Product Application
Water conservancy engineering
In dam construction, geotextile is laid between the dam body and the foundation to play a filtering role, intercept soil particles, and prevent leakage of the dam body due to water flow erosion; At the same time, its drainage function can timely discharge the accumulated water inside the dam body, reduce water pressure, and ensure the stability of the dam structure. In channel engineering, it can isolate different soil layers, avoid channel collapse, and reduce the erosion of water flow on the bottom of the channel.
Highway and Railway Engineering
During the construction of highway subgrade, geotextile is laid between the subgrade soil and the sand and gravel cushion layer to isolate the two and prevent soil particles from infiltrating the cushion layer and causing deformation of the subgrade; Its reinforcement effect can enhance the bearing capacity of the roadbed and reduce road surface settlement. Laying geotextile underneath railway tracks can cushion the impact of train travel, protect track foundations, and extend the service life of railways.
Municipal Engineering
In sewage treatment plants, geotextiles can be used as filter layers in sedimentation tanks and sludge treatment areas to intercept solid particles in sludge and purify water quality; In a landfill site, it can isolate the landfill material from the surrounding soil, prevent harmful substances from infiltrating and polluting groundwater, and assist in the discharge of leachate generated by the landfill site.
Agricultural and Environmental Engineering
In agricultural irrigation channels, geotextiles can prevent channel leakage, improve water resource utilization, and protect channel slopes from water erosion. In ecological restoration projects, such as river regulation, laying geotextiles can stabilize riverbeds, provide a good environment for the growth of aquatic plants, and help restore ecosystems.
Geotextiles play a crucial role in various fields such as water conservancy, highways and railways, municipal engineering, agriculture and environmental protection, thanks to their functions of filtration, drainage, reinforcement, and protection. It can not only improve the stability and durability of engineering structures, but also contribute to environmental protection and resource conservation, making it an indispensable and important material in various types of engineering construction.
