A brief introduction to geotextile

A brief introduction to geotextile

1. Work cloth is often used for foundation laying. On the one hand, it can ensure that the water and soil are not lost, and on the other hand, it can also play a role of reinforcement. 

2. Geotextiles will also be used in water conservancy projects. However, anti-seepage geotextiles are used here. Its main function is to prevent seepage, prevent water from eroding into the dam and prevent it from bursting.

3. Geotextiles can also be used in the aquaculture industry, and its main function is isolation, that is, to prevent groundwater and soil from polluting the aquaculture organisms and so on.

4. Short-filament non-woven geotextiles and polyester filament non-woven fabrics are more widely used, mainly used in projects such as water conservancy, municipal administration, dams, road maintenance, and daily landfills of garbage dumps.


5. Polyester geotextile: Polyester geotextile uses polyester material. Polyester material has relatively strong water resistance. It is generally used for waterproofing in fish ponds, garbage dumps and other places. It is more practical. The price of polyester is low in price and cost, and it can be used in a wide range to reduce costs. .

6. As for other things, such as anti-seepage of garbage dumps, application of reservoirs, anti-seepage of artificial lakes and anti-seepage of underground tunnels, etc.

non woven fabric

Although the application range of geotextiles is very wide, careful people will find that geotextiles are correspondingly applied more in some anti-seepage projects, and of course there are many applications in road engineering. But no matter what kind of engineering project, it requires the service life of geotextile to be long enough, that is to say, the durability of geotextile must be good.

In order to prevent strong winds from blowing and damaging the covered geomembrane, heavy compacts should be set on the geomembranes. The compacts can be selected according to local conditions. At present, most of the choices are cement blocks, car tires, geotextile bags of soil, large pebbles, etc. . In some places, the garbage dump is located at the location of the air outlet. Not only must the geomembrane be ballasted, but also the anchor ditch must be set. The anchor ditch has a cross-sectional size of 1000×1000mm, and the spacing is 30 meters parallel to the membrane direction. After the ditch is filled with soil, in order to prevent Rainwater washes away the fill in the ditch, and then covers the anchor ditch with a geomembrane that is 200mm wider on both sides of the anchor ditch, and it should be welded with the flat geomembrane as a whole.
