Geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers through needle punching or weaving. The finished product is in the form of cloth, generally with a width of meters and a length of meters. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextile has excellent filtration, drainage, isolation, reinforcement, anti-seepage, and protective functions. It has light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance. Introduction to geotextile
Geotextile is a new type of building material. The raw materials are synthetic fibers of polyester, polypropylene, acrylic, nylon and other high molecular polymers. According to the manufacturing method, it is divided into two types: non-woven geotextile and woven geotextile. Non-woven geotextiles are mainly used in general projects and have multiple functions such as anti-seepage, reverse filtration, drainage, isolation, reinforcement, protection, sealing, etc. Compared with the anti-seepage effect of conventional masonry and concrete materials, it has an investment Low cost, simple construction technology, short construction period, good anti-seepage effect, and high channel effective utilization coefficient.
Characteristics of geotextile
High strength. Due to the use of plastic fibers, it can maintain sufficient strength and elongation in wet and dry conditions.
, Corrosion-resistant, can resist corrosion for a long time in soil and water with different pH levels.
, good water permeability. There are gaps between fibers, so it has good water permeability.
It has good anti-microbial properties and is not damaged by microorganisms and insects.
, Convenient construction. Because the material is light and soft, it is convenient to transport, lay and construct.
, complete specifications and width up to meters. It is currently the widest product in China, with mass per unit area/square meter.
Function of geotextile
Isolation
Polyester staple fiber needle-punched geotextile is used to protect building materials (such as soil and sand) with different physical properties (particle size, distribution, consistency and density, etc.) particles, soil and concrete, etc.) for isolation. It prevents the loss or mixing of two or more materials, maintains the overall structure and function of the materials, and enhances the load-bearing capacity of the structure.
Filtration (reverse filtration)
When water flows from the fine soil layer into the coarse soil layer, the good air permeability and water permeability of the polyester staple fiber needle-punched geotextile are used to allow the water to pass through and effectively Carrying soil particles, fine sand, small stones, etc. to maintain the stability of water and soil engineering.
Drainage
Polyester staple fiber needle-punched geotextile has good water conductivity. It can form drainage channels inside the soil to drain excess liquid and gas out of the soil structure.
Reinforcement
Use polyester staple fiber needle-punched geotextile to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil.
Protection
When water flows against the soil, it effectively diffuses, transfers or decomposes the concentrated stress, preventing the soil from being damaged by external forces and protecting the soil.
Anti-Puncture
Combined with the geomembrane to form a composite waterproof and anti-seepage material, it can prevent puncture.
High tensile strength, good permeability, air permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, and no insects.
Polyester staple fiber needle-punched geotextile is a widely used geosynthetic material. It is widely used in railway roadbed reinforcement, highway pavement maintenance, sports halls, dam protection, hydraulic construction isolation, tunnels, coastal beaches, reclamation, environmental protection and other projects.
Application areas of geotextiles
Used as reinforcement in retaining wall backfill, or used to anchor retaining wall panels. Build wrapped retaining walls or abutments.
Reinforce flexible pavement, repair cracks on the road, and prevent reflective cracks on the road.
Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage to the soil at low temperatures.
The isolation layer between the road ballast and the roadbed, or the isolation layer between the roadbed and the soft base.
The isolation layer between artificial fill, rock or material field and foundation, and the isolation between different frozen soil layers. Filtering and reinforcement.
The filter layer on the initial upstream dam surface of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill soil of the retaining wall.
The filter layer around the underground drainage pipe or the gravel drainage ditch.
The filter layer of water wells, pressure relief wells or baroclinic pipes in water conservancy projects.
Geotextile isolation layer between highways, airports, railway tunnels, artificial rockfills, etc. and the foundation.
The interior of the earth dam is drained vertically or horizontally, and is buried in the soil to dissipate the pore water pressure.
Drainage behind the anti-seepage geomembrane or under the concrete face in earth dams or embankments.
Eliminate water seepage around the tunnel and reduce external water pressure on the lining and water seepage around the buildings.
Drainage of sports ground foundation on artificial fill foundation.
Used to strengthen weak foundations in highways (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields and other projects.
