Flood Control Lead Wire Welded Stone Gabion Mesh, Reno Mattress River Bank Protection Gabion Box

Razor wire mesh, galvanized razor wire mesh, hot-dipped galvanized razor wire mesh. A descriptive explanation of razor wire mesh is a wire mesh cage used to contain stones, a wire or polymer mesh structure designed to secure filled stones in place. It is a structural method for riverbank protection and ecological management in today's civil engineering projects. Razor wire mesh is a woven or welded structure made of wire. Both structures can be electro-galvanized, hot-dipped galvanized, or hot-dipped galvanized aluminum, with the woven wire boxes optionally coated with PVC. Using weather-resistant and hard stones as fill material, it will not break down quickly due to abrasion in the stone box or stone cage. Stone cages filled with different types of block stones have different characteristics. Angular block stones can interlock well with each other, and the stone cages filled with them are less prone to deformation.
Reinforcement Mesh Structure Requirements: The reinforcement mesh is mechanically woven from high corrosion-resistant, high-tensile, and ductile low-carbon steel wire (galvanized iron wire) or wire coated with PVC. The box-like structure made from this mesh is known as a gabion box. According to ASTM and EN standards, the diameter of the low-carbon steel wire used varies according to engineering design requirements, generally ranging from 2.0 to 4.0 mm. The tensile strength of the reinforcement mesh wire should be no less than 38 kg/m², and the weight of the metallic coating should typically be more than 245 g/m². The diameter of the edge line of the gabion mesh should generally be larger than the wire diameter. The length of the double twisted section must not be less than 50 mm to ensure that the metallic coating and PVC coating on the twisted wire are not damaged.
Advantages of Gabion mesh structure:
The flexible structure can adapt to the changes in the slope without being damaged, offering even better safety and stability than rigid structures.
2. Strong abrasion resistance, capable of withstanding water flow speeds up to 6 m/s.
3. The structure is inherently permeable, exhibiting strong tolerance to the natural action and filtration of groundwater. Suspended particles and silt in the water settle into the crevices of the fill stones, thereby promoting the growth of natural vegetation and gradually restoring the original ecological environment.
Riprap Mesh Applications:
Wire mesh baskets are used for slope support, foundation pit support, rock face mesh shotcrete on mountains, slope vegetation (greening), and isolation barriers for railways and highways. They can also be made into boxes and pads, used for erosion protection of rivers, dams, and sea dikes, as well as for reservoir and river sedimentation control nets. Due to their ecological protection characteristics, wire mesh baskets are affectionately called ecological mesh, and they are a structural method for the management of water conservancy projects and ecological environment restoration in China.
Control and guide rivers and floods
Severe river disasters occur when water currents erode riverbanks, causing flooding that leads to substantial loss of life and property, as well as massive soil erosion. Therefore, when addressing such issues, the application of the eco-grid structure becomes one of the solutions, as it provides long-lasting protection for riverbeds and riverbanks.
2. In channel canal bed construction:
Constructing channels involves stabilizing slopes and riverbeds. Therefore, the use of ecological mesh structures, a primary method adopted in the modification of many natural rivers and excavation of artificial channels over the past century, is essential. It effectively protects riverbanks or riverbeds, controls water flow, and prevents water loss, particularly in environmental protection and water quality maintenance, where it serves to restore the ecological environment.
3. In terms of revetment and slope protection:
The gabion mesh structure is a highly successful example in riverbank protection and slope toe stabilization, fully leveraging the advantages of the ecological mesh, achieving ideal effects that cannot be attained by other methods.

Reinforced stone笼nets demonstrate protective advantages in hydraulic engineering applications:
1. Ideal ecological construction and ecological restoration functionality
The pores within the stone笼and matting facilitate water flow, promoting natural exchange between water and soil, creating a habitat for aquatic life and microorganisms, thereby enhancing the water body's self-purification ability and protecting and improving water sources and quality. The voids in the filling material, either artificially layered with soil or naturally deposited, create conditions for landscaping and vegetation. Even without sowing seeds, plants will naturally grow, achieving optimization, beautification of the environment, and improvement and restoration of the ecological environment.
