Product Application
1、 In the field of civil engineering
Roadbed and pavement engineering: laid between the soil layers of the roadbed, with the function of "blocking soil and permeability", intercepting soil particles to prevent roadbed settlement, while discharging rainwater or groundwater to avoid cracking and overturning of the pavement due to accumulated water, and improving the service life of the road;
Dams and hydraulic engineering: used for the outer side of the anti-seepage layer of dams or river slope protection. It can filter sediment in water bodies, prevent soil erosion of dams, and discharge accumulated water inside the dam body, reducing the pressure on the dam body and lowering the risk of dam failure.
2、 Greening and Ecological Field
Landscape greening and roof greening: laid under the planting soil, can filter excess water, prevent plant roots from accumulating water and rotting, while maintaining soil permeability and promoting root growth; It can also prevent the loss of planting soil with rainwater and protect the soil structure of green areas;
Slope ecological restoration: Laying on the soil surface of exposed slopes, combined with vegetation planting, can not only fix the soil and prevent soil erosion, but also provide suitable humidity for vegetation growth through permeability characteristics, helping to restore slope ecology.
3、 Environmental Protection and Waste Management Field
Landfill site: As a filtration layer for leachate, it is laid at the bottom and sides of the landfill area, which can filter impurities and suspended solids in the leachate, reduce pollution to groundwater, and assist in leachate collection and discharge, improving the environmental treatment efficiency of the landfill site;
Wastewater treatment plant: used as a filtering auxiliary layer for sedimentation tanks and filters, which can intercept solid particles in wastewater, improve wastewater filtration efficiency, reduce losses of subsequent treatment equipment, and ensure stable operation of the wastewater treatment system.
Geotextile non-woven filter fabric, with its core characteristics of "soil blocking and water permeability, stable protection", is widely suitable for the three core fields of civil engineering, ecological greening, and environmental protection treatment. In practical applications, it can not only solve safety problems such as settlement and dam failure in engineering construction, but also assist in ecological restoration and environmental governance, providing practical solutions for "preventing loss, promoting stability, and reducing losses" in different scenarios. It is a key auxiliary material for improving engineering quality and protecting the ecological environment.
