geotextile meaning
What is geotextile fabric? Geotextile is a water-permeable geosynthetic material produced by weaving technology in cloth shape, also known as geotextile fabric. With the development of the times, geotextiles are used in soil and water protection and landscaping to green our living environment. Geotextiles are usually laid before covering the soil. Geotextiles can penetrate water or filter sediment to protect foundations. Thus, many garden projects or greening Environment projects will use geotextile fabric.
The role of geotextiles in greening environment
1. The function of geotextile filtration: when the water flows from the washing soil layer into the coarse soil layer, the good air permeability and water permeability of the needle-punched geotextile is used to make the water flow through and intercept soil particles, spun yarn and small stones. etc., to maintain the stability of soil and water engineering.
2. The role of geotextile protection: effective concentration of stress diffusion, transmission, or decomposition, to prevent the soil from being damaged by external forces, and to protect the soil.
3. The role of geotextile drainage: Geotextile is a good water-conducting material, it can form a drainage channel inside the soil, and remove the excess liquid and gas in the soil structure.
4. The role of geotextile isolation: Polyester staple fiber needle-punched geotextiles are used to isolate building materials with different physical properties (such as soil and sand, soil and concrete, etc.). It prevents two or more materials from being lost or mixed, maintaining the structure and function of the material, and enhancing the bearing capacity of the structure.
5. The role of geotextile reinforcement: the use of needle geotextiles to enhance the tensile strength and resistance to deformation of the soil, increase the stability of the building structure, and improve the quality of the soil.
6. Anti-puncture effect of geotextile: The combination of geotextile and geomembrane becomes a composite waterproof and anti-seepage material, which plays the role of anti-puncture.
High tensile strength, good permeability, air permeability, high-temperature resistance, freezing resistance, aging resistance, corrosion resistance, and no moth-eaten.
Three ways to identify the quality of geotextiles
1. Look at the color of the geotextile. The colors of geotextiles that meet the production standards are pure white, black, light gray, light blue, color, and so on. Some inferior geotextiles will be mixed with other materials in the production, the color does not look particularly pure, and some will have some color spots. Also, improper rinsing will also affect the color of the geotextile. For geotextiles of the same color, the quality of the needle-punched density is better.
2. Look at the weight of the geotextile. If the quality of the whole roll of geotextile is too light, it means that the texture of the material is not pure, and there may be a phenomenon of cutting corners. Of course, in a humid environment, the geotextile will also get wet and become heavier, which is easy to fool the merchants, so everyone must keep their eyes open when purchasing.
3. Look at the thickness of the geotextile. Geotextiles are made of synthetic fibers by needle punching or weaving, and the thickness is usually uniform during processing. When purchasing geotextiles, we must pay attention to the uniformity of thickness in the vertical and horizontal directions.
Geotextile application engineering scope
What is geotextile fabric used for? Geotextiles are used in a wide range of applications. Generally speaking, there is the following purpose of geotextile：
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 flexible pavement, repair cracks on the road, and prevent road reflection cracks.
3. Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage of soil at low temperatures.
4. The barrier layer between the road ballast and the subgrade, or the barrier layer between the subgrade and the soft subgrade.
5. The barrier layer between artificial fill, rockfill, or material field and foundation, and the barrier between different permafrost layers. Anti-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 barrier layer of geotextiles between roads, airports, railway tracks, and artificial rockfills and the foundation.
10. The internal drainage of the earth dam is straight or horizontal, and it is buried in the soil to dissipate the pore water pressure.
11. Drainage behind the anti-seepage geomembrane in earth dams or earth embankments or under the concrete cover.
12. Exclude water seepage around the tunnel, reduce the external water pressure on the lining, and seepage around each building.
13. Drainage of artificial ground foundation sports ground.
14. Highways (including temporary roads) are used to strengthen fragile foundations in projects such as railways, embankments, earth-rock dams, airports, and sports fields.
