polyester filament geotextile is the use of polyester by the spinning needle directly into the way of consolidation, product specifications from 80-800g/m2 arbitrary choice, it is a kind of application of geosynthetics in geotechnical engineering and civil engineering, is through the polyester filament network and consolidation method is made, the fiber arrangement into a three dimensional structure. In addition to having good mechanical properties, also has good vertical drainage performance and good extensibility and high resistance to biological, acid and alkali resistance, aging resistance and so on chemical stability. At the same time, also has a wide aperture range, tortuous pore distribution, good permeability and filtration performance. polyester filament geotextile application: dam and slope protection of water conservancy engineering filter, isolation, seepage channel; highway, railway, airport runway foundation isolation, filtration, drainage, slope, retaining wall and the pavement reinforcement, drainage port engineering; soft foundation treatment the dike, beach, harbor wharf and breakwater reinforcement, drainage; polyester filament geotextile has been widely used in the field of infrastructure construction, and gradually be applied more widely in the field of water conservancy engineering:
seawall, dyke, Hu Di standard engineering; reservoir reinforcement engineering; reclamation project; flood control. highway and railway air harbor engineering: soft foundation strengthening treatment; slope protection; pavement anti reflection crack structure layer; drainage system; green belt separation. electrical engineering: basic project of nuclear power plant ash dam; thermal power project; hydropower project.
