Geotextile application scenario
Geotextiles are widely used in water conservancy, hydropower, highways, railways, ports, airports, sports venues, tunnels, coastal beaches, reclamation, environmental protection and other engineering fields.
(1) It is used as reinforcement in the backfill of retaining wall or for anchoring the panel of retaining wall. Build wrapped retaining wall or abutment.
(2) Reinforce the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.
(3) Increase the stability of gravel slope and reinforced soil, and prevent water and soil loss and freezing damage of soil at low temperature.
(4) The isolation layer between ballast and subgrade, or between subgrade and soft foundation.
(5) Isolation layer between artificial fill, rockfill or material yard and foundation, isolation, inverted filtration and reinforcement between different frozen soil layers.
(6) The filter layer of the upstream dam surface at 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) Filter layer around concealed drainage pipe or gravel drainage ditch.
(8) Filter layer of water well, relief well or inclined pressure pipe in hydraulic engineering.
(9) The isolation layer of geotextile between highway, airport, railway ballast and artificial rockfill and the foundation.
(10) The internal vertical or horizontal drainage of the earth dam is buried in the soil to dissipate the pore water pressure.
(11) Drainage behind impervious geomembrane or under concrete cover in earth dam or embankment.
(12) Eliminate the water seepage around the tunnel and reduce the external water pressure borne by the lining and the water seepage around each building.
(13) Artificial fill foundation drainage of sports ground foundation.
(14) Roads (including temporary roads), railways, embankments, earth rock dams, airports, sports fields and other projects are used to strengthen weak foundations.
Filament geotextile has good mechanical function, good water permeability, corrosion resistance, aging resistance, isolation, inverted filtration, drainage, protection, stability, reinforcement and other functions, can adapt to uneven base, can resist external force damage during construction, has small creep, and can still maintain its original function under long-term load.
Characteristics of filament geotextile:
Strength - under the same gram weight specification, the tensile strength in all directions is higher than that of other needle punched non-woven fabrics;
Anti ultraviolet light - it has extremely high anti ultraviolet ability;
Extremely high temperature resistance - the high temperature resistance reaches 230 ℃, and the structure is still intact and the original physical properties are maintained under high temperature;
Permeability and plane drainage - the geotextile is thick and needle punched, which has good plane drainage and vertical permeability, and can still maintain this performance after many years;
Creep resistance - geotextile has better creep resistance than other geotextiles, so it has good long-term effect. It can resist the erosion of common chemicals in soil and the corrosion of gasoline, diesel, etc;
Ductility - geotextile has a good elongation under a certain stress, so that it can adapt to uneven irregular foundation surface;
Technical characteristics of filament geotextile: the geotextile is thick, which can ensure the three-dimensional void ratio of the geotextile and is conducive to the realization of excellent hydraulic properties. The bursting strength of geotextile has great advantages, especially suitable for retaining walls and embankment reinforcement. The index of geotextile exceeds the national standard, and it is an excellent geotechnical reinforcement material.
Short silk geotextile: it is produced with PP or pet short fiber as the main raw material and non-woven process. It has the functions of isolation, filtration, drainage, reinforcement, protection, maintenance and so on.
