Filament geotextile can replace traditional engineering materials and construction methods, make construction safer and contribute to environmental protection, and solve basic problems in engineering construction more economically, effectively and permanently.
The filament geotextile has good mechanical function, good water permeability, corrosion resistance, anti-aging, isolation, filtration, drainage, protection, stability, reinforcement, etc. It can adapt to the uneven base layer and resist construction external forces. Destruction, creep is small, and the original function can still be maintained under long-term load.
(1) Mass per unit area is 100g/m2 to 800g/m2
(2)1m~6m in roll width, the length as clients' request.
(3)Color: white, black, gray, green
(4)Packing: Packed by PP woven geotextile with paper tube inside.
(1). Strength - The tensile strength in both the longitudinal and transverse directions is higher than that of other needle-punched nonwoven fabrics under the same weight specifications;
(2). UV resistant - has a very high UV resistance;
(3). Extremely high temperature resistance - high temperature resistance up to 230 degrees Celsius, maintaining structural integrity and original physical properties at high temperatures;
(4). Permeability and plane drainage - Geotextile is thick and needle-punched, with good flat drainage and vertical water permeability, and can maintain this performance after many years;
(5). Creep resistance - the creep resistance of geotextiles is superior to other geotextiles, so the long-term effect is good. It is resistant to the erosion of common chemicals in the soil and to corrosion by gasoline, diesel and the like;
(6). Ductility--The geotextile has a good elongation under certain stress, so that it can adapt to the irregular surface of the unevenness;
Technical characteristics of filament geotextile: The thick geotextile can ensure the three-dimensional void ratio of geotextile, which is conducive to the realization of excellent hydraulic performance. The topping strength of geotextiles has great advantages, especially for retaining walls and embankments. The geotextiles have exceeded the national standards and are excellent geotechnical reinforcement materials.
(1) Reinforcement in backfilling of retaining walls, or panels used to anchor retaining walls. Construct a wrapped retaining wall or abutment. The filter layer of the initial upstream dam surface of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill of the retaining wall.
(2) Strengthen the flexible road surface, repair the cracks on the road, and prevent the road surface from reflecting cracks. Segregation of geotextiles between the road, airport, railway track slag and artificial rockfill and foundation.
(3) Increase the stability of gravel slope and reinforced soil to prevent soil erosion and freezing damage of soil during low temperature. The isolation layer between the roadway and the roadbed, or the isolation layer between the roadbed and the soft foundation. Separation, separation and reinforcement between artificial fill, rockfill or material field and foundation, and different frozen soil layers.
(4).Filament nonwoven geotextile is used to landfill.
(5).Filament nonwoven geotextile is used to water conservancy projects.
That is, the use of geotextiles to isolate building materials (such as soil and sand, sand and gravel, soil and concrete) with different physical properties (particle size, distribution, consistency and density). The two or more materials are not lost or mixed, and the overall structure and function of the material are maintained to enhance the load bearing capacity of the structure.
When water flows from the fine-grained soil layer into the coarse-grained soil layer, the water flow is passed through the good gas permeability and water permeability of the needle-punched geotextile. And effectively intercepting soil particles, fine sand, small stones, etc., in order to maintain the stability of water and soil engineering.
Geotextile is a good water-conducting material, which can form a drainage channel in the soil structure to remove excess liquid and gas inside the soil structure.
The geotextile is used to enhance the tensile strength and deformation resistance of the soil, and to enhance the stability of the building structure to improve the soil quality.
Effectively spread, transfer or decompose the concentrated stress to prevent the soil from being damaged by external forces.
The geotextile is combined with other materials (asphalt, plastic film) to form an impervious barrier in the soil layer. (Mainly used for road resurfacing, repair, etc.).
