Performance Advantages
Good mechanical properties: It has high tensile strength and tear strength, and can withstand large external forces in different engineering environments, being not easy to deform and damage.
Excellent soil - fixing ability: The three - dimensional structure in the middle can effectively fix soil particles and prevent soil loss. In slope protection projects, it can resist rainwater scouring and wind erosion, maintaining the stability of the slope.
Good water permeability: The structure of the three - dimensional geonet allows water to penetrate freely, which is beneficial to the discharge of groundwater and the air permeability of the soil, avoiding soil softening and the instability of engineering structures caused by waterlogging.
Anti - aging and corrosion - resistance: Made of polymers, it has good ultraviolet - resistance, anti - aging and corrosion - resistance properties, and can maintain the stability of its performance during long - term use, prolonging the service life of the project.
Application Areas
Road engineering: It is used for the reinforcement and protection of road subgrades, improving the bearing capacity and stability of subgrades and reducing uneven settlement. In the treatment of soft soil foundations, the three - dimensional geonet can be used in combination with gravel cushions to form a reinforced cushion, enhancing the bearing capacity of soft soil. At the same time, it can also be used for the protection of road slopes, preventing slope collapses and soil erosion.
Water conservancy engineering: It is widely used in riverbank protection and dam seepage prevention. It can prevent the scouring of riverbanks and dams by water flow, protecting the safety of hydraulic structures. In the protection projects around reservoirs, the three - dimensional geonet can effectively fix the soil and prevent the landslides and bank collapses of the reservoir banks.
Environmental protection engineering: It is used for the covering and slope protection of landfills, preventing the pollution of the surrounding environment by landfill leachate, and also playing a role in preventing the slope collapses of landfills. In the ecological restoration of mines, the three - dimensional geonet can be used to cover abandoned mine pits and tailings ponds, promoting the growth of vegetation and restoring the ecological environment.
