Chinese non-woven geotextile is a geosynthetic material made of synthetic fibers (such as polypropylene, polyester, etc.) through a non-woven process. It has good filtration, isolation, reinforcement, drainage and other functions, and is one of the indispensable and important materials in civil engineering. According to different manufacturing processes, non-woven geotextiles can be divided into needle-punched non-woven fabrics, thermal bonded non-woven fabrics, chemically bonded non-woven fabrics, etc.
In China, with the continuous advancement of infrastructure construction, the demand for non-woven geotextile continues to grow. Non-woven geotextile are not only used in the construction of large-scale projects such as roads, railways, dams, tunnels, airports, etc., but are also widely used in many fields such as environmental protection, agriculture, construction, landfills, infiltration control, underground pipe networks, etc.
Chinese non-woven geotextile Main application scenarios
Road and railway construction
China non-woven geotextiles are widely used in road and railway construction. Its main functions include separating different soil layers, preventing soil mixing, enhancing foundation stability, and improving bearing capacity. Specific applications include:
Roadbed reinforcement and stabilization; In soft soil areas, the roadbed is prone to settlement. The use of non-woven geotextiles can effectively isolate soft soil and fill, prevent mixing, and improve the bearing capacity and stability of the roadbed.
The isolation and reinforcement of non-woven geotextiles can ensure that the roadbed soil does not deform excessively under the action of external forces, increase the friction of the soil, and thus improve the strength and durability of the road surface.
Drainage system; Chinese non-woven geotextile have good water permeability, can effectively remove moisture from the roadbed, reduce the accumulation of water under the road surface, and avoid water erosion and settlement of the roadbed.
Prevent soil erosion; In coastal, mountainous and complex terrain sections, the use of non-woven geotextiles can prevent soil erosion, especially during construction, to protect slopes and slopes from water erosion.
Railway infrastructure; Non-woven geotextiles are often used in railway construction to separate soil layers, enhance the stability of track foundations, and prevent track deformation, especially for unstable soil environments.
Water conservancy and reservoir projects; Non-woven geotextiles are widely used in water conservancy and reservoir projects, mainly in the fields of dam reinforcement, drainage systems, flood discharge channels, river protection, etc.:
Dam reinforcement and anti-seepage; Chinese non-woven geotextile are often used in the construction of anti-seepage layers of reservoir dams. By combining non-woven geotextiles with waterproof membranes, water penetration can be prevented, the difference in moisture inside and outside the dam can be reduced, and soil erosion and damage to the dam structure can be prevented.
River protection and protection; In the process of river management, non-woven geotextiles are used as an isolation layer between soil and sand to enhance the soil’s anti-scouring ability and reduce the erosion of river banks by water flow. Especially in extreme weather conditions such as heavy rains and floods, it can effectively improve the stability of river banks.
Drainage system of water conservancy project; non-woven geotextiles can provide good drainage performance for water conservancy facilities, prevent excessive water pressure from affecting dams and embankments, and maintain the safety of reservoirs and embankment structures.
Slope stabilization and reinforcement; non-woven geotextiles play an important role in slope stabilization and reinforcement, especially in complex terrain and geological environments, and can provide effective protection:
Slope protection; in areas such as high slopes, landslides, and landslides, non-woven geotextiles are used to reinforce slopes to prevent soil and stone sliding, providing better stability and safety.
Slope greening; non-woven geotextiles are also commonly used in greening projects, especially in mountain greening and ecological restoration. By combining vegetation soil protection, it promotes plant root growth and enhances soil water stability.
Landfill and environmental protection projects; non-woven geotextiles are also widely used in landfills, sewage treatment and environmental protection. Non-woven geotextiles have good water permeability, corrosion resistance and aging resistance, and are indispensable materials in environmental protection projects.
Landfill anti-seepage system; non-woven geotextiles are used as anti-seepage layers in landfills to prevent garbage from infiltrating into groundwater sources and protect the surrounding environment from pollution. It is usually used in combination with waterproof membranes and other materials to form a multi-layer anti-seepage system.
Sewage treatment and drainage systems; non-woven geotextiles are used in sewage treatment plants and drainage systems to filter impurities and particles in the water, keep the water clean, and prevent the spread of water pollution.
Soil and water conservation and sand control; non-woven geotextiles are used in ecological and environmental protection projects such as desert control and soil and water conservation, which can effectively reduce wind and sand erosion and soil erosion, restore vegetation coverage, and promote the improvement of the ecological environment.
Agricultural applications; the application of non-woven geotextiles in the agricultural field is mainly reflected in the following aspects:
Agricultural land coverage; non-woven geotextiles can cover farmland, inhibit weed growth, while retaining soil moisture and improving the growth environment of crops.
Greenhouse construction; non-woven geotextiles are used for laying the ground in greenhouses, which can improve the drainage effect in the greenhouse, improve soil aeration, and promote the healthy growth of plant roots.
Agricultural irrigation: Non-woven geotextiles are used in the construction of irrigation systems to effectively control water flow, prevent groundwater leakage, and reduce water waste.
Chinese non-woven geotextile play a crucial role in supporting ambitious infrastructure and environmental projects. With applications spanning from road construction and environmental protection to agriculture and slope stabilization, these geosynthetics are indispensable in many sectors. The growing demand for non-woven geotextiles, driven by China’s expanding urbanization and environmental initiatives, will continue to offer significant opportunities for both domestic and international manufacturers. As technology evolves, the production of more advanced and sustainable will further enhance their role in the future of construction and infrastructure projects.
