Hongyue filament geotextile

Characteristics

• Good Mechanical Properties
  • High Strength: Filament geotextile has relatively high tensile, tear - resistant, bursting - resistant and puncture - resistant strength. Under the same grammage specification, the tensile strength in all directions is higher than that of other needle - punched non - woven fabrics. It can effectively enhance the stability and bearing capacity of the soil. For example, in road engineering, it can improve the strength of the roadbed and prevent the road surface from cracking and collapsing due to uneven stress.
  • Good Ductility: It has a certain elongation rate and can deform to a certain extent without breaking when subjected to force. It can adapt to the uneven settlement and deformation of the foundation, evenly distribute the load and maintain the integrity of the engineering structure.
• Excellent Hydraulic PropertiesGood Chemical Stability: It has good corrosion resistance to chemical substances such as acids, alkalis and salts in the soil and pollutants from the petroleum and chemical industries. It can maintain stable performance in harsh chemical environments for a long time and can be applied in places such as landfills and chemical sewage ponds.
  • Strong Drainage Capacity: Filament geotextile has small and interconnected pores, which endows it with vertical and horizontal drainage capabilities. It can allow water to gather and drain, effectively reducing the pore water pressure. It can be used in the drainage systems of earth dams, roadbeds and other projects to drain the accumulated water in the foundation and enhance the stability of the foundation.
  • Good Filtration Performance: It can prevent soil particles from passing through while allowing water to permeate freely, avoiding the loss of soil particles and maintaining the stability of the soil structure. It is often used for the filter - protection of dam slopes, canals and other parts in water conservancy engineering.
• Outstanding Anti - aging Performance: With the addition of anti - aging agents and other additives, it has strong anti - ultraviolet, antioxidant and weather - resistance capabilities. When exposed to outdoor environments for a long time, such as in open - air water conservancy and road projects, it can withstand direct sunlight, wind and rain erosion and has a long service life.
• Large Friction Coefficient: It has a large friction coefficient with contact materials such as soil. It is not easy to slip during construction and can ensure the stability of laying on slopes. It is often used in slope protection and retaining wall engineering.
• High Construction Convenience: It is light - weight, easy to carry and lay. It can be cut and spliced according to engineering needs, with high construction efficiency and can reduce construction costs and labor intensity.

Applications

• Water Conservancy Engineering
  • Dam Protection: It is used on the upstream and downstream surfaces of dams and can play the roles of filtration - protection, drainage and reinforcement. It prevents the dam soil from being scoured by water flow and enhances the anti - seepage and stability of the dam. For example, it is widely used in the reinforcement project of the Yangtze River embankment.
  • Canal Lining: It is laid at the bottom and on both sides of the canal as a filtration - protection and isolation layer to prevent water in the canal from leaking and at the same time avoid soil particles from entering the canal and affecting the water flow. It can improve the water - conveyance efficiency and service life of the canal.
  • Reservoir Construction: It is laid on the dam body and at the bottom of the reservoir, which helps with drainage and prevents the dam body from sliding and ensures the safe operation of the reservoir.
• Transportation Engineering
  • Highway Engineering: It can be used to reinforce soft foundations, improve the bearing capacity of the foundation and reduce the settlement and deformation of the roadbed. As an isolation layer, it separates different soil layers and prevents the mixing of the upper - layer pavement materials and the lower - layer roadbed soil. It can also play the roles of drainage and preventing reflective cracks and extend the service life of the highway. It is often used in the construction and renovation of expressways and first - class highways.
  • Railway Engineering: In railway embankments, it is used as a reinforcement material to enhance the overall stability of the embankment and prevent the embankment from sliding and collapsing under train loads and natural factors. It can also be used for the isolation and drainage of railway ballasts to improve the working conditions of the ballast and ensure the safe operation of the railway.
• Environmental Protection Engineering
  • Landfill: It is laid at the bottom and around the landfill as a seepage - prevention and isolation layer to prevent landfill leachate from leaking into groundwater and polluting the soil and groundwater environment. It can also be used for the cover of landfills to reduce rainwater infiltration, reduce the production of leachate and at the same time suppress the emission of garbage odor.
  • Sewage Treatment Pond: It is used on the inner wall and at the bottom of the sewage treatment pond to play the roles of seepage - prevention and filtration - protection and ensure that the sewage does not leak during the treatment process and avoid polluting the surrounding environment.
• Mining Engineering
  • Tailings Pond: It is laid on the dam body and at the bottom of the tailings pond to prevent harmful substances in the tailings from leaking into the surrounding environment with the leachate and protect the surrounding soil, water and ecological environment. At the same time, it can enhance the stability of the dam body and prevent accidents such as dam - body failure.
• Agricultural Engineering
  • Irrigation Canal: Similar to its application in the canals of water conservancy engineering, it can prevent canal leakage, improve water - use efficiency and ensure the normal progress of farmland irrigation.
  • Farmland Protection: It is used for the slope protection of farmland to prevent soil erosion and protect the soil resources of farmland. It can also be used as a covering material to inhibit weed growth, maintain soil moisture and promote crop growth.
