Short Description:
High – density polyethylene geonet is a kind of geosynthetic material mainly made of high – density polyethylene (HDPE) and processed with the addition of anti – ultraviolet additives.
High – density polyethylene geonet is a kind of geosynthetic material mainly made of high – density polyethylene (HDPE) and processed with the addition of anti – ultraviolet additives.
Characteristics
High strength: It has high tensile strength and tear resistance, and can bear large external forces and loads. In engineering applications, it can effectively enhance the stability of soil. For example, in the reinforcement of highway and railway subgrades, it can bear the loads of vehicles and other without deformation.
Corrosion resistance: High - density polyethylene has excellent chemical stability and good corrosion resistance to chemical substances such as acids, alkalis and salts. It can be used for a long time under different soil and environmental conditions, and is not easy to be corroded and damaged. It is suitable for some engineering environments with corrosive media, such as industrial waste landfills.
Anti - aging property: After adding anti - ultraviolet additives, it has good anti - aging performance and can resist the radiation of ultraviolet rays in sunlight. When exposed to the natural environment for a long time, it can still maintain the stability of its performance and prolong the service life. It can be used for long - term open - air projects, such as geotechnical projects in desert areas.
Good flexibility: It has certain flexibility and can adapt to the changes of different terrains and the deformation of soil. It combines closely with the soil and can deform with the settlement or displacement of the soil without cracking due to the small deformation of the soil. For example, in the treatment of soft soil foundations, it can better combine with the soft soil and play a reinforcing role.
Good permeability: The geonet has a certain porosity and good water permeability, which is conducive to the drainage of water in the soil, reduces the pore water pressure, and improves the shear strength and stability of the soil. It can be used in some projects that require drainage, such as the drainage system of dams.
Application areas
Road engineering: It is used for the reinforcement and protection of highway and railway subgrades, improving the bearing capacity and stability of subgrades, reducing the settlement and deformation of subgrades, and prolonging the service life of roads. It can also be used in the base and sub - base of pavements to enhance the overall performance of the pavement structure and prevent the occurrence and expansion of pavement cracks.
Water conservancy engineering: In the construction of dams in water conservancy projects such as rivers, lakes and reservoirs, it can be used for the slope protection, toe protection and seepage prevention projects of dams to prevent the scouring and erosion of the dam by water flow, and improve the anti - seepage performance and stability of the dam. It can also be used for the lining and reinforcement of channels to reduce the seepage and soil erosion of channels.
Slope protection engineering: It is used to protect all kinds of slopes, such as soil slopes and rock slopes. By laying high - density polyethylene geonet and combining with vegetation planting, it can effectively prevent the collapse, landslide and soil erosion of slopes and protect the ecological environment of slopes.
Landfill engineering: As part of the liner system and cover system of landfills, it plays the role of seepage prevention, drainage and protection, preventing the pollution of soil and groundwater by landfill leachate, and also protecting the stability of the cover layer to prevent rainwater scouring and garbage flying.
Other fields: It can also be applied to engineering fields such as mines, tailings dams, airport runways and parking lots to play the roles of reinforcement, protection and drainage, improving the quality and safety of the project.
