Applications of Filament Non-woven Geotextile for Railway Construction:
1) Filtration :
The filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.
2) Separation :
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different granule pathway from the groundsill or other buildings.
3) Adding muscle :
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earth body stability.
4) Protection :
It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
Features of Filament Non-woven Geotextile for Railway Construction:
1) Staple fibers needle punched non woven geotextile
The geotextile is made of polypropylene staple fibers on cross-laying equipment and needle punched equipment. It owns the advantages of acid and alkali resistance, erosion resistance, aging resistance, large strength, stable size, good filtrability etc.
2) Filament non woven geotextile
Filament geotextile has features as follows: High strength, good capacity of elongation and high biology tolerance, alkali tolerance, acidity tolerance, weather resistance good filtration and fine drainage capacity etc. Also it is of low cost, easy in construction and use effects.