2. Excellent water permeability
Retaining walls and slope protection laid with wire mesh baskets, filled with loose material, which has numerous pores, facilitating the drainage of backfilled soil and groundwater in the subsoil beneath the slope. Once surface water infiltrates the soil, it can be quickly drained through the masonry, effectively lowering the groundwater level and reducing the groundwater pressure behind the wall and beneath the slope. The structure of stone笼 mesh baskets in the treatment of landslides and the prevention of mudslides ensures timely drainage, reducing the likelihood of wall damage. Additionally, the wall's excellent deformation capability effectively mitigates the impact of sudden external forces.
3. Stable and comprehensive permeability function.
The stone笼mesh is a mechanically woven double twisted grid structure; localized damage will not compromise the integrity of the entire cage. The stone笼material features moderate deformation, uniting the entire project as a whole without the need for seams. Even if uneven settling occurs, the overall structure will not crack or encounter serious issues.
4. Simpler construction methods.
The stone笼 mesh process can be factory-produced according to design intent, creating semi-finished products. On the construction site, the assembly and shaping are done according to the design drawings, then laid on prepared slopes or excavated foundation pits to form retaining walls or constructed into box culverts. Filling material is added, and the cover mesh is installed, completing the structure. The operation is simple, minimally affected by weather, and suitable for mechanized work, ensuring construction quality while speeding up the project. During the construction process of a construction unit, affected by the weather, workers originally assigned to build stone retaining walls were transferred to assemble the stone mesh slope protection.
5. Landscape Effect
The ease of assembly and variety of colors in the gabion mesh structure allows for a wide range of structural design options, catering to different regional landscape requirements. Combined with planted lawns and flower trees, what we present is a green retaining wall or slope.
6. Excellent corrosion and durability resistance.
The steel wire used in stone笼 mesh is coated with hot-dipped aluminum zinc, providing a more stable surface finish that effectively reduces oxidation of the wire. After being treated with a resin film process, it boasts corrosion resistance, static electricity prevention, aging resistance, and oxidation resistance, extending its service life. Tests have shown that when plastic is soaked in 30% hydrochloric acid solution for 10 days, there is no discoloration or cracking. This indicates that the material is reliable even in highly polluted areas. The lifespan of the wire coated with resin film can reach 70 years.
7. Strong resistance to erosion and wind wave attacks.
The gabion mesh structure is highly effective as a slope protection or retaining wall in rivers with high flow velocities, offering strong resistance to erosion. According to relevant experiments, the erosion coefficient of the gabion mesh structure is twice that of general rock pitching protection projects. Even if the boulders within the gabion mesh mat are displaced by the water flow, the deformed box-like structure achieves a new equilibrium, maintaining overall integrity without damage. The gabion mesh structure is flexible, with gaps between the stones or other materials inside the boxes, which, when hit by wave crests, shatters the spray, reducing the impact force of the wave pressure. As wave crests recede, the gaps in the boxes disrupt the vacuum suction force of the waves, further reducing the impact on the protection project. Additionally, the overall structure can self-adjust slightly under the force of waves, effectively preventing cracks in the wall.
Common structure forms of stone笼net:
1. Gabion Box - Constructed from heavy-duty hexagonal wire mesh, this wire mesh box is typically assembled from four folded pieces of heavy-duty hexagonal mesh. One large hexagonal mesh is folded to form the four large faces of a rectangular prism, with two smaller hexagonal mesh pieces at each end and a dividing mesh in the middle. The gabion box can also be made into triangular or trapezoidal shapes, with the embankments constructed from these boxes having an inclined plane on a single level.
Riprap baskets, often used in hydraulic engineering for retaining walls, are constructed from stacked baskets of stones, typically ranging from 0.5 to 1.0 meters in size. These riprap basket walls are primarily used on steep slopes to control mudslides, prevent landslides, and protect the subgrade of roads and railways. The reason for using riprap baskets is their unique ecological benefits. A thin layer of soil applied to the surface of the protective structure allows for vegetation, as the gaps between the stones accommodate soil, promoting root development and creating a favorable ecological environment. Even without applying soil, over time, the gaps between the stones will accumulate dirt, fostering the growth of herbaceous plants and forming a natural ecological habitat. Once the riprap baskets are produced, they can be捆扎compressed for packaging to save space.
