Stone笼mesh, galvanized stone笼mesh, hot-dipped galvanized stone笼mesh; a descriptive explanation of the stone笼 is a wire mesh cage used for containing stones. It is a wire or polymer mesh structure that secures filled stones in place. It is a structural method for riverbank protection and ecological management in today's civil engineering projects. The wire cage is a mesh or welded structure made of wire. Both structures can be electro-galvanized, hot-dipped galvanized, or hot-dipped galvanized aluminum. The woven wire baskets can be coated with PVC. Using hard, weather-resistant stones as fill material, they do not break down quickly due to abrasion in the stone baskets or stone笼. Stone笼 filled with different types of block stones has varying characteristics. Polygonal block stones can interlock well together, and stone笼 filled with them is 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 is usually above 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 and PVC coatings 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 erosion resistance, capable of withstanding water flow speeds up to 6 m/s.
3. The structure is inherently permeable, with strong包容性 towards the natural action and filtration of groundwater. Sediments and silt in the water are able to settle in the crevices of the fill stones, thereby promoting the growth of natural vegetation and gradually restoring the original ecological environment.
Razor Wire Mesh Applications:
Hexagonal wire mesh is used for slope support, foundation pit support, rock face mesh shotcrete on mountains, slope vegetation (greening), and isolation and protection barriers for railways and expressways. It can also be made into box-like structures and mesh pads, which are used for erosion protection of rivers, embankments, and sea dikes, as well as for reservoir and river diversion net boxes. Known for its ecological protection features, it is affectionately termed "ecological mesh" and is a structural method used in China for the management of water conservancy projects, protection, and ecological environment restoration.
Control and guide rivers and floods
Severe river disasters occur when the flowing water erodes riverbanks, causing flooding that leads to massive losses of life, property, and soil erosion. Therefore, in addressing these issues, the use of the ecological mesh structure is one of the solutions, providing long-lasting protection for riverbeds and riverbanks.
2. In the construction of the riverbed in the channel canal:
The construction of channels involves the stability of slopes and riverbeds. Therefore, the use of ecological mesh structures has been the primary method adopted in the reconstruction of many natural rivers and the excavation of artificial channels over the past century. It provides effective protection for riverbanks or riverbeds, controls water flow, and prevents water loss, particularly in environmental protection and water quality maintenance, with the function of restoring 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 utilizing the advantages of the ecological mesh to achieve ideal effects that other methods cannot accomplish.
Galvanized Stone Lattice Mesh Material Classification:
Galvanized Steel Wire: Low carbon steel wire with a diameter of 2.0MM-4.0MM, tensile strength not less than 380Mpa. The wire is protected with hot galvanizing, with the thickness of the galvanized layer tailored to customer requirements, and the galvanizing weight can reach up to 300g/m2 (electro-galvanized zinc coating is only about 10g).
2. Zinc-5% Aluminum-Mixed Rare Earth Alloy Wire (also known as Galfan) Wire: This is a new material emerging internationally, offering corrosion resistance over three times that of traditional pure zinc-plated wire. The wire diameter ranges from 1.0MM to 3.0MM, with a tensile strength of not less than 1380Mpa.
3. Galvanized Steel Wire Coated with PVC: Low-carbon steel wire, coated with a layer of PVC protective layer on the surface, then woven into various specifications of hexagonal wire mesh.
Zinc-5% Aluminum-Mixed Rare Earth Alloy Steel Wire Coated with PVC: The zinc-5% aluminum-mixed rare earth alloy steel wire is coated with a layer of PVC for protection, and then woven into various specifications of hexagonal wire mesh.
Razor wire cages demonstrate protective advantages in hydraulic engineering applications:
Ideal ecological construction and restoration functions
The voids 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 capabilities 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 growth, even without sowing seeds, leading to the optimization, beautification, and restoration of the environment.
2. Excellent permeability
Retaining walls and slope protection laid with wire baskets, filled with loose material, which contains numerous pores. This facilitates the drainage of water from the soil behind the masonry and from the soil layer beneath the slope protection. Once surface water infiltrates the soil, it can be quickly排出 through the masonry, effectively lowering the groundwater level and reducing the groundwater pressure behind the wall and beneath the slope. The wire basket structure in the treatment of landslides and prevention of mudslides ensures timely drainage to minimize wall damage, while the wall's excellent deformation capacity 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 cause overall destruction of the box. The stone笼material has moderate deformation characteristics, uniting the entire project into a cohesive whole without the need for seams. Even if uneven settlement occurs, the overall structure will not crack or experience severe issues.
4. Simpler construction methods.
The stone笼 mesh process can be factory-produced as semi-finished products according to design intentions. On-site, the components are assembled and shaped according to the design plans, then laid on prepared slopes or excavated trenches to form retaining slopes or box culvert retaining walls. Filling material is added, and the cover mesh is installed to complete. The operation is simple, minimally affected by weather conditions, and suitable for mechanized operations, ensuring both construction quality and speeding up the project进度. During a construction process, affected by the weather, the construction unit transferred workers originally assigned to building stone masonry retaining walls to construct stone笼 mesh retaining slopes.
5. Landscape Effect
The easy assembly of the stone笼 net structure and the variety of colors offer us a wide range of structural design options, meeting different regional landscape requirements. Combined with grass lawns and flower trees, we are presented with a green retaining wall or slope.
6. Excellent corrosion and durability resistance.
The steel wire used in stone笼mesh material is coated with hot-dipped aluminum zinc, ensuring a more stable surface finish that effectively reduces oxidation of the wire. After being treated with a resin film, it boasts corrosion resistance, static dissipation, aging resistance, and oxidation resistance, resulting in a longer service life. Tests have shown that when plastic is soaked in a 30% concentration of hydrochloric acid for 10 days, there is no discoloration or cracking. This indicates that the material is reliable even in highly polluted areas. The steel wire coated with the resin film can have a service life of up to 70 years.
