1.Geotextile Technology and Market
Geotextile is made of polyester fiber as the key raw material, which is refined through multiple processes such as opening, carding, laying net and needle punching. Its quality varies depending on the depth of fiber color, and can usually be divided into national standard, Dahua, Sinochem, Small, and black and green geotextiles. The darker the fiber color, the lower the index 。In the current background that geotextiles are widely used in many fields, you may be curious: 200 g What is the existence of the national standard geotextile? Next, let’s explore the answer together.
Geotextiles are known for their excellent penetration, filtration, and isolation properties. Its material is soft, not only flexible, but also excellent breathability. The standard width range is 2-6 meters, and can also be customized according to specific construction site needs, making The construction process is more convenient and efficient 。
2. Application fields of geotextiles
Next, we will explore the application of geotextiles in various fields 。This material plays a key role in multiple industries and scenarios with its excellent permeation, filtration and isolation properties. Its material is soft and breathable, which not only has outstanding flexibility, but can also be customized according to specific needs, thus greatly improving the convenience and efficiency of construction. Next, let’s take a look at which areas geotextiles shine.
- In backfill soil, geotextile can be used for the support of reinforcement bars, or as a material for anchoring retaining wall panels.
- It can enhance the stability of flexible pavement, effectively repair pavement cracks, and prevent the occurrence of pavement reflection cracks.
- For gravel slopes and reinforced soils, geotextiles can increase their stability, thus preventing soil erosion and low-temperature soil freezing damage.
- It can also be used as an isolation layer between subgrade, or an isolation material between subgrade and soft foundation to ensure the stability and durability of the project.
- In the foundation of artificial filling, rockfill or material yard and isolation layer, geotextile can play the role of filtration and reinforcement to ensure construction safety.
- Geotextile is also of great significance for the reverse filter layer of the initial upstream dam surface of ash storage dam or tailings dam, and the reverse filter layer of the backfill drainage system of retaining wall.
- Around pipes or gravel drains, geotextile can be used as a filter layer to protect the drainage system from impurities.
- In water conservancy projects, geotextile is used as a water filtration layer to ensure smooth water flow and stability of the project.
- It can also isolate roads, airports, railways and artificial rockfills from foundations, preventing the interaction between different media.
- For vertical or horizontal drainage inside the earth dam, geotextile can be effectively buried in the soil to dissipate the gap water pressure and ensure the safety of the dam body.
- Under the anti-seepage membrane or concrete protection surface of the dam, geotextile can be used as a drainage material to prevent the influence of water seepage on the structure.
- It also eliminates the problem of water seepage around the tunnel, reduces the external water pressure to which the lining is subjected, and prevents water seepage around the building.
- Geotextile can provide necessary support and reinforcement when artificially filling the foundation of sports ground.
- In addition, it can also be widely used in soft foundation reinforcement projects of highways, railways, dikes, earth-rock dams, airports, stadiums and other projects.
Geotextile is used for supporting, enhancing stability, filtering and isolating, and its applicable fields include road engineering, water conservancy engineering and airport construction Etc., which can improve construction convenience and engineering stability in various environments.