Section 2: Gabion matting is a heavy-duty hexagonal wire mesh cut and folded into metal mesh boxes. The thickness of the gabion matting ranges from 0.15 to 0.5 meters, significantly less than the length and width of the gabion boxes. The gabion matting is divided into several cells by single or double separators. To enhance the structural strength of the gabion matting, the diameter of the wire at the edges of the mesh plates is relatively thick. Primarily used for riverbanks, embankments, road embankments, and coastal slope protection structures. It not only prevents riverbanks from being eroded by water currents and waves but also achieves natural convection between the water body and the soil below the slope, achieving ecological balance. Sprinkling soil with gabion matting allows for the planting of green vegetation, which can enhance the landscape greening effect on the slope.
Section 3: Gabion Retaining Walls are soil-retaining structures composed of stacked layers of gabion baskets. The components of a gabion retaining wall are filled with stones of similar size proportions within the wire mesh baskets, which results in a certain porosity. Due to the gaps between the stones, soil and water beneath the masonry and slope can be drained, thus lowering the water level and reducing the ground water pressure behind the wall and below the slope. Timely drainage minimizes the likelihood of the retaining wall being damaged, significantly extending its lifespan. Additionally, the wall baskets are made of wire mesh, allowing for some deformation. Moreover, the stones can also slide against each other, which enhances the retaining wall's ability to absorb sudden external forces.
Four. Roadstone笼网, available in two types: one is for road protection, such as constructing a stone-filled retaining wall with stone-filled cages along the road's side to withstand floods and safeguard the road; and using stone-filled cages to reinforce the roadbed on its sides. The other type is during road construction, placing heavy-duty hexagonal wire mesh as reinforcement in the subgrade or during cement road paving, embedded within the cement to prevent cracking.
Five. Stone笼Rolls, woven into rolls of 30 to 50 meters, are directly laid on slopes for slope protection, preventing soil erosion and rock falls. They can also be used for slope support, foundation pit support, rock surface mesh spraying, slope vegetation (greening), railway and highway isolation guardrails, as well as erosion protection for rivers, dams, and sea dikes.
Operation of Stone笼Mesh:
1. Operation of gabion mesh sinking, first involves sinking the gabion mesh woven from wire. It can also be electroplated and coated with PVC (polyvinyl chloride), and PVC gabion mesh sinking can also be used for revetment and toe protection.
2. Stone Boxes (Box-like Stone Cages). Wire mesh stone cages are more flexible than welded ones, hence their performance in accommodating settlement and load is different. Although care must be taken when filling with stone materials to ensure the stones are packed tightly, it is sometimes believed that rigid stone boxes are easier to fill, especially for non-standard shapes like bends or areas prone to significant settlement. In such cases, where woven wire or polymer mesh structures can deform without losing strength, these types of structures are often preferred.
3. The internal filling of the stone笼 mesh is composed of weather-resistant, hard stones that will not quickly break due to abrasion in stone boxes or stone笼 arrangements. Stone笼 mesh filled with different types of block stones exhibits varying characteristics. The angular block stones interlock well with each other, making the filled stone笼 less prone to deformation. Therefore, it is more effective in anti-shear retaining walls than round stones and also facilitates the connection of the stone笼. The general size of the filling is 1.5 times the average mesh size. Individual block stones are not less than the standard mesh size (commonly used woven stone笼 sizes are 60mm x 80mm to 100mm x 120mm) and generally not more than 200mm in standard size. For block stones placed away from the outer surface of the stone笼 and within the interior, the size requirements for small block stones may sometimes be relaxed.
4. Internal Filling. Mechanical filling is generally faster and cheaper, but it does not offer the same level of control as manual filling. For decorative retaining walls, a good appearance and a dense structure should be achieved. When using either method, the filling material must completely fill the wire mesh baskets. The filling must be properly compacted to minimize gaps, ensuring good contact between individual stones, as tightly as possible, to reduce the likelihood of stone movement within the baskets. Both polygonal and round stones can be tightly packed when the filling size is within the normal range, and some soil can be added as well.
