woven geotextile 200g m2, non woven needle punched polyester geotextile
Introduction
Non woven geotextile is a kind of new building materials,the raw material is polyester, polypropylene, acrylic, nylon and other synthetic polymers. According to the manufacturing methods are divided into: woven geotextile and non-woven geotextile two types.General engineering mainly use the non-woven geotextile .
Geotextile is impervious, filter, drainage, isolation, reinforcement and protection, sealing and other functions, it compared with the conventional masonry and concrete materials anti-seepage effect, low investment, simple construction technology, short time limit, good anti-seepage effect, channel high effective utilization coefficient, etc
Characteristics
1. High strength, due to the use of plastic fiber, in the wet state can keep sufficient strength and elongation.
2. Corrosion resistance, can in different ph value of soil and water corrosion for long.
3. Good permeability Have a gap between the fibre, therefore has the good porous.
4. The microbial resistance is good On microbe, bug eat by moth.
5. Construction is convenient, because the material is qualitative light, soft, transporting, laying, construction is
convenient.
6. Complete specifications, width can be up to 9 m.Is the present domestic the most wide products, mass per unit
area: 100-1000 g /sq.m.
Role Play
1. Isolation
Use of polyester staple fiber nonwoven fabric with different physical properties (particle size, distribution, consistency and density, etc.) of the building materials (such as soil and sand, soil and concrete, etc.) in isolation.Make no loss between two or more materials, not mixed, maintains the whole structure and function of material, to reinforce structure load bearing capacity.
2. Filteration
When water flows into coarse material composed of fine soil soil layer, the use of polyester staple fiber geotextile acupuncture good air permeability and water permeability, make the water flow through, and effectively current-carrying soil particles, sand, small stones, etc., to maintain the stability of soil and water conservation project.
3. Drainage
Polyester staple fiber geotextile acupuncture has good conductivity performance, it can be formed within soil drainage channel, excess liquid and gas discharge of the soil structure.
4. Reinforced
Use of polyester staple fiber nonwoven fabric enhanced the tensile strength and resistance to deformation ability of soil, to improve the stability of the building structure, to improve soil quality.
5. Protective
Water to soil erosion, effective will be concentrated stress diffusion, transfer or decomposition, prevent soil by external force damage, the protection of the soil.
6. Puncture proof
Combined with geomembrane as composite waterproof seepage control material, have the effect of anti puncture.
High tensile strength, good permeability, permeability, high temperature resistance, freezing resistance, aging-resistance, corrosion resistance, no bug eat by moth. Polyester staple fiber geotextile acupuncture is a widely used geosynthetic materials.Widely used in railway subgrade reinforcement, highway pavement maintenance, sports hall, of the levee protection, hydraulic structures of isolation, hence hole, tidal flats, reclamation, environmental protection and other projects.
Application Field
(1) As a retaining wall reinforcement in the backfill, or used to anchor retaining wall panel. Build a package type retaining wall or abutment.
(2) The flexible pavement reinforcement, repair the crack in the road, to prevent the reflection cracks.
(3) Increase the stability of rock slope and reinforced, prevent water loss and soil erosion and soil temperatures when the frost damage.
(4) Then ballast and subgrade, the isolation layer between the isolation layer or between subgrade and soft soil foundation.
(5) Artificial filled soil, pile of stone or isolation layer of the material field and foundation, the isolation between
woven geotextile 200g m2, non woven needle punched polyester geotextiledifferent permafrost. Filter and reinforcement effect.
(6) Store ash dam or the early stages of the tailings dam upstream filter layer on the surface of the dam, retaining wall drainage system in the backfill soil filter layer.
(7) Drainage drainage tubes or gravel around the perimeter of the drainage culvert filter layer.
(8) Relief Wells, water Wells in water conservancy engineering or baroclinic tube filter layer.
(9) Roads, airports, railway road can be compared and artificial stone pile and foundation between the isolationlayer of geotextiles.
(10) Inside the earth dam vertical or horizontal drainage, soil into the void water pressure in the lift.
(11) Eearth dam or dam anti-seepage geomembrane in the back or a drain at the bottom of the concrete surface protection.
