With the increasing frequency of global floods and extreme weather events, urban flood control, riverbank protection, and heavy-duty flood defense have become crucial components of infrastructure safety. Compared to traditional sandbags or temporary protective measures, modern engineering is increasingly adopting more efficient and robust flood barrier systems to build reliable flood defenses for communities, transportation routes, and critical infrastructure.

        A bastion flood barrier refers to a barrier system used to block floods, mitigate the impact of water flow, and protect critical areas.It typically consists of a combination of high-strength metal mesh and filler materials, and can be deployed quickly to form a robust protective wall. Its core structure and technological principles are widely applied in disaster prevention engineering worldwide.

        Ⅰ. The basic structure and working principle of flood control barriers.

        Modern flood barriers are primarily composed of high-strength metal mesh, reinforced connectors, and internal filling materials. Zhengyang Company's flood barriers utilize welded metal mesh panels combined with high-quality non-woven geotextile lining, forming a sealed unit structurally. The outer metal mesh bears the water pressure and external impact, while the inner geotextile effectively reduces filler leakage.

        During installation, the barriers are unfolded and connected to form a continuous wall. Then, local filling materials such as sand, soil, and gravel are added according to site requirements to create a robust flood protection wall.

        Ⅱ. Technical advantages of flood control barriers

        1. Rapid Deployment and Efficient Response: The bastion flood barrier can be deployed and filled in a short time, reducing the labor intensity of on-site personnel and significantly shortening the construction period, allowing for the rapid construction of protective barriers in emergency situations.

        2. The Zhengyang flood control barrier features a high-standard zinc-aluminum coating treatment, meeting international anti-corrosion standards, and can maintain stable performance in long-term outdoor environments.

        3. Multi-layered protection: The flood barriers can not only withstand the impact of floodwaters but also the impact of floating debris carried by the current. Some systems support vegetation cover, achieving both ecological landscape and protective value.

        Ⅲ. Typical application scenarios for flood control barriers

        1. Urban Flooding and River Embankments: In low-lying urban areas, along riverbanks, and in areas with weak drainage systems, flood barriers can serve as emergency defenses to reduce the impact of flood spread on community life.

        2. Infrastructure and Transportation Protection: Highways, high-speed rail lines, and bridge sections are often threatened by floods. Deploying flood barriers can effectively prevent water erosion of roadbeds and protect the continuous operation of transportation systems.

        3. Industrial Parks and Critical Facilities: For critical infrastructure such as power plants, substations, and warehousing facilities, implementing reliable flood barrier measures helps ensure supply chain stability and production safety.

        Ⅳ. Selection and design considerations for bastion flood control barriers.

        1. Barrier Height and Length: Flood height and water flow estimations are the basic basis for design. The protective height should be determined based on local topography and historical flood data, ensuring the barrier length covers the affected area.

        2. Material Specifications and Coating Treatment: The wire diameter and coating type of the metal mesh directly affect the corrosion resistance and durability of the barrier. High-quality materials significantly improve overall protective performance.

        3. Connection Method and Stability Considerations: Multi-unit barriers are combined into a complete wall structure through connectors; therefore, reliable connection structures should be prioritized in the design.
