PP Spunbonded Nonwoven Geotextile Fabric For Dirt Roads
Basic Info
Model No.: Geotextile
Product Description
Polypropylene nonwoven fabric has been widely applied to solve the roadbed subsidence and the subject of the mud pumping, drainage system for earth and rockfill dam, underground pipes, soft ground reinforcement, all kinds of bank slope protection filter layer of shoulder pads and other projects.Therefore, the development of nonwoven Geotextile is very fast, and has become the main component of the geotextile.The non-woven geotextile has a large elongation rate and can adapt to the larger deformation, which can be made into the suitable size of pores, and has a better seepage power in both horizontal and vertical direction.
Four basic functions are defined for the geotextile:
Filtration
Filtration functions to restrict the migration of fine soil particles from a soil mass while remaining permeable to water movement greater than, or at least equivalent to the permeability of the protected soil.
Drainage
Water is conveyed along the path of the geotextile due to its construction, and then to an outlet. Water may be vertically or horizontally conveyed. Drainage is related to the role of filtration, and is a function of the permeability of a geotextile and its pore opening size or porometry.
Separation
Separation is the function which prevents two distinct soils of different materials from intermixing. The key factors for a geotextile to satisfy this function are porometry, toughness and strength.
Reinforcement
This function involves the stabilization of a soil mass by provision of tensile strength to the soil-fabric system.
Geotextile selection can be expressed as a relationship between these 4 basic functions and the properties required by the design engineer in order to satisfy certain criteria, which would relate to a specific application.
Product description:
Geotextile is also known as weaving geomaterial geotextiles fabric is a kind of geomaterial with good permeability which is acupunctured or knitted. Geotextile can be divided into woven and non-woven geotextile, short and long woven geotextile, Polyester composite geotextile, intertexture geotextiles.
Product features:
This product has the function of filtering, isolation, strengthening, high tensile strength, good permeability, high temperature resistance, freezing resistance, ageing resistance and corrosion resistance.
