Background

At present, for the breach of a dam, a flat plugging method, a vertical plugging method or a mixed plugging method is generally adopted for plugging emergency construction, and specific plugging modes such as sunken ship closure, sunken willow silt falling and the like are adopted in combination with specific situations. The flat plugging method comprises the steps of throwing and filling materials layer by layer upwards along the axis of a selected dam to meet the plugging requirement; the vertical blocking rule is that the construction is carried out gradually by starting from different sides of the port door and advancing towards the water along the axis of the dam so as to achieve the purpose of gradually reducing the port door; the mixed plugging method is a comprehensive mode of the two plugging modes.

However, the above methods consume too much manpower and material resources, and the entire breach must be robustly built to play a role, so that the building time is long (3-4 days at a high speed and 7-8 days at a low speed), and the efficiency is low. During the breach period, the life safety and property safety of people around the breach can be seriously affected by flood disasters.
