Geotextile is an engineering material widely used in civil engineering, ecological restoration and environmental protection. It is usually made of synthetic fibers and has good water permeability, strength and durability. The following is a detailed introduction to the definition, classification, characteristics, application and construction precautions of geotextile.
Geotextile is based on synthetic fibers, has strong water permeability and high tensile strength, can isolate, reinforce and filter soil, and is widely used in road reinforcement, dam anti-seepage, landfill isolation and other scenarios. This lightweight and durable material can reduce soil erosion by 60%, extend the life of the project, and become the core solution for stability and environmental protection in civil engineering.
Classification and Features of 500 gsm Black short fiber polypropylene nonwoven Geotextile
Geotextiles are mainly divided into three categories according to production process, composite form and fiber type: non-woven geotextiles (such as staple needle punched, filament spunbond), woven geotextiles (such as woven, knitted) and composite geotextiles (such as cloth film composite, warp knitted composite). The specific subdivisions cover functional products such as anti-seepage, drainage, and reinforcement.
1. Classification by production process Non-woven geotextiles Staple needle punched geotextiles: Made of polyester/polypropylene staple fibers, the fibers are randomly arranged and are suitable for scenes such as slope protection and roadbed isolation. ...
2. Classification by composite form Composite geotextile Such as "one cloth and one membrane" or "two cloths and one membrane", combined with anti-seepage membrane and non-woven fabric, used for landfill and tunnel anti-seepage.
Warp knitted composite geotextile Glass fiber reinforced, outstanding tear resistance, suitable for soft soil foundation reinforcement.
3. Classification by fiber material Polyester (PET) geotextile : High temperature resistant (-40℃~120℃), suitable for high temperature environment engineering.
Polypropylene (PP) geotextile : Corrosion-resistant, cost-effective, widely used in drainage systems.
Product specifications and standards
1. Common parameters
2. Industry standards
1. Suiyu Railway Test Section
Our country used geosynthetics in ballastless track for the first time, verifying the feasibility of polypropylene geotextile in the sliding layer.
2. Beijing-Shanghai High-speed Railway and Wuhan-Guangzhou High-speed Railway
CRTSⅠ/Ⅱ type slab track is widely used, and polypropylene geotextile is used as the key material of the isolation layer and sliding layer.
3. Zhengzhou-Xuzhou Passenger Dedicated Line
CRTSⅢ type track slab was used on a large scale for the first time, with 700g/㎡ high-strength polypropylene geotextile, marking the maturity of domestic production technology.
