The function, use, and characteristics of geotextile
Short fiber needle punched nonwoven geotextiles are divided into polyester, polypropylene, nylon, vinylon, ethylene glycol and other needle punched nonwoven geotextiles according to their raw materials; It is divided into ordinary type and composite type according to structure.
The variety of short fiber needle punched nonwoven geotextile is designed by the production department according to market demand.
The role of geotextile
1: Geotextile Isolation
Using polyester short fiber needle punched geotextile to treat building materials with different physical properties such as particle size, distribution, consistency, and density
Isolate materials such as soil and sand particles, soil and concrete, etc. Ensure that two or more materials are not lost or mixed, and maintain the quality of the material
The overall structure and function of the material enhance the load-bearing capacity of the structure.
2: Geotextile Filtration
When water flows from the fine soil layer to the coarse soil layer, the polyester short fiber needle punched geotextile has good breathability and water permeability, making the water flow
By effectively intercepting soil particles, fine sand, small stones, etc., to maintain the stability of soil and water engineering.
3: Geotextile Drainage
Polyester short fiber needle punched geotextile has good water conductivity, which can form drainage channels inside the soil and reduce the amount of water in the soil structure
Residual liquid and gas discharge.
4: Geotextile Reinforcement
Utilizing polyester short fiber needle punched geotextile to enhance the tensile strength and deformation resistance of soil, enhance the stability of building structures, and improve
Improve soil quality.
5: Geotextile Protection
When water flows through soil, it effectively diffuses, transfers, or decomposes concentrated stress, preventing soil from being damaged by external forces and protecting the soil.
6: Geotextile Puncture prevention
Combined with geomembrane, it becomes a composite waterproof and anti-seepage material, playing a role in preventing puncture.
High tensile strength, good permeability, breathability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, and non insect infestation.
Polyester short fiber needle punched geotextile is a widely used geosynthetic material. Widely used for reinforcement of railway subgrade and highway pavement
Maintenance, sports hall, dam protection, isolation of hydraulic structures, tunnel construction, coastal mudflat, reclamation, environmental protection and other projects.
Characteristics of geotextile
The characteristics of geotextile include: light weight, low cost, corrosion resistance, excellent performance such as filtration, drainage, isolation, and reinforcement.
Geotextiles are widely used in geotechnical engineering such as water conservancy, electricity, mines, highways, railways, etc
1. Geotextiles are filter materials used for soil layer separation.
2. Geotextiles are used as drainage materials for reservoirs and mines, as well as drainage materials for high-rise building foundations;
3. Geotextiles are used as erosion resistant materials for embankments and slope protection.
4. Geotextiles are used as reinforcement materials for railway, highway, and airport runway embankments, as well as for road construction in swampy areas.
5. Geotextiles are used as antifreeze insulation materials.
6. Geotextiles are used as anti cracking materials for asphalt pavement.
