Function:
1: Isolation
Use polyester short fiber acupuncture geotextile to isolate building materials (such as soil and sand, soil and concrete, etc.) with different physical properties (particle size, distribution, consistency, density, etc.). Make two or more kinds of materials do not lose, do not mix, maintain the overall structure and function of the material, so that the bearing capacity of the structure is strengthened.
2: Filtration (anti -filtration)
When the water flows into the coarse soil layer from the fine soil layer,Use the good air permeability and water permeability of Polyester short fiber needle punched geotextile let the water flow through,. and effectively intercept soil particles, fine sand, small stone, etc., so as to maintain the stability of soil and water engineering.
3: Drainage
Polyester short fiber needle punched geotextile has good water conductivity. It can form a drainage channel inside the soil to discharge the excess liquid and gas in the soil.
4: Reinforcement
Polyester staple fiber needled geotextile is used to enhance the tensile strength and deformation resistance of soil, enhance the stability of building structure, and improve the quality of soil.
5: Protection
When the water flows to the soil, it can effectively diffuse, transfer or decompose the concentrated stress, prevent the soil from being damaged by external forces, and protect the soil.
6: Puncture prevention
Combined with geomembrane, it becomes a composite waterproof and impermeable material to prevent puncture.
High tensile strength, good permeability, breathable performance, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, no moth.
Polyester staple fiber needled geotextile is a widely used geosynthetic material. It is widely used in railway subgrade reinforcement, highway pavement maintenance, sports hall, dam protection, hydraulic building isolation, tunnel, coastal beach, reclamation, environmental protection and other projects.
Characteristics:
Light weight, low cost, corrosion resistance, with filtration, drainage, isolation, enhancement and other excellent performance.
Application:
(1) for reinforcement in the backfilling of the retaining wall, or for the panel of anchoring the retaining wall. Construct parcel retaining walls or abutments.
(2) Reinforce the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.
(3) Increase the stability of gravel slope and reinforced soil, prevent soil erosion and soil freezing damage at low temperature.
(4) the isolation layer between ballast and subgrade, or the isolation layer between subgrade and soft foundation.
(5) Isolation layer between artificial fill, rockfill or material field and foundation, and isolation between different permafrost layers. Filtration and reinforcement.
(6) the filter layer of the initial upstream dam face of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill soil of the retaining wall.
(7) the filter layer around the drainage dark pipe or the gravel drainage dark ditch.
(8) The filter layer of water Wells, relief Wells or baroclinic pipes in hydraulic engineering.
(9) the isolation layer of geotextiles between roads, airports, railway roads and artificial rockfill and the foundation.
(10) The internal vertical or horizontal drainage of the earth dam, buried in the soil to dissipate the void water pressure.
(11) Drainage behind the impermeable geomembrane or under the concrete protective surface in the earth dam or embankment.
(12) Eliminate water seepage around the tunnel, reduce the external water pressure borne by the lining and water seepage around the buildings.
(13) Drainage of sports ground foundation by artificial land reclamation.
(14) roads (including temporary roads) railways, embankments, earth and rock DAMS, airports, sports fields and other projects used to strengthen the weak foundation.
