Warp knitted polyester geotextile

Warp-knitted composite geotextile is a new type of geotechnical material which is made of glass fiber (or synthetic fiber) as a reinforcing material and combined with staple fiber needle-punched non-woven fabric. The biggest feature is that the intersections of the warp and the weft are not bent, and each is in a straight state. Bundle the two together with a binding wire, which can be more evenly synchronized, withstand external forces, distribute stress, and when the applied external force tears the material instantaneously, the yarn will gather along the initial crack and increase the tear strength. When the warp knitting is compounded, the warp knitting bundle is used to repeatedly travel between the weft and the fiber layers of the staple fiber needle-punched geotextile, so that the three are knitted into one. Therefore, the warp-knitted composite geotextile has the characteristics of high tensile strength, low elongation, and the performance of the needle-punched nonwoven fabric. Therefore, the warp-knitted composite geotextile is a kind of reinforced reinforcement, isolation protection, and has a good three-dimensional overall normal and horizontal water and water. Because of its solid matrix and pores, it has a continuous phase and becomes a multi-porous filtering effect. It is a multifunctional geocomposite. It is the world's high-level application of geocomposite substrates.

Warp knitted polyester geotextile product characteristics

High tensile strength, low elongation, uniform longitudinal and transverse deformation, high tear strength, excellent wear resistance, high water permeability and strong filtration.

Warp-knitted composite geotextile main function

Reinforcement, drainage, filtration, protection, isolation

(1) Stabilizing effect of reinforced: It can transfer or distribute local stress acting on the soil to a larger area, and stabilize the deformation and settlement of geotechnical engineering during long-term use.

(2) Isolation: Separate different geotechnical structural materials with geotextiles to form a stable interface, so that they can exert their respective characteristics and overall functions according to design requirements.

(3) Protection: Geotextile has good puncture resistance, so it has good protection performance.

(4) Drainage filtration: Geotextiles allow water to pass through and block the loss of sand particles. The geotextile is placed in a passage of a flowing liquid with suspended particles to block fine mud and allow liquid to pass.

Engineering application of warp-knitted composite geotextile

1. Used for anti-filter protection of retaining walls, road slopes, reservoir dams, earth and rock cofferdams, tunnels and drainage ditch.

2. It is used for drainage between road slopes, roadbeds, backs of mountain roads along the mountain roads, lower railroad tracks, highway subgrades and road surfaces.

3, used in the construction of cofferdams, docks, anti-slope soft soil and block stone isolation, landfill site bottom and anti-seepage layer isolation protection, landfill filter material and garbage separation, asphalt pavement Isolation from the roadbed and road reinforcement.

4. It is used for stratified and reinforced drainage on slopes such as roads and railways, and backfilling the drainage and reinforcement of roadbeds and dams.

5. It is used for the protection of anti-seepage layer in anti-seepage projects such as artificial lakes, rivers and reservoirs.

6. It is used for the isolation of the grassroots and greening planting layers such as landscape greening projects.

7. It is used for drainage and reinforcement on soft foundation to enhance the bearing capacity of the roadbed.
