    Title:
    Characteristics and Applications of geotextiles 
    Characteristics of a geotextile
    The geotextile is a new type building materials, raw materials are polypropylene, polyester, acrylic, nylon and other polymers, synthetic fibers. Due to the good performance of geotextiles, landfill, artificial lakes, channels more widely. In accordance with the manufacturing methods are divided into: There are two types of spinning geotextiles and nonwoven geotextile.
    Woven geotextile geotextiles ---- that is, the warp and weft interwoven. Its thickness is thinner, the general thickness of 0.2mm, 0.4mm, 0.7mm. Its tensile strength is strong, about 250kg/cm2 permeability coefficient of about 6.1 * 10-4cm / s, and the texture stability, good durability, non-woven geotextile ---- that is, irregular arrangement of the fibers by bonding needle made of mesh material. Commonly used is a needle-type non-woven geotextile. Such geotextile has a strong compressibility, porosity, hydraulic conductivity better performance, better than the woven geotextile.

    Does not contain chemical additives, prop without heat treatment, is environmentally friendly building materials. It can replace traditional engineering materials and construction methods, construction is more secure, and contribute to environmental protection, more economic, effective and lasting solution to the basic problems in construction projects.

    Has good mechanical properties, permeability, and anti-corrosion, anti-aging.

    Isolation, filtration, drainage, protection, solid, strengthening functions. Able to adapt to uneven grass-roots level, able to resist the construction of external damage, creep, long-term loading to maintain the original function. The overall continuity, light weight and easy construction.


    According to the fiber length can be divided into short fiber needle-punched geotextile and polyester filament geotextile

    Short fiber needle-punched geotextile
    Short fiber needle-punched geotextile is made of polyester or polypropylene staple fiber carding or network acupuncture consolidation.
    The product has excellent water permeability, filtration, durability, can be widely used in railways, highways, sports hall, dams, hydraulic construction, then the hole, coastal beach, land reclamation, environmental protection and other projects.
    Function:
    (1) the use of the the geotextile good air permeability and water permeability, so that the flow of water through interception of sand loss.
    2 geotextile hydraulic conductivity performance, it can form a soil internal drainage channels, and efflux of the excess liquid and gas within the soil structure.
    The use of geotextile reinforced soil tensile strength and resistance to deformation, and enhance the stability of the building structure in order to improve the quality of the soil.
    4 will focus on stress proliferation, transfer, or decomposition, to prevent the soil by external force destruction.
    (5) to prevent confounding between the upper and lower layers of sand, soil and concrete.
    6 mesh is not easy to plug the strain and movement - amorphous reticular formation of fibrous tissue.
    High permeability - in the soil water pressure, can still maintain good water permeability
    Corrosion - chemical fiber as raw materials such as polypropylene or polyester, acid and alkali, non-corrosive, not moth-eaten, antioxidant
    Construction is simple - the light weight, easy to use, simple construction

    Polyester filament geotextile performance characteristics:
    Polyester filament geotextile is polyester approach made directly by spinning acupuncture consolidation, product specifications from 80-800g / m 2 optional, it is a geotechnical and civil engineering applications of geosynthetics is made of polyester filament yarn to form a network and consolidation of its fibers are arranged in three-dimensional structure. In addition to good mechanical properties, also has a good vertical and horizontal drainage performance and a good extension of performance and high resistance to biological, acid and alkali resistance, aging chemical stability. Also has a wide aperture range, tortuous pore size distribution, excellent penetration resistance and filtration

    Geotextile-related parameters
    The company produces geotextiles are mainly high-quality polyester staple fiber-based (fiber-9dtox length 50-76mm) can also be based on user requirements polypropylene, cotton lun, polyvinyl alcohol fiber or mixed fiber needle-punched geotextile.
    Second, the geotextile functions, the role of
    1. Isolation
    Namely the use of geotextiles with different physical properties (grain trails, distribution, consistency, density, etc.), building materials (such as soil and sand, sand and gravel, soil and concrete, etc.) in isolation. The two multiple between loss of material, not mixed, to maintain the overall structure and function of materials, structures, load bearing capacity to strengthen
    2 Filtration
    When water from the layer of fine material into the layer of coarse material, the use of needle-punched geotextile good air permeability and water permeability so that water flows through the closure of soil particles, sand, small stone, in order to maintain the stability of the Soil and Water Engineering . (Figure 2).
    3. Drainage
    The needle-punched geotextile hydraulic conductivity material, it can form a drainage channel within the soil, the efflux of excess liquids and gases in the soil structure. (Figure 3)
    4 on reinforced
    The needle-punched geotextile reinforced soil tensile strength and resistance to deformation, increase the stability of the building structure, to improve the quality of the soil. (Figure 4)
    5 Protective
    The proliferation of concentrated stress, transfer, or decomposition, to prevent the diagram by external force destruction. (Figure 5)
    6 Closed
    The needle-punched geotextile, and other materials (asphalt or plastic film) with soil to form a watertight compartment. (For road resurfacing to repair, etc.)
     
     
    Three areas of application of the geotextile
    Hydraulic Engineering: seawalls, river bank, Hudi standard works; reservoir reinforcement project; reclamation project; flood control.

    Road and rail airport project: Soft Foundation Treatment; slope protection; road anti-reflective cracking structural layer; drainage system; greenbelt.

    Electrical engineering: Nuclear power plant infrastructure projects; thermal power ash dam projects; hydropower project.

    Port waterway engineering: Port

    Geomembrane performance purposes:

    The product has a good filtration, drainage, isolate the role reinforced the role of protective effect.

    Can be used in railways, highways, sports hall, dams, water conservancy construction, tunnel, coastal beach, Wai Ken, environmental protection, power plants, airports and other projects.

       
    Functions:
    ◆ the use of geotextile permeability and permeability, the flow of water through the interception of sand loss;
    ◆ geotextile has a good performance of the hydraulic conductivity, it can form a soil internal drainage channel, the efflux of excess liquids and gases within the soil structure;
    ◆ geotextile reinforced soil tensile strength and deformation resistance, enhanced stability of the building structure, to improve the quality of the soil;
    ◆ the effective stress concentration diffusion, transfer, or decomposition, to prevent the soil is destruction by external force;
    ◆ to prevent the upper and lower gravel, soil and concrete mix;
    ◆ mesh difficult to plug the amorphous reticular formation of fibrous tissue strain and movement
    ◆ high water permeability in the soil water under pressure and still maintain good water permeability;
    ◆ corrosion-resistant chemical fiber as raw materials such as polypropylene or polyester, acid, non-corrosive, not moth-eaten, antioxidant;
    ◆ the advantages of light weight, simple construction, easy to use, and shorten the duration, enhance economic efficiency, extend the project to use weeks
