Geotextile of geotechnical materials used in the repair and seepage prevention work of tailings pond
With the gradual strengthening of the national awareness of environmental protection, the construction of tailings landfill has put forward higher requirements. The traditional anti-seepage method, cement concrete, stone stacking, waterproof coating and so on are no longer applicable, accompanied by the rapid development of geosynthetic materials, and widely used in various fields. Geosynthetics are divided into four categories: geotextile, geomembrane, geotechnical composite materials and geotechnical special materials, among which new HDPE geomembrane, geotextile, composite geomembrane, bentonite waterproof blanket, composite drainage network and other geotechnical materials are also more and more common in the mine tailings pond environment. They play an important role in the tailings repair and seepage prevention work with their excellent seepage prevention performance, construction convenience and excellent durability. Today to bring you is the share of geotextile.
Geotextile is divided into short fiber needle prick geotextile and polyester filament geotextile
Short fiber needle nonwoven geotextile is polypropylene or polyester staple fiber as the main material, the finished product is cloth, has good mechanical function, good permeability, and corrosion resistance, aging, with isolation, filter, drainage, protection, stability, reinforcement, etc, can adapt to the uneven base, can resist construction force damage, creep, long-term load can keep the original function. Can be widely used in railway, highway, sports venues, embankments, reclamation, environmental protection and other projects, and can play a unique effect in the project. The width is 1-6m, and the gram weight is 90g-800g / m2.
filament geotextile is filament unbonded non-woven geotextile or polyester filament geotextile, which is a permeable geosynthetic material made of polyester slice through melting spinning needle. For the reinforcement, reinforcement, reverse filtration isolation and drainage of highway, railway, dyke, coastal beach and other projects, filament geotextile is especially suitable for salt-alkali marsh and landfill sites. The finished product is cloth, with a width of 1-6 meters and a length of 50-100 meters.