7. Strong resistance to erosion and storm surge.
The gabion mesh structure is highly effective for erosion control and retaining wall projects in rivers with strong currents. Experimental evidence shows that the anti-erosion coefficient of the gabion mesh structure is twice that of general rock throwing protection projects. Even if the boulders within the gabion mat are displaced by the water flow, the deformed box structure achieves a new equilibrium, ensuring overall integrity is not compromised. The gabion mesh structure is flexible, with gaps between the stones or other materials inside the boxes. When waves crash onto the peaks, the spray is crushed, reducing the impact force of the wave pressure. As the wave peaks recede, the gaps in the boxes disrupt the vacuum suction force of the waves, further reducing the damage to the protective works. Additionally, the overall structure can self-adjust slightly under the force of waves, effectively preventing cracks from forming in the wall.
Common Structure Forms of Gabion Mesh:
1. Gabion Mesh Box - It is a wire mesh box made by cutting and folding heavy-duty hexagonal mesh. Typically, it consists of a box assembled from 4 folded heavy-duty hexagonal mesh panels, with one large hexagonal mesh folded to form 4 large faces of a rectangular prism, two small hexagonal mesh pieces at each end, and a dividing mesh panel in the middle. The gabion mesh boxes can also be made into triangular or trapezoidal shapes, and when stacked, these gabion mesh boxes form a dam with the inclined surface on a single plane.
Gabion baskets are commonly used in hydraulic engineering for retaining walls. These retaining walls are constructed from stacked gabion baskets, each ranging from 0.5 to 1.0 meters in size. Gabion basket walls are primarily used on steep slopes to control mud and rock flows, prevent landslides, and for the protection of highway and railway subgrades. The reason for using gabion baskets is their unique ecological function. Simply sprinkling a little soil on 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 adding soil, over time, the gaps between the stones will fill with silt, fostering the growth of herbaceous plants and forming a natural ecological habitat. After the gabion baskets are produced, they can be bundled and compressed for packaging to save space.
Section 2: Gabion mat, a heavy-duty hexagonal wire mesh cut and folded into a metal mesh box, with a thickness ranging from 0.15 to 0.5 meters. This type of engineering component has a thickness much smaller than the length and width of the gabion box. The gabion mat is divided into several cells by single or double separators. To enhance the structural strength of the gabion mat, the diameter of the steel wire at the edges of the mesh plates is relatively thick. It is primarily used in river channels, riverbanks, road embankments, and coastal slope protection structures. It not only prevents riverbanks from being eroded by water currents and waves but also achieves a natural convection function between the water body and the soil below the slope, achieving ecological balance. The gabion mat, when scattered with soil, allows for the planting of green vegetation, which enhances the landscape greening effect on the slope.
Section 3: Gabion Retaining Walls are constructed by stacking layers of gabion baskets. The components of a gabion retaining wall are filled with stones of similar size within the wire mesh baskets, which creates a certain porosity. Due to the gaps between the stones, soil and water beneath the masonry and slope can be drained, thereby reducing the water level and the ground water pressure behind the wall and below the slope. Prompt drainage minimizes the risk of wall destruction, significantly extending the lifespan of the retaining wall. Additionally, the wall baskets are made of wire mesh, allowing for some deformation. Moreover, the stones can also slide against each other, thus enhancing the wall's ability to withstand sudden external forces.
4. Roadstone wire mesh, available in two types: one is for road protection, such as constructing a wire mesh embankment alongside the road to resist floods and safeguard the road; and reinforcing the subgrade with wire mesh boxes. The other type is used during road construction, where heavy-duty hexagonal mesh is placed as reinforcement within the subgrade or beneath the concrete pavement to prevent cracking.
V. Stone笼Rolls, woven into sheets ranging from 30 to 50 meters, rolled into coils, 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 face meshing for shotcrete, slope vegetation (greening), isolation barriers for railways and highways, and erosion protection for rivers, dams, and sea dikes.
Operation of Gabion Mesh:
1. Stone笼weaving operation: First, submerge the woven wire stone cage. It can also be electroplated and coated with PVC (polyvinyl chloride). PVC stone cage weaving can also be used for bank protection and toe protection.
2. Stone Boxes (Box-shaped Stone Lattices). Mesh stone boxes are more flexible than welded ones, so their performance in adapting to settlement and load is different. Although filling the stone materials carefully is necessary to ensure the stones are packed tightly, it is sometimes considered that rigid stone boxes are easier to fill. For non-standard shapes, such as bends or areas prone to significant settlement, where the woven wire or polymer lattice structures can deform without losing strength, these structures are often preferred.
3. The internal filling of the stone笼 is composed of weather-resistant, hard stones, which will not break down quickly due to abrasion in stone boxes or stone笼 arrangements. Stone笼 with different types of block stones exhibit varying characteristics. Angular block stones interlock well, making the stone笼 filled with them less prone to deformation. Therefore, they are more effective in anti-shear retaining walls than round stones and also facilitate the connection of 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 inside, the size requirements for small block stones may sometimes be relaxed.
4. Internal Filling. Mechanical filling is generally faster and cheaper, but it lacks the precision of manual filling. For decorated retaining walls, it should produce a better appearance and form a compact structure. When using either method, the filling material must completely fill the cage. The filling material must be properly compacted to minimize gaps, ensuring good contact between individual stones, as tightly as possible, and reduce the possibility of stone movement within the cage. Both polygonal and round stones can be tightly packed when the filling material is within the normal size range, and some soil can be added as well.
