Product Description:

 

Functions of Non-woven Geotextile for Tunnel Engineering:

 

1.Separation
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different.granule pathway from the groundsill or other buildings. 

2.Reinforcement
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability. 

3.Protection 
It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away

Q:Composite geotextile 20-500-0.5 what it means
0.5 should be the film thickness of 20-500. Did not understand the estimated cloth is the bar, not like
Q:Specification for Lap Length of Geotextile with Two Cloth
10 cm or so can be, collar Xiang new materials for your answer
Q:Geotextile with the welding tool where to buy
I am the manufacturer
Q:Shield Machine Tool material which is the hardest
Carbide blade is the hardest,
Q:How much is the geotextile machine?
Cheaper point of the 4500 better 8,000 more
Q:Geotextile drainage network and geotextile how to heat stick
Geotextile and geotextile crimp part of the use of sewing or hot air welding. Hot air welding is the connection method of filament geotextile, that is, with the hot air gun on the connection of two pieces of cloth instantaneous high temperature heating, so that part of the molten state, and immediately use a certain external force to make it firmly together. In the case of wet (rain and snow) weather can not be hot adhesive connection, geotextile should take another method of a suture connection method, that is, with a dedicated sewing machine for two-wire suture connection, and the use of anti-chemical UV suture.
Q:Is the current tunnel construction, modular waterproof board (geotextile) is available?
We use the soil is a geotech cloth waterproof board
Q:Do you need to cover the geotextile?
Do not need, bathroom waterproof can choose a professional kitchen and toilet waterproof paste, or K11 waterproof slurry, water and electricity transformation, as long as the direct brushing on the base surface can be done until the waterproof layer can do 48 to 72 hours Of the closed water experiment, no problems can be posted after the brick.
Q:Large area square construction, drainage board layout through the water pipe
Set aside the road to pull the car, little by little to fill the soil, I am specializing in the production of geotextile, drainage board, wish smooth
Q:Geomembrane and geotextile difference?
1, geotextile, also known as geotextile, it is made of synthetic fiber through acupuncture or woven from the permeability of geosynthetics. Finished cloth for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into a woven geotextile and non-woven geotextile. Geotextile has excellent filtration, drainage, isolation, reinforcement, anti-seepage, protection, with light weight, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion resistance. 2, geomembrane construction site geomembrane to plastic film as impermeable substrate, and non-woven composite made of soil impermeable material, its impermeability depends mainly on the plastic film impermeability. At present, domestic and foreign anti-seepage application of plastic film, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), they are a polymer chemical flexible material, the proportion of small, Strong extension, high adaptability to deformation, corrosion resistance, low temperature resistance, good frost resistance. The main mechanism is to plastic film impermeable barrier earth dam leakage channel, with its large tensile strength and elongation to withstand water pressure and adapt to the dam deformation; and non-woven is also a polymer short fiber chemistry Material, through the needle or hot tack forming, with high tensile strength and extensibility, it is combined with the plastic film, not only increased the tensile strength of plastic film and anti-puncture ability, and because the non-woven surface rough , Which increases the friction coefficient of the contact surface, which is favorable to the stability of the composite geomembrane and the protective layer. At the same time, they have good resistance to bacteria and chemical resistance, not afraid of acid, alkali, salt erosion.
