Introduction
Flood control sub-dikes are temporary small dikes built urgently on the top of the main dike near the water surface to prevent floodwater from overflowing. They are a type of on-site assembled sub-dike. Typically stored as emergency equipment in national, regional, or provincial warehouses, they are also directly equipped in mobile emergency teams of various provinces and regions.


Main Functions:
Primarily used for emergency flood prevention on soft dikes such as sandy loam, loam, clay, concrete, and asphalt. They address overflow and wave erosion risks on dikes and dams. On one hand, they prevent disasters caused by overflowing when river levels surge beyond the dike’s elevation due to low flood control standards or extreme flooding. On the other hand, they mitigate wave erosion risks on certain dike sections during high water levels in flood seasons when strong winds cause water to wash over the dike top.
Modern flood control sub-dikes are often modified from unit panels to serve multiple purposes. This approach breaks away from traditional methods of constructing sub-dikes, abandoning conventional materials, structures, and construction techniques. They represent a new, fast, cost-effective, and environmentally friendly solution for flood emergency response. Key features include efficient and rapid construction, flexible assembly, strong adaptability, easy storage, low cost, reusability, and environmental sustainability.
