Characteristics of 200 g Geotechnical Filter
1. Geotechnical filter screen has strong drainage (equivalent to one meter thick gravel drainage),
The 2.200g geotextile filter screen has high tensile strength,
3. The special geotextile filter screen for landfill can reduce the probability of geotextile embedding into the mesh core and maintain long-term stable drainage.
4. Geotechnical filter screen bears high pressure load for a long time (it can bear about 3000Ka compression load);
5. Filter Screen Standard of Corrosion Resistance, Acid and Alkali Resistance and Long Service Life.
Geotechnical filter screen is made of single polymer or permeable geotextile made of polymer material compounded by mechanical consolidation, chemical and other bonding methods. The standard geotextile filter screen shall comply with the urban construction standard cj/t437-2013. The longitudinal fracture strength of geotextile filter screen shall be ≥45kn and the transverse fracture strength shall be ≥ 45kN whether it is used for groundwater drainage or leachate drainage in landfill.
Geotechnical filter screen is a kind of black mesh geotechnical material. Geotechnical filter screen is a new type of landfill filter material produced from polymer materials such as polypropylene or polyethylene. It is mainly used in underground drainage filtration, seepage filtration on the surface of sealed landfill and leachate filtration collection.
