Let me explain to you the function and use of geotextiles

(1) Isolation between different materials

Between the roadbed and the foundation; between the roadbed and the road silicon; between the landfill and the gravel base; between the geomembrane and the sandy drainage layer; between the foundation and the soil of the dam; between the foundation soil and the pile; between the sidewalk Between filters and drainage layers with poor inclination under parking lots and playgrounds; between different areas of earth dams; between old and new asphalt layers.

2) Ribs and protective materials

It is used for the soft foundation of dykes, railways, landfills, and stadiums; for the production of geotechnical packages; reinforcement of dams, earth dams, and slopes is used as foundation reinforcement in karst areas, and foundation pile cap reinforcement for improving the bearing capacity of shallow foundations. Prevent the foundation soil from piercing the geomembrane; prevent impurities and stone layers in the landfill from piercing the geomembrane; high frictional resistance stabilizes the slope of the composite geomembrane.

3) Inverse filtering

Under gravel foundations of pavement and airport roads, or under concrete of railway tracks; around gravel drainage layers; around subterranean perforated drains; under landfills where water seeps; protects geotextiles against intrusion of soil particles ; Protect geotechnical materials and prevent the intrusion of soil particles.

4) drainage

As the horizontal drainage of the soft foundation preloading dike bottom of the vertical and horizontal drainage system of the earth dam; in the frost-sensitive area, as the partition layer for the rise of underground capillary water; as the capillary barrier layer for the flow of saline and alkali liquid in the field; Base.

What is the main use of geotextiles?

Most of the uses of geotextiles: for railway subgrade engineering reinforcement, highway maintenance, gymnasium, safety protection for weirs, water conservancy construction isolation, tunnels, coastal beaches, reclamation, environmental protection, greening gardens and other engineering projects, waterproof and moisture-proof effect : It is a kind of waterproof and moisture-proof material, which is made of coating epoxy resin or rubber and other waterproof and moisture-proof materials on the surface of the composite geotextile material, or wraps the composite geotextile material and plastic film, and then combines the water-proof It is a waterproof and moisture-proof material made of three layers. The geotextile impermeable membrane is usually wrapped in a thin form with anti-cloth and plastic film. It can be made into one cloth, two cloth and one film or three cloth and one film according to the requirements of the project. The thickness of non-proof cloth and plastic film can also be determined according to the requirements, and it can also be wrapped with thick non-proof cloth and plastic film. The actual effect of the water, the work will be more.

The actual effect of the geotextile When the filtered water flows from the soil layer of the washing material to the soil layer of the coarse material, the needle-punched geotextile has excellent air permeability and water permeability, and through the flowing water, it can reasonably prevent soil granular materials, spun yarns, small gravel materials, etc. Efforts to stabilize civil and water engineering projects, the substantive effect of non-woven fabrics Drainage Non-woven fabrics are excellent water-conducting materials, which can form drainage channels inside the sediment and discharge excess liquid in the sediment structure. Actual Effects The needle-free geotextile is used for the reinforcing rib to increase the yield strength and stress resistance of the sediment, improve the stability of the building structure, and improve the quality of the sediment product.
