At present, with the continuous change of production level, filament geotextiles have gradually replaced traditional engineering materials and construction methods. The construction is simple and convenient, saving a lot of manpower and material resources, and protecting the environment. In other words, geotextiles can enable us to solve the basic problems in the past construction process more economically, conveniently and durablely. The emergence of filament geotextiles is an important manifestation of productivity improvement. Geotextiles have good mechanical properties, good water permeability, and corrosion resistance. They have the functions of spacing, reverse filtration, drainage, protection, stabilization, and reinforcement. ,It can adapt to uneven bases, can resist damage from external forces during construction, has small creep, and can still maintain its original functions under long-term loads.

Filament geotextiles have the following characteristics:

1. Strength - Under the same specifications, the tensile strength of geotextiles is higher than that of other ordinary geotextiles.

2. The ability to resist ultraviolet rays is better, which also means that it has a longer service life.

3. High temperature resistance. At a high temperature of more than 200 degrees, the geotextile will still maintain the integrity of the structure and the original physical properties.

4. The permeability and drainage are relatively good.

5. Corrosion resistance. Geotextiles are resistant to corrosion by common chemicals in the soil, as well as diesel and gasoline.

6. The filament geotextile is relatively thick, which can realize the three-dimensional porosity of the geotextile, which is conducive to the realization of excellent hydraulic performance. The bursting strength of geotextiles has great advantages, and it is more suitable for retaining walls and embankment reinforcement. The indicators of geotextiles all exceed the standard, and it is an excellent geotechnical reinforcement material.

Use:

It is widely used in geotechnical engineering such as water conservancy, electric power, mine, road and railway:

l. Filter material for soil layer separation;

2. Drainage materials for reservoirs and mine beneficiation, and drainage materials for high-rise building foundations;

3. Anti-scouring materials for river dams and slope protection;

4. Reinforcement materials for roadbeds of railways, highways, and airport runways, and reinforcement materials for road repairs in swampy areas;

5. Anti-frost and anti-freeze insulation materials;

6. Anti-cracking material for asphalt pavement.
