Geotextile Irregularly arranged fibers are bonded
As the current geotextile production of synthetic fibers mainly nylon, polyester, polypropylene, Ethylene, they have a strong anti-burial, corrosion resistance
Geotextile for the permeable material, so it has a good anti-filter isolation function
Non-woven geotextiles due to the structure of fluffy, with good drainage performance
Green geotextile performance, geotextile is a new type of building materials, raw materials are polyester, acrylic, nylon and other polymer polymer synthetic fiber. According to the manufacturing method is divided into: there are two types of geotextile and non-woven geotextile. There are geotextile - that is, geotextile woven geotextile. Its thickness is thin, the general thickness of 0.2mm, 0.4mm, 0.7mm. Its tensile strength is strong, about 250kg / cm2, the permeability coefficient is larger, about 6.1 × 10-4cm / s, and the texture is stable, good durability. Non-woven geotextile - that is, irregularly arranged fibers are bonded, acupuncture made of mesh. Commonly used is a needle-type non-woven geotextile. This type of geotextile has a strong compressibility, porosity, water conductivity is better, better than a spinning cloth. Geotextile with anti-seepage, anti-filtration, drainage, isolation, reinforcement, protection, sealing and other functions, it with the conventional masonry and concrete material seepage effect compared to a low investment, simple construction process, Infiltration effect is good, the channel effective use of high coefficient, such as Xianyang City Weihe River dike project construction, targeted to the two embankment, respectively, using geotextile and traditional methods of construction. After two kinds of construction program comparison, the use of geotextile construction of 500m embankment, a total investment of 205,500 yuan, 15,600 working days labor. And the traditional program to build the same length of the river embankment, you need to invest 273,700 yuan, 18,400 working days labor, the two programs compared to the use of geotextile new materials, investment, investment can be reduced by 25% and 15%. Baoji Gorge irrigation area in the eastern section of the four water conservation, the North trunk 72km rescue project successfully used this new material, not only achieved significant anti-seepage effect, and reduce investment, shorten the duration, can be described as multiple purposes.
Geotextile has a good anti-puncture ability, so it has a very good protective performance
Construction, should try to avoid the stone directly hit the geomembrane, the best side of the film side of the protective layer of the construction. Composite geomembrane and the surrounding structure should be connected with expansion bolts and steel plate pressure bar anchorage, the connection site to brush the emulsion asphalt (thickness 2mm) bonding, to prevent the occurrence of leakage. Geomembrane seams processing is a key process, HDPE geomembrane directly affect the anti-seepage effect.
Electrical engineering: nuclear power plant basic engineering; thermal ash dam project; hydropower project.
Geotextile has a good coefficient of friction and tensile strength, with geotechnical reinforcement performance
Waterproof geotextile to plastic film as anti-seepage substrate, and non-woven composite made of soil impermeable material, its impermeability depends mainly on the plastic film impermeability.
Highway and railway engineering: soft foundation reinforcement treatment; slope protection; road anti-reflective crack structure layer; drainage system; green isolation zone.
Water conservancy projects: seawall, river embankment, lake embankment standard project; reservoir reinforcement project; reclamation project; flood control and rescue.
