Non-woven geotextile open classification non-woven fabric
Geotextile (polyester geotextile non-woven geotextile), also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers through needle punching or weaving. The finished product is in the form of cloth and generally has a width of - meters and a length of - meters. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextile has excellent filtration, isolation, reinforcement and protection functions, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance.
Geotextiles are mainly used in the following projects:
Highways (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields and other projects are used to strengthen weak foundations and simultaneously play the role of isolation and filtration. Geotextiles placed on the bank slopes of rivers, rivers, lakes and seas can also prevent running water from making them turbid.
Used as reinforcement in retaining wall backfill or as a panel for anchoring retaining walls. Build wrapped retaining walls or abutments.
Reinforce flexible pavement to repair cracks on the road and prevent reflective cracks on the road.
Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage to the soil at low temperatures.
The isolation layer between the road ballast and the roadbed or the isolation layer between the roadbed and the soft base.
Isolation between different frozen soil layers in artificial fill, rock or material fields and the isolation layer of the foundation. It plays the role of filtering and reinforcement.
The filter layer on the initial upstream dam surface of the ash storage dam or tailings dam is the filter layer of the drainage system in the backfill soil of the retaining wall.
The filter layer around the underground drainage pipe or the gravel drainage ditch.
The filter layer of water wells, pressure relief wells or baroclinic pipes in water conservancy projects.
Geotextile isolation layer between highways, airports, railway tunnels, artificial rockfills, etc. and the foundation.
Vertical or horizontal drainage inside the earth dam is embedded in the soil to dissipate the pore water pressure.
Drainage behind the anti-seepage geomembrane or under the concrete face in earth dams or embankments.
Eliminate water seepage around the tunnel and reduce the external water pressure on the lining and water seepage around the buildings.
Drainage of sports ground foundation on artificial fill foundation.
The past and future development of geotextiles
The application of geotextiles abroad has begun as early as the 1990s. The United States is the country with the largest consumption of geotextiles in the world. At the beginning of the 1990s, its annual consumption was more than 100 million. In recent years, the usage has reached 100 million. Geotextiles in Europe and Japan have also developed rapidly. The annual consumption of geotextiles in Europe in recent years has also been around 100 million, of which spunbond nonwovens account for about % of nonwoven geotextiles. Japan's focus on geotextiles after the mid-1990s There has been significant growth in applications. Among Japanese nonwoven geotextiles, the spunbond method accounts for approximately % of the total nonwoven geotextiles and is mainly spunbonded fabrics.
my country's geotextile started in the early 1990s, but the usage at that time was very small and it was only an experimental application. It was not until the severe floods in 2006 that the government paid attention to the construction department that the application of geotextiles was included in the design specifications and relevant national standards were formulated. Geotextiles did not really receive attention and development. At present, the amount of geotextiles used in my country has exceeded 100 million. Non-woven geotextiles account for about % of the total. my country's civil engineering construction has a huge potential market, and its potential is by no means less than the current consumption of ~100 million in the United States. Experts estimate that my country's geotextiles will still grow at double digits in the coming years, with the fastest growing rate being spunbond filament geotextiles.
During the 15th and 11th Five-Year Plans, my country plans to invest hugely in water conservancy, electricity, transportation, environmental protection, river management and other projects, including water conservancy construction, South-to-North Water Diversion Project, power investment, highway and railway construction, Investments in environmental engineering construction, including ports, airports, garbage disposal, rivers, lakes and sea management, desertification control and other projects amount to trillions of yuan. China will have more infrastructure projects to be built in the next year or longer, and the demand for geotextiles will also increase. China will become the world's largest marketing market for geosynthetic materials.
