Product Introduction
Filament needle punched geotextile
The filament geotextile is a polyester filament needle-punched non-woven geotextile, which does not contain chemical additives and is not heat treated. It is an environmentally friendly building material.
Characteristics
It 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.
Filament geotextile characteristics:
1. Strength - under the same weight specifications, the tensile strength is higher than other needle-punched nonwovens;
UV-resistant light - extremely high UV resistance;
2. Extremely high temperature resistance - high temperature resistance up to 230 ° C, maintaining structural integrity and original physical properties at high temperatures;
3. Permeability and flat drainage - Geotextiles are thicker and needle-punched, with good flat drainage and vertical water permeability, and can maintain this performance after many years;
4. Creep resistance - geotextile creep resistance is superior to other geotextiles, so it has good long-term performance. It is resistant to the erosion of common chemicals in the soil and to corrosion by gasoline, diesel and the like;
5. Extensibility - the geotextile has a good elongation under certain stresses, 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.

Production
Application
(1) Reinforcement in backfilling of retaining walls, or panels used to anchor retaining walls. Construct a wrapped retaining wall or abutment.
(2) Strengthen the flexible road surface, repair the cracks on the road, and prevent the road surface from reflecting cracks.
(3) Increase the stability of gravel slope and reinforced soil to prevent soil erosion and freezing damage of soil during low temperature.
(4) The isolation layer between the roadway and the roadbed, or the isolation layer between the roadbed and the soft foundation.
(5) Separation, anti-filtration and reinforcement between artificial fill, rockfill or material field and foundation, separation between different frozen soil layers.
(6) 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.
(7) The drainage layer around the drainage dark pipe or the gravel drainage dark groove.
