It seems you're referring to a "water stopper barrier" or "waterstop barrier." Water stopper barriers or waterstop barriers are typically structures or materials designed to prevent the flow of water or provide a barrier to control water in various settings. They are used to manage water in construction, flood control, environmental protection, and other applications. Here are a few examples of water stopper barriers:
1. **Flood Barriers**: These are temporary or permanent structures used to protect properties and areas from flooding. Flood barriers can be made of materials like sandbags, metal, or rubber, and they are deployed to redirect or block floodwater.
2. **Waterstop in Construction**: In construction, a water stop or waterstop is a material used to prevent the passage of water through joints, cracks, or connections in concrete structures like dams, basements, and retaining walls.
3. **Silt Barriers**: These are used in construction or environmental applications to contain sediment and prevent it from spreading into water bodies during construction activities or soil erosion.
4. **Coastal Barriers**: In coastal areas, barriers or seawalls are used to protect against storm surges and coastal erosion.
5. **Stormwater Management**: Various barriers and structures are employed to manage stormwater, including detention basins, retention ponds, and other systems designed to control the flow of water.
6. **Levees and Dams**: In some cases, large-scale water stopper barriers are created in the form of levees and dams to control water flow, store water, or protect against flooding.
The specific type and design of a water stopper barrier depend on the intended application and the volume of water it needs to control or redirect. These barriers play a crucial role in protecting property, managing water resources, and mitigating the impact of floods and environmental changes.
