Geotextiles are new building materials. They are made from synthetic fiber of high-molecular polymer, namely the dacron, acrylic, chinlon, etc. Geotextiles have functions of seepage control, filtration, dewatering, separation, reinforcement, protection, seal, etc.
Properties of geotextiles are as follows.
1. At present, geotextiles are made from synthetic fibers, namely the chinlon, dacron, polypropylene fiber and polyethylene fiber which all have high corrosion resistance.
2. Geotextiles are permeable. So they perform well in filtration and separation.
3. Because of the incompact structure, geotextiles perform well in dewatering.
4. Geotextiles have high anti-puncture ability. So they perform well in protection.
5. Geotextiles have high friction coefficient and strength of extension which means they can be used for reinforcement.
Geotextiles are new building materials. They made from synthetic fiber of high-molecular polymer, namely the dacron, acrylic, chinlon, etc. According to manufacturing method, geotextiles can be divided into two categories, namely the woven geotextile and non-woven geotextile. The geotextiles have functions of seepage control, filtration, dewatering, separation, reinforcement, protection, seal, etc. Compared with common stone and concrete, geotextiles have properties of low cost, simple construction?technology, short construction period, good anti-seepage effect, channel efficiency. Geotextiles can be used for filtration in dams and revetments, for separation and seepage control in channels, for separation and dewatering in roads, railways and runways, for reinforcement and dewatering in slopes, retaining walls and pavements, for treatment in soft grounds of the ports, causeways and wharfs, for separation and seepage control in landfills, ash dams of heat-engine plants and tailings dams of dressing mills.
Geotextiles are now widely used in the field of construction of infrastructure and will be used in broader fields.
