which runs at a high water level in a flood season, once a breach occurs, the water flow at the breach is turbulent (if the flow rate exceeds 4m/s), the conventional throwing filler is extremely easy to wash away by the water flow and is difficult to fix, the breach is difficult to block, and the rescue success rate is low.
(2) When the dike breach is large and the water situation is complex, large-volume blocking materials such as steel lattice gabions, steel reinforcement gabions, concrete tetrahedrons and the like need to be thrown. These materials need to be specially made in advance, and are long in time consumption and high in cost. Meanwhile, a large transport vehicle and special hoisting equipment are needed, and the method is difficult to implement in some areas with limited conditions.
