Conventional classification of geotextiles and their various characteristics

1. Needle-punched non-woven geotextile, the specifications are arbitrarily selected between 100g/m2-1000g/m2, the main raw material is polyester staple fiber or polypropylene staple fiber, made by acupuncture method, the main uses are: river, sea, lake and river Slope protection of embankments, land reclamation, docks, ship locks, flood control and emergency rescue projects are effective ways to conserve soil and water and prevent piping through backfiltration.

2. Acupuncture non-woven fabric and PE film composite geotextile, the specifications are one fabric and one film, two fabrics and one film, the maximum width is 4.2 meters. The main raw material is polyester staple fiber needle-punched non-woven fabric, and the PE film is made by compounding , The main purpose is anti-seepage, suitable for railways, highways, tunnels, subways, airports and other projects.

3. Non-woven and woven composite geotextiles, varieties of non-woven and polypropylene filament woven composite, non-woven and plastic woven composite, suitable for basic engineering facilities for foundation reinforcement and adjustment of permeability coefficient.

Features:

Light weight, low cost, corrosion resistance, excellent performance such as anti-filtration, drainage, isolation and reinforcement.

Use:

Widely used in water conservancy, electric power, mine, highway and railway and other geotechnical engineering:

1. Filter material for soil layer separation;

2. Drainage materials for mineral processing in reservoirs and mines, and drainage materials for high-rise building foundations;

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

Geotextile Features

1. High strength, due to the use of plastic fibers, it can maintain sufficient strength and elongation in wet and dry conditions.

2. Corrosion resistance, long-term corrosion resistance in soil and water with different pH.

3. Good water permeability There are gaps between fibers, so it has good water permeability.

4. Good anti-microbial properties, no damage to microorganisms and moths.

5. The construction is convenient.
