Description

Technical Field

[0001] The invention relates to the technical field of flood control plugging and sealing, and in particular to a dam assembled flood control plugging and sealing device. Background Art

[0002] For dike breaches, especially those in the Yangtze River Basin, which are more common, rapid and effective rescue and reinforcement measures must be taken. For example, in the first few hours of a breach, the breach section can be promptly blocked by throwing in plugging materials, such as prefabricated blocks and caissons, to prevent the breach from further expanding; then the breach of the dike can be scientifically monitored and reinforced. The early blocking of the breach section is of great significance in the entire rescue process. The safe and efficient blocking can control the further development of the dangerous situation and ensure a safe flood season. Due to the large water flow of the breach, ordinary plugging materials such as sandbags will be washed away by the water flow, resulting in plugging failure. The plugging efficiency is too low. If the breach is not blocked in time, the breach will become larger and larger, endangering personal safety.

[0003] The shortcomings of the existing technology in plugging and sealing are that the efficiency is slow and the sealing effect is poor.
