Lianqi Network Industry [galfan/galvanized/plastic-coated Options Available] Reno Mattresses, Ecological Slope Protection Cages for River Channel Treatment
Lianqi Mesh Industry [Galfan/galvanized/plastic-coated options available] Reno Mattress, ecological slope protection cage for river regulation, resistant to scouring and corrosion, certified by national standards
The Reno Mattress of Anping Lianqi Gabion Mesh Products Co., Ltd. is a flexible engineering material specially designed for water conservancy protection and ecological restoration. It is made of machine-woven double-twisted hexagonal metal mesh to form a flat cushion-like structure, usually with a thickness of 0.17-0.3 meters. Double partitions are set every 1 meter inside to enhance stability. Its core advantages are reflected in the following aspects:
I. Innovation in structure and materials
1. Flexible anti-deformation design
The double-twisted hexagonal mesh holes endow the mattress with excellent ductility, allowing it to adapt to uneven settlement of the foundation without cracking. The double partition structure (steel wire diameter 2.0mm) is formed by folding the whole mesh, without splicing. Its overall performance far exceeds the traditional single partition design, effectively preventing the collapse of stones and improving the scouring resistance.
2. Multiple anti-corrosion systems
- Galvanized steel wire: The zinc layer thickness is 80-120g/㎡, suitable for dry inland environments, with a service life of 8-12 years.
- Galfan (zinc-5% aluminum-rare earth alloy): The coating thickness is 200-300g/㎡, and its corrosion resistance is 3-5 times that of ordinary galvanized steel. Its service life in seawater environment can reach 20-25 years.
- Plastic-coated steel wire: Galvanized or Galfan steel wire is coated with an environmental-friendly PVC layer of 1.0-2.0mm, which isolates corrosive media and can be customized in color to meet the needs of sensitive environments such as drinking water sources.
All materials have passed the 3000-hour salt spray test and meet the standards of GB/T 343-2013 and EN 10223-3.
II. Advantages in engineering performance
1. Scouring resistance and flood control ability
The flexible structure formed after filling with stones can withstand the impact of high-speed water flow of 5-6m/s. In projects such as the governance of the Yangtze River tributaries, it has remained stable after being tested by a once-in-20-year flood. The double partition design enables the mattress to maintain its structural integrity in complex environments such as tidal areas and frost heave areas.
2. Ecological restoration function
The porosity of 25-30% promotes the natural exchange between water and soil. The gaps between stones provide habitats for aquatic organisms. After covering the surface with soil, the vegetation coverage rate can reach 80% within 3 years, and the fish population increases by 2 times, achieving the ecological balance of "fish underwater and green on the shore".
3. Economy and construction efficiency
The initial cost is 40% lower than that of concrete slope protection, the construction efficiency is increased by 30%, and the later maintenance cost is only 20% of that of traditional rigid structures. The mattress can be folded for transportation and assembled and filled on-site without large machinery, which is especially suitable for winter construction.
3. Wide application scenarios
1. Water conservancy projects
Riverbank slope protection, sea dike protection, and reinforcement of reservoir dams can effectively prevent water scouring and bank slope collapse. For example, the Galfan Reno mattress was used in the ecological governance project in the Xiongan New Area, achieving the dual goals of improving flood control standards and restoring wetland ecology.
2. Transportation and municipal works
Slope protection for highways and railways, and construction of urban landscape rivers, taking into account both safety and aesthetics. In the Chengdu Jinjiang Greenway project, the grass - green PVC - coated mattress blends with the surrounding environment, becoming an ecological barrier for the hydrophilic leisure space.
3. Special environment governance
The 316L stainless steel material is used in tidal areas. In frost - heaving areas, the flexible structure is utilized to adapt to freeze - thaw cycles. In the rivers around chemical industrial parks, PVC - coated mattresses are used to isolate pollution and ensure the long - term safety of the project.
4. Quality and service guarantee
Anping Lianqi Gabion Mesh Products Co., Ltd. strictly implements the ISO 9001 quality management system. Each batch of products comes with an authoritative report from the Water Resources Ministry Testing Center, covering 12 core indicators such as tensile strength and coating adhesion. An innovative full - process electronic traceability system is introduced. By scanning the code, you can trace the complete data chain from raw material procurement to finished product delivery, and the defective rate is controlled below 0.1‰. At the same time, full - cycle services from scheme design, stone gradation suggestions to construction guidance are provided.
The Lianqi Reno mattress, with its dual value of "flexible protection + ecological restoration", is reshaping the construction concept of modern water conservancy projects and has become a benchmark product that takes into account safety, environmental protection and economy.
