Instruction of Non-woven Geotextile for Railway Construction:
Geotextile is a non-woven product manufactured by combinining synthetic short yarns mechanically by using needling method. Non-woven geotextile has no woof and warp. Strength is achieved by combining yarns and applying thermal process. Geotextile felt is a permeable textile product which can be used with basic elements or with any material related with soil, running ground or geotechnic engineering.
Usuage Area of Non-woven Geotextile for Railway Construction:
Used in motorways, sport facilities, tunnels and underground facilities, art buildings, underground, agricultural areas, garden terraces, airports, mining fields, railways, solid waste storage areas, irrigation channels and reservoirs, shore protection and isolation areas; as a reinforcement against cracks between insulation layers; as a separator between waterproofing and thermal insulation layers; to protect insulation; to drain excess water; to prevent drainage pipes from plugging by wrapping them around; to avoid sinking and in many other applications.

Advantages of Non-woven Geotextile for Railway Construction:
Thanks to thermal process, more strength and less elongation is achieved with the same weight.
Requires smaller storage area.
Can be manufactured up to a width of 6 meters, leading to less loss of material.
Both white and tinted varieties of ge0textile are manufactured from 100% pure yarn. No recycled material is used.
Products can be manufactured with surface weight ranging from 50 gr/m2 to 1000 gr/m2.
Application of Non-woven Geotextile for Railway Construction:
- in liquid bituminous insulation applications, it is used as a reinforcement between layers and avoids cracks.
- it prevents cracks found on the surface from moving onto insulation surface.
- it protects bituminous membrane or geomembrane applications in foundations.
- it is used as a separator between waterproofing and thermal insulation layers.
- it is used as a separator between thermal insulation and protection layers.
- It is wrapped around drainage pipes in foundations and it is used as a filter layer in terrace gardens.
- It is used in applications designed to withdraw pressure under road coatings.
- Q: Are geotextiles suitable for use in waste containment systems?
- Yes, geotextiles are suitable for use in waste containment systems. They are commonly used as liners or covers in landfills and other waste management facilities to prevent the migration of contaminants and control leachate. Geotextiles provide filtration, separation, and reinforcement properties that enhance the overall performance and longevity of waste containment systems.
- Q: What are the specifications for geotextiles in railway projects?
- The specifications for geotextiles in railway projects generally include requirements for strength, durability, permeability, and filtration. These geotextiles should have sufficient tensile strength to withstand the dynamic loads imposed by trains and maintain their integrity over time. They should also be resistant to degradation caused by UV exposure, chemical exposure, and biological factors. The permeability of geotextiles is crucial to ensure proper drainage and prevent water accumulation, which can lead to instability. Additionally, the geotextiles should possess excellent filtration properties to prevent the migration of fine particles and maintain the stability of the railway subgrade.
- Q: Sng400-2.5gb / t-1998 geotextile is what the specifications
- SNG400-2.5 refers to the national standard polyester staple acupuncture non-woven geotextile 400g / ㎡, width 2.5m. The standard code for the GB / T-1998 staple fiber nonwoven geotextile is generally the SNG / (1) (2) / (3) - (4) / (5). (1) that the use of raw materials fiber code: PET-polyester, PP-polypropylene, PA-nylon, PV-vinylon, PE-Ethylene (conventional polyester are generally vacant omitted code) (2) that polyester staple fiber non-woven Geotextile per unit area weight. (3) that the composite products in the polyester staple fiber non-woven geotextile weight per unit area, non-composite product vacancies. (4) width, expressed in meters (5) production department number: can express the product more specific characteristics, functions, varieties, sequences, etc., the general vacancy. For example, 2.5m wide 400g / ㎡ polyester staple fiber non-woven geotextile representation of the method can be SNG / PET400-2.5, can also be expressed as SNG400-2.5
- Q: Differences between staple acupuncture nonwoven geotextile and filament spunbonded nonwoven geotextile
- Appearance of different shapes: staple acupuncture non-woven geotextile in the appearance of the surface of the fiber is shorter, and filament spunbond acupuncture non-woven geotextile surface fiber longer. Different materials: staple acupuncture non-woven geotextile with PET polyester staple fiber acupuncture, and filament spunbond acupuncture non-woven geotextile made of polyester chips. Production equipment and different technology: staple acupuncture non-woven geotextile is the polyester staple fiber through the mixing - clutter - comb - shop - acupuncture, and filament spunbond acupuncture non-woven geotextile is the polyester Sliced hot melt - spinning - carding - shop - acupuncture. Implementation of different standards: staple acupuncture non-woven geotextile implementation of GB / T-2008 standards, and filament spunbond acupuncture non-woven geotextile implementation of GB / T-2008 standard. The same specifications of filament spunbonded acupuncture non-woven geotextile quality is better than staple acupuncture non-woven geotextile. Price: the same specifications of polyester staple acupuncture non-woven geotextile price is lower than filament spunbond acupuncture non-woven geotextile.
- Q: Can geotextiles be used in wastewater treatment applications?
- Yes, geotextiles can be used in wastewater treatment applications. They are commonly used as a filtration and separation medium in various stages of the treatment process, such as in sedimentation tanks, sludge dewatering, and effluent filtration. Geotextiles help to retain solids, prevent clogging, and enhance the overall efficiency of wastewater treatment systems.
- Q: Where the detection of geotextiles more authoritative
- To the authority must find the authority of the body, the international authority was undoubtedly SGS, geotextile common test such as area weight, tear strength, puncture strength.
- Q: Waterproof geotextile how much money per square meter
- This material has a lot of different quality, there are many different requirements, the price from dozens of pieces to more than 100 pieces between.
- Q: How do geotextiles help in preventing piping failure?
- Geotextiles help in preventing piping failure by acting as a filter layer, allowing water to pass through while retaining soil particles. This helps in stabilizing the soil and preventing erosion, which is a major cause of piping failure. Additionally, geotextiles provide reinforcement and improve the overall strength of the soil, reducing the likelihood of pipe movement and failure.
- Q: How do geotextiles help with reinforcement of geogrid reinforced soil slopes?
- Geotextiles help with the reinforcement of geogrid reinforced soil slopes by providing additional strength and stability to the system. They act as a separator between the soil and the geogrid, preventing soil particles from infiltrating the geogrid and reducing its effectiveness. The geotextiles also distribute the load evenly across the geogrid, improving its load-bearing capacity and reducing the potential for localized failures. Additionally, geotextiles can enhance the overall drainage and filtration properties of the slope, minimizing the risk of water accumulation and soil erosion.
