Polyester Filament Geotextile
Filament geotextile has good mechanical function, good water permeability, anti-corrosion, anti-aging, and has the functions of isolation, anti-filtration, drainage, protection, stabilization, reinforcement, etc. It can adapt to uneven base layers and resist construction external forces. Damage, creep is small, and the original function can still be maintained under long-term load.It is mainly used in engineering fields such as reinforcement and isolation, with simple construction and convenient use.
Application:
(1) Used as reinforcement in the backfill of the retaining wall, or as a panel for anchoring the retaining wall. Construction of wrapped retaining walls or abutments.
(2) Reinforce the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.
(3) Increase the stability of the gravel slope and the reinforced soil to prevent soil erosion and freezing damage to the soil at low temperatures.
(4) The isolation layer between the road ballast and the roadbed, or the isolation layer between the roadbed and the soft foundation.
(5) Isolation layer between artificial fill, rockfill or material field and foundation, isolation between different frozen soil layers, back filtration and reinforcement.
(6) The filter layer of the upstream dam surface in the initial stage of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill of the retaining wall.
(7) The filter layer around the drainage underdrain or around the gravel drainage underdrain.
(8) The filter layer of water wells, pressure relief wells or oblique pipes in water conservancy projects.
(9) The isolation layer of geotextiles between roads, airports, railway slag and artificial rockfills and the foundation.
(10) Vertical or horizontal drainage inside the earth dam, buried in the soil to dissipate pore water pressure.
(11) Drainage behind the anti-seepage geomembrane in earth dams or earth embankments or under the concrete cover.
(12) Eliminate the seepage around the tunnel, reduce the external water pressure on the lining and seepage around the buildings.
(13) Drainage of artificial ground foundation sports ground.
(14) Roads (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields and other projects are used to strengthen weak foundations.
