Geotextiles are divided into woven geotextiles and non-woven geotextiles 人氣: 1120 回覆: 0


1. Drain
Geotextiles are used as vertical and horizontal drainage systems for earth dams polyester nonwoven geotextile factory price, and as a barrier to the rise of underground capillary water in areas sensitive to frost. Capillary barrier layer, used to allow salt and lye to flow in dry land; and used as the foundation layer of hinged concrete block slope protection.

2. Anti-filtering
Under the gravel base of sidewalks and airport roads or around the gravel drainage layer under railway tracks, around underground drainage pipes with holes, in the production of landfill leachate, protect the geonet to prevent soil particles from invading the protective geosynthesis Material and soil particles invade.

3. Steel bars and protective materials
Used for soft soil foundations of embankments, railways, waste landfills and sports fields, used to make polypropylene nonwoven geotextile for sale bags, used to reinforce the slopes of earth dams and embankments, used to improve the bearing capacity of shallow foundations, used to strengthen pile foundations Piles are used to prevent the foundation soil from penetrating the geomembrane, and to prevent impurities or stone layers in the landfill from being pierced by the geomembrane. Due to the high friction resistance, the slope of the composite geomembrane is more stable.

4. Isolation between different materials
Between subgrade and foundation, between railway subgrade and road, between landfill and gravel base, between geomembrane and sandy drainage layer, between foundation and embankment, between foundation soil and foundation pile, sidewalk parking lot And below the playground, between the low-grade filter layer and drainage layer, between different areas of the earth dam, between the new and old asphalt layers.

The above is the filament nonwoven geotextile for sale effect we described in detail for you. In fact, geotextiles are divided into woven geotextiles and non-woven geotextiles. The former is woven from monofilament or multifilament or film, while the cut flat yarn is woven. The latter consists of short fibers or long fibers randomly spread into cotton wool, and then mechanically entangled (needling) or thermally bonded or chemically bonded.
