Polyester non-woven fabric is our common type of non-woven fabric. It has high strength, good high temperature resistance (can be used for a long time in an environment of 150 ℃), aging resistance, UV resistance, high elongation, good stability and air permeability, Corrosion resistance, sound insulation, mothproof, non-toxic and other characteristics. Next, let's take a look at what aspects of polyester non-woven fabrics can be used and what are their corresponding functional characteristics.
Drainage function: It can be used to remove the water seepage around the tunnel and reduce the external water pressure on the lining. The drainage behind the impervious geomembrane in the earth dam or embankment or the lower part of the concrete protective surface, the drainage behind the retaining wall, and the drainage around each building. Exhaust from the body along the plane of the material. Mainly used for vertical or horizontal drainage inside earth dams. Polyester filament non-woven geotextile can form a drainage channel in the soil to collect the moisture in the soil.
Filtration: the filter layer of water wells, relief wells or inclined pressure pipes in water conservancy projects, as well as the isolation layer of geotextiles between roads, airports, railway ballasts and artificial rockfills and the foundation. The filter layer of the drainage system in the backfill of the retaining wall, the filter layer around the drainage concealed pipe or the gravel drainage ditch. The filter layer on the dam surface of the ash storage dam or ore storage dam, the filter layer at the lower part of the embankment, sea temperature or slope protection downstream of the sluice. It is mainly used to produce the filter layer of clay core wall or clay inclined wall of earth-rock dam, and the filter layer of various drainage bodies in earth-rock dam or dike
Non-woven fabric allows water to pass through, and can effectively prevent soil particles from passing through, thereby preventing soil particles from losing and causing soil damage.
Protective effect: prevent surface water from infiltrating into the ground and water migration in the soil, resulting in dry shrinkage or thermal expansion and alkalization of cultivated land. It can temporarily protect the shore or grassland to prevent soil erosion and promote plant growth. It can prevent water surface evaporation or dust in the air from polluting the water surface and road reflection cracks. Prevent the spread of garbage, waste, waste liquid and other harmful substances from polluting groundwater or polluting the environment. It is mainly used to produce geotextiles placed on rivers, rivers, lakes, and coastal slopes to prevent erosion in water. Polyester filament geosynthetic material has protective and anti-scouring effects on soil or water surface.
Isolation effect: the construction of earth-rock dams on the rock foundation or pebble foundation with developed fissures can be used as the isolation between the dam body and the foundation. In soil-rock mixed dams, it can be used to isolate different dam construction materials. It is mainly used for the isolation between railway ballast and subgrade, the isolation between subgrade and weak foundation, and the isolation layer between surface foundations and foundations such as highways, railways, airports, and parking lots. Play their respective characteristics and overall roles as required. Geotextile can separate different soil structures to form a stable interface and separate each layer of structure.
Reinforcement function: It can strengthen the stability of the slope of the piled soil or excavated steep slope, and is used for the reinforcement of the backfill of the retaining wall. It is used to strengthen the weak foundation and at the same time play the role of isolation and filtering. Mainly used in engineering construction, such as highways (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields and other projects. And it can transfer or distribute the local stress on the soil to a larger area, and increase the frictional resistance between the soil and the geotextile. It can stabilize and limit the displacement of civil engineering during long-term use.
Drainage function: It can be used to remove the water seepage around the tunnel and reduce the external water pressure on the lining.
