The impermeable geomembrane is attributed to the drainage pipe, usually needle-punched nonwoven impervious geotextile, or woven impervious geotextile, waterproof impermeable geomembrane, it can be divided into two cloth films and cloth films, according to the plan to see the demand For how many grams of cloth and how many grams of film, roadbed penetration is usually acupuncture nonwoven impervious geotextile. Anti-seepage geotextile is a new type of construction material, its material is polyester, polyamide, polyamide and other polymer synthetic fibers.
According to the production method, it can be divided into two types: spinning anti-seepage geotextile and non-woven anti-seepage geotextile. Geotextile has the functions of waterproofing, filtering, drainage pipes, isolation, reinforcement design, protection, sealing, etc. It has the same waterproofing effect as conventional masonry and concrete materials, with less project investment, simple construction technology, short construction period, waterproof effect Advantages such as excellent, practical way. Waterproofing, slope protection, waterproofing and waterproofing of water conservancy projects.
Pavement, railway, airport runway foundation isolation, waterproof, drainage pipeline, slope protection, retaining wall and pavement reinforcement design, drainage pipeline; soft foundation treatment of port engineering, beach embankment, seaport and breakwater reinforcement design and drainage pipeline; residual garbage The isolation and anti-seepage geotextiles of landfills, thermal power plant ash dams, and dressing plant tailings dams have been widely used in the promotion of ground facilities, and are gradually being used in a wider range of industries.
Waterproof geotextile, also known as (composite geomembrane), is a geotechnical waterproof material made of plastic film as the waterproof substrate and combined with non-woven fabric. There are mainly polyvinyl chloride (PVC) and polyethylene (PE), which are a class of polymer chemically tough materials with small proportions, strong elongation, high applicable deformation level, corrosion resistance, heat resistance and good cold resistance.
Anti-seepage geotextile has the effect of filtering, filtering and strengthening design, and has water permeability! Anti-seepage geotextile is usually a combination of anti-seepage geomembrane and geomembrane, which is called combined anti-seepage geotextile, and may also be simply referred to as anti-seepage geotextile. Cloth and anti-seepage geotextile are permeable and water-to-earth. From the perspective of waterproof performance, anti-seepage geotextile is a combination product of anti-seepage geotextile and anti-seepage geotextile, which has the effect of waterproofing and waterproofing.
