Product

Fiberglass geogrid composite geotextile is glass fiber as reinforcing material, formed by and short fiber needle punched nonwoven composite.
Glass fiber composite geotechnical cloth is different from general machine weaving. The biggest feature is the warpweft intersection points does not bend, each in a flat state. With the binding line, the two can be tightly tied together, which can be fully and evenly synchronous, bear the external force, distribute the stress, and when the applied force is applied to the instantaneous of the material, the yarn can be held along the initial crack to increase the tear strength.
Warp knitting composite, namely the use of warp thread bundles in the weft yarn and staple fiber needle punched geotextile fiber layer repeatedly through the three knitting into one. So the composite geotextile has high tensile strength, low elongation characteristics, but also has the characteristics of nonwovens. Warp knitted composite geotechnical cloth is therefore a can be used for reinforcement, isolation and protection and has three-dimensional integral method to and levels were a good poly water, different water effect. Because of its solid matrix and porosity are continuous phase, become porous filtering effect, is a kind of multifunctional composite materials.
(two) product characteristics
High tensile strength, low elongation, uniform longitudinal and transverse deformation, high tear strength, good abrasion resistance, high water permeability and strong anti filter performance.
(three) the main function of warp knitted composite geotextile.
Reinforcement, drainage, anti filtration, protection, isolation
(1) reinforcement effect: can make the role of local stress in the soil transfer or distribution to a larger area, the stability of geotechnical engineering in the long time to use the process of deformation, settlement.
(2) isolating function: with geotextile to different soil structure isolation material forming stable interface, in accordance with design requirements to play their respective characteristics and the overall effect.
(3) the protection function: the earthwork cloth has the very good anti puncture ability, therefore has the very good protection performance.
(4) drainage and filtration effect: geotextile can let the water and prevent the loss of sand particles, geotextile placed horizontally in a channel of suspended particles in the liquid flowing in prevent the fine clay particle and allow liquid to pass through.
(four) engineering application of warp knitted composite geotextiles
1, used in retaining wall, road slope, reservoir dam, earth rock cofferdam, tunnel, drainage ditch anti filter protection.
2, used in road slope, embankment, along the mountain road back to the mountain on the back of the wall, railway ballast layer, highway subgrade and pavement drainage.
3, used in construction cofferdam, docks, anti slope embankment in soft soil and stone isolation, landfill field bottom and impermeable layer of isolation and protection, isolation between the filter and garbage landfill, isolation and pavement of asphalt pavement and roadbed enhancement.
4, used in highway and railway slope layered reinforced backfill subgrade drainage, drainage and embankment reinforcement.
5, used in the artificial lake, river, reservoir and other impervious works, such as the protection of the impermeable layer.
6, used in the landscape greening projects and green grass planting layer of isolation.
7, used in the soft foundation drainage, reinforcement of the subgrade bearing capacity
