Geonet, as an important geosynthetic material, is made from synthetic polymers and processed to form a specific porous structure. With its unique structure and excellent performance, it is widely used in multiple fields.
1、 Road engineering
In road construction, geonets are commonly used for roadbed treatment and pavement reinforcement. Laying geonets on the roadbed can diffuse stress and reduce roadbed settlement. Due to its interlocking with the fill soil, it constrains the lateral displacement of the soil and enhances the stability of the roadbed. Especially in soft soil foundations, it can effectively improve bearing capacity, reduce post construction settlement, and extend the service life of roads.
Laying geonets between the base and surface layers of the pavement can enhance the overall integrity of the pavement structure, disperse traffic loads, and reduce the occurrence and propagation of pavement cracks. For the renovation of old roads, geonets can delay reflection cracks, improve road performance, and save maintenance costs.
2、 Slope protection
Geonet is widely used in slope protection. Laying it on the slope can effectively fix the soil on the slope and prevent soil erosion. Its porous structure is conducive to vegetation growth, with plant roots interwoven with geonets to form a stable composite and enhance slope stability. In the ecological protection of soil slopes and rock slopes, geonets provide an attachment foundation for vegetation, promote vegetation restoration, achieve the combination of engineering protection and ecological greening, beautify the environment, and improve the slope’s resistance to erosion.
3、 River and Coastal Protection
In river management, geonets are used for riverbank protection to resist water erosion. Laying on the riverbank, it can disperse the energy of water flow, reduce the erosion of the riverbank by water flow, and protect the stability of the riverbank. In coastal protection engineering, geonets are combined with other materials such as block stones and precast concrete blocks to resist wave impacts and prevent coastal erosion and retreat.
4、 Landscape greening
In the field of landscaping, geonets create favorable conditions for plant growth. Used for flower beds and green spaces, it can prevent soil compaction, maintain loose and breathable soil, and promote the growth and development of plant roots. In roof greening, geonets have both drainage and soil retention functions, which not only remove excess rainwater but also retain the water and nutrients needed for plant growth, reducing roof loads and creating a suitable environment for plant growth.
5、 Solid waste treatment
Geonets play an important role in solid waste treatment projects such as landfills. Laying at the bottom and slope of the landfill site, auxiliary drainage system, timely removal of leachate, reducing pollution to the surrounding environment. At the same time, enhance the structural stability of the landfill site to prevent accidents such as garbage landslides.
In summary, geonets are widely used in various engineering projects for their reinforcement, protection, drainage, and soil stabilization functions, improving engineering quality and stability, and promoting ecological environment protection and restoration. With the development of material technology, the performance of geonets is constantly optimized, and their application prospects will be broader.
