Functional applications of filament geotextiles
Release time:
2024-08-05
The performance of filament geotextile on the one hand and the quality of geotextile has a great relationship, on the other hand, also determines the scope of application of geotextile, natural application is very wide, if the performance is not good or weak, the geotextile is narrow, and may not even be used.
Properties of filament geotextiles
1, the nature of the fibre: the fibre twist increases, the filament geotextile sliding resistance increases, the fibre can not be concentrated in one place, the breaking strength is not good. In addition the size of the fibre, the size of the coefficient of friction between the filaments also has a great impact on the breaking strength.
2, fabric structure: filament geotextile plant structure mainly has twill, plain, satin three kinds, which twill, satin due to the high density of the fabric, the number of fibres involved in the force, so its breaking strength is also very high, in contrast, plain filament geotextile breaking strength is much worse.
The function and application of filament geotextile
As mentioned earlier, filament geotextile has many properties, naturally, it has been widely used.
1, in the landfill, sewage treatment plant, filament geotextile mainly play the role of protection, reinforcement, seepage control, that is, to prevent the leakage of harmful liquids on the surrounding environment;
2, in water conservancy projects, filament geotextile mainly plays the role of seepage control, reinforcement, drainage and anti-filtration, on the one hand, to prevent soil erosion, increase the stability of the project, on the other hand, it also improves the strength of the project and prolongs the service life.
3, in the road project, filament geotextile mainly plays the role of drainage and reinforcement. That is, on the one hand, change the performance of geotextile, increase the bearing capacity of the road surface, on the other hand, also extend the service life of the road.

How long can filament geotextiles last?
Generally speaking, filament geotextiles with a certain quality assurance can have a service life of more than 50 years if they are used correctly, and if other factors are excluded, they can be used for up to 100 years under ideal conditions after all. A certain scientist in the Netherlands has woven a filament geotextile with a service life of 200 years, which is, of course, only an example.
According to the relevant research, domestic tests show that filament geotextile buried in the ground use, 10 years after the strength of its decline of no more than 20%, the performance can still maintain more than 80%.
However, assuming that the filament geotextile is exposed to direct sunlight for a long time, then the filament geotextile is generally used for 5 years, the performance of the filament geotextile is almost reduced a lot, and even a tear will be broken.
What is the development prospect of filament geotextile?
In fact, from the 1990s, when people realise the value of filament geotextiles, the use of filament geotextiles in the subsequent infrastructure is increasing, so much so that many engineering and construction is still far from using filament geotextiles, which is precisely the reason why the development of filament geotextile manufacturers is getting better and better.
So for the time being, the development prospects of filament geotextile is still very considerable, because with the progress of society, a lot of facilities still need to expand, in these mining construction projects filament geotextile is certainly indispensable, but no matter how the development of filament geotextile, its quality must be guaranteed.
Filament geotextile can replace the traditional engineering materials and construction methods, making the construction safer, conducive to environmental protection, and more and more durable solution to the basic problems in engineering and construction.
Filament geotextile has good mechanical properties, good water permeability, anticorrosion, anti-aging, isolation, anti-filtration, drainage, protection, stabilisation, reinforcement, etc. It can adapt to uneven grass-roots level, resist the construction of external forces, damage creep is small, and can still maintain its original function under long-term loading.
