What is geotextile?
Geotextiles, also known as geotextiles, are permeable geosynthetics made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetics. The finished product is cloth, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.
Characteristics of geotextile
1. High strength, due to the use of plastic fiber, it can maintain full strength and elongation under dry and wet conditions.
2. Corrosion resistance. It can resist corrosion for a long time in soil and water with different pH values.
3. Water permeability is good because there are gaps between fibers, so it has good water permeability.
4. Good anti microbial property will not damage microorganisms and insects.
5. The construction is convenient. Because the material is light and soft, the transportation, laying and construction are convenient.
6. Complete specifications: width up to 9 meters. It is the widest product in China, and the mass per unit area is 100-1000g/m2.
Use of geotextile
It is widely used in water conservancy, electric power, mine, highway, railway and other geotechnical projects:
l. Filter material separated by soil layer;
2. Drainage materials for mineral processing of reservoirs and mines, and drainage materials for foundation of high-rise buildings;
3. Anti scour materials for river dams and slope protection;
4. Reinforcing materials for subgrade of railway, highway and airport runways, and reinforcing materials for road construction in marshland;
5. Frost and frost resistant thermal insulation materials;
6. Anti cracking materials for asphalt pavement.
Application field of geotextile
l. It is used as reinforcement in the backfilling 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 to prevent water and soil loss and frost damage of soil mass at low temperature.
4. The isolation layer between ballast and subgrade, or between subgrade and soft foundation.
5. The isolation layer between artificial fill, rockfill or material yard and foundation, and the isolation between different frozen soil layers. Filtration and reinforcement.
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 soil of the retaining wall.
7. Filter layer around the drainage pipe or gravel drainage ditch.
8. The filter layer of water well, relief well or baroclinic pipe in hydraulic engineering.
9. The geotextile isolation layer between the highway, airport, railway road and artificial rockfill and the foundation.
10. The earth dam is drained vertically or horizontally and buried in the soil to dissipate the pore water pressure.
11. The drainage behind the impervious geomembrane or under the concrete cover in the earth dam or earth embankment.
12. The seepage around the tunnel shall be eliminated to reduce the external water pressure on the lining and the seepage around the buildings.
13. Drainage of artificial fill ground sports ground.
14. Roads (including temporary roads), railways, embankments, earth rock dams, airports, sports grounds and other projects are used to strengthen soft foundations.
Classification of geotextiles
Short fiber needle punched nonwoven geotextile can be divided into polyester, polypropylene, nylon, vinylon, ethylene and other needle punched nonwoven geotextiles according to raw materials; It can be divided into ordinary type and composite type according to structure. The varieties of staple fiber needle punched nonwoven geotextiles are designed by the production department according to the market demand.
Laying method of geotextile
1. Manual roll paving shall be used, and the cloth surface shall be flat with appropriate deformation allowance.
2. The installation of filament or staple geotextile usually adopts several methods, such as lapping, stitching and welding. The width of stitching and welding is generally more than 0.1m, and the lap width is generally more than 0.2m. Geotextiles that may be exposed for a long time shall be welded or stitched.
3. Sewing of geotextile: All sewing must be continuous (for example, spot sewing is not allowed). The geotextile must overlap at least 150 mm before overlapping. The minimum distance between the needle and the selvage (the exposed edge of the material) shall be at least 25 mm. The sewn geotextile joint most includes one line of linear locking chain joint method. The suture used shall be a resin material with a minimum tension of more than 60N, and have the chemical corrosion resistance and ultraviolet resistance equivalent to or beyond that of geotextile. Any "missing needle" on the sewn geotextile must be re sewn at the affected place. Corresponding measures must be taken to prevent soil, particulate matter or foreign matter from entering the geotextile layer after installation.
4. During construction, the geotextile on the geomembrane shall be naturally lapped, and the geotextile on the upper layer of the geomembrane shall be welded by seam or hot air. Hot air welding is the preferred method for the connection of filament geotextile, that is, the hot air gun is used to heat the connection of two pieces of cloth at an instant of high temperature, so that their parts can reach the melting state, and a certain external force is immediately used to make them firmly bonded together. In the case that thermal bonding cannot be carried out in wet (rainy and snowy) weather, another method - suture connection method shall be adopted for geotextile, that is, special sewing machine shall be used for double suture connection, and chemical ultraviolet resistant suture shall be used. The minimum width is 10cm when sewing, 20cm when natural lapping and 20cm when hot air welding.
5. For the sewing, the suture with the same quality as the geotextile shall be used, and the suture shall be made of materials with stronger resistance to chemical damage and ultraviolet light.
6. After the geotextile is laid and approved by the site supervision engineer, the geomembrane can be laid.
7. The geotextile on the geomembrane is laid as above after the geomembrane is approved by Party A and the Supervisor.
8. The geotextile of each layer shall be numbered TN and BN.
9. The upper and lower layers of geotextile on the membrane shall be buried in the anchorage groove together with the geotextile.
