The invention discloses a device for quickly constructing
flood control sub-embankments and an operation method thereof. The device is formed by splicing a plurality of rubber bags, each rubber bag comprises a bag body, each bag body comprises a bag surface and a bag bottom, each bag bottom comprises a bag body bottom and an outwards-extending section, each outwards-extending section extends out of the bottom of the corresponding bag body, a water filling port is formed at the top of each bag surface, a water outlet is formed at the position, close to the corresponding bag bottom, of each bagsurface, and a plurality of
pile holes are formed in the outwards-extending sections and matched with fixing piles. The rubber bags are simple to arrange and facilitate water filling,
flood control sub-embankment construction is rapid, the number of needed personnel is small, materials are few, the bag bodies can be recycled, no waste materials exist, environmental
pollution cannot be caused, andthe low-carbon, environment-friendly and ecological saving type
flood control technology is achieved. The bags are filled with water to form a water retaining dam, and water is resisted with water. Meanwhile, the water in the bags provides acting force for water retaining of the bag bodies, and the bag bodies are filled with the water, so that dual purposes of the water are achieved. Flood controlsub-embankment scour prevention and large embankment scour prevention are combined into a whole, flood overflowing can be prevented, a large embankment can be prevented from being scoured, and the safety of the large embankment is guaranteed.
