Gabion Wire Mesh is a mesh-like box structure made of high-strength and corrosion-resistant steel wires. After being filled with natural stones such as gravel, it forms a flexible retaining system and is widely used in water conservancy, transportation, and municipal engineering fields.
1. Flexible Structure with Strong Deformation and Impact Resistance
Gabion wire mesh adopts a double-line twisted weaving process, and the whole box has flexible characteristics. It can adaptively adjust its shape according to terrain subsidence and foundation deformation, without cracking or collapsing due to stress concentration like rigid concrete structures.
- When facing impact loads such as floods and debris flows, the flexible structure can disperse impact force and offset external forces through the occlusion between boxes, making it particularly suitable for slope protection, river bank protection and other scenarios vulnerable to water flow scouring.
- It is suitable for complex terrains. There is no need for large-area leveling of the construction site, and it can be directly laid on steep slopes, irregular riverbeds and other areas, reducing the cost of preliminary earthwork projects.
2. Water and Air Permeability to Reduce Engineering Hydrological Pressure
The porosity of gabion mesh box reaches 30%-40%, and the porous structure formed after filling with stone materials has good water permeability:
- Rainwater or river water can penetrate freely, avoiding the formation of hydrostatic pressure on the back of the structure, and effectively preventing the risk of slope and dam sliding or breaching caused by excessive water pressure.
- The water permeability can maintain the natural moisture content of the soil, protect the stability of the foundation soil, and reduce soil erosion and water loss.
3. Convenient Construction, Short Construction Period and Controllable Cost
- Modular assembly: Gabion wire mesh can be transported in a folded state. On-site, it only needs to be spliced, assembled and filled with stone materials to form a finished product. No large-scale construction machinery is required, and the construction can be completed manually, which is especially suitable for construction sites in remote mountainous areas with inconvenient transportation.
- Easy access to raw materials: Filling stone materials can be sourced locally (such as river crushed stones, basalt, etc.), greatly reducing the cost of material transportation; the later maintenance is simple, and local damage can be directly repaired without overall demolition and reconstruction.
- Construction period advantage: Compared with concrete pouring projects, the construction period of gabion wire mesh can be shortened by more than 50%
4. High Strength and Corrosion Resistance with Long Service Life
The surface of gabion wire mesh steel wire is treated with anti-corrosive processes such as hot-dip galvanizing, Galfan (zinc-aluminum alloy) coating, and PVC coating, and different coatings can be adapted to different corrosive environments:
- The zinc coating weight of hot-dip galvanized gabion wire mesh is ≥240g/㎡, and its service life can reach 15-20 years in ordinary outdoor environments;
- The corrosion resistance of Galfan coating is 2-3 times that of hot-dip galvanizing, and its service life exceeds 30 years in marine tidal zones and high-salinity areas;
- PVC coating has both anti-corrosion and wear-resistant properties, which can resist stone friction and acid-base soil erosion, and prolong the overall service life of the structure.
