Specifications of Needle Punched Nonwoven Geotextile for Highway Construction

 

Over the past decade a greater emphasis has been placed on the development and manufacturing of geosynthetic textiles. While the geosynthetics industry is comparatively new, it has already created products with applications in a wide range of industries including geotechnical, transportation, hydraulic, embankment management, and mining. In many cases, a single geosynthetic textile can solve or improve multiple civil engineering problems simultaneously.

The first example of a geosynthetic textile application is the use of a prefabricated pocket style vertical drain made from a nonwoven filter jacket specialized as a PVD filter material. The purpose of this product was to reduce the time needed for construction by quickly discharging water in the ground which speeds up the soil consolidation process. Overall, it proved to reduce construction time and speed up the consolidation of soft ground in a variety of different situations including road construction, the development of building sites, construction of gas and oil storage facilities, and bank revetment.

The second example of how geosynthetic textiles can provide solutions to civil engineering problems is the polyester woven geotextile mat. It is created from a high tenacity polyester filament which is highly dense. This particular geosynthetic textile has been used to reinforce soft ground and embankments, separate layers of sand and soft ground, prevent the uneven settlement of soft ground, and securing a safe path of travel for heavy equipment across soft ground.

The third example is a silt curtain or fence created by geosynthetic textiles. A silt curtain is installed in the water to prevent the spread of environmentally dangerous contaminants. These contaminants often result from coastal and Riverside construction projects although it can also be used in the event of an open water spill or leak. It has been shown effective at preventing the spread of fine soil and sand induced by construction. It can also prevent the contamination of the nearby seaports and help preserve sea farming and area beaches.

The fourth and final example of geosynthetic textiles assisting with civil engineering problems is the polyester needle punched nonwoven geotextile. It is typically made of continuous filament fiber to promote fast drainage and filtration. It has been used to help prevent landslides, control erosion on banks, protect waterproof layers in landfills, prevent road tracking, and protect waterproof sheets and tunnels.

There is no doubt geosynthetic textiles will continue to play a greater role in finding workable solutions to civil engineering problems across the globe. As their production continues to scale, prices will decrease which will lead to an increase in availability as well as further research and development.

Q:Filament non-woven geotextile, geomembrane, how much need to use third-party testing?
This depends on the party and the supervision requirements, and generally 1-2 million square a test batch, I am specializing in the production of geotechnical materials
Q:What is the latest price of geotextile?
Ask the geotextile price is too general, because the standard too much. Short wire, filament, polyester; non-standard, GB and so on. Ton price is generally between 4900-7500 yuan / ton, but the weight <200g, an increase of 100 yuan / ton; weight> 800g, an increase of 500 yuan / ton.
Q:What is the meaning of the geotextile What is its working principle
Hot geotextile cloth is to isolate the heat and cover a layer of geotextile material. Advantages: light weight, the overall continuity is good, high tensile strength, corrosion resistance, anti-microbial erosion is good, easy construction. Non-woven geotextile properties: small pore diameter, good permeability, soft texture, and soil with a good combination. 2, construction (1) according to the embankment or base wide full section laying. (2) leave sufficient anchorage length on each side of the embankment or substrate. (3) To ensure integrity, when the lap method is continuous, the lap length should be 0.3 ~ 0.5m. When the seam is connected, the bond width is not less than 50mm. (4) site construction, material damage must be immediately repaired. Upper and lower seams should be alternately staggered, staggered length of not less than 0.5m. (5) try to avoid prolonged exposure.
Q:Geotextile construction requirements of the use of adhesive specifications
Hello, geotextile construction is very simple, laying with less cutting, less overlap for the principle. Take the head set aside about 25 cm. Using double take the head, sew two lines. This is in principle to ask this, the general construction can not do so carefully. Huazhi geotechnical materials manufacturers to answer, need to talk.
Q:Geotextile production process
General spunbond, acupuncture, weaving, weaving, spunlace and other processes,
Q:Geotextile lap joint with special equipment? How is the price
Geotextile stitching is a professional equipment, professional equipment name for the portable sewing machine, the price is cheaper, generally ranging from 100-300 yuan. Look like this:
Q:Whether the geotextile filter layer includes a plastic mesh
Hello, geotextile can be used as a separate filter and grid sand with as a filter layer, Huazhi geotextile material manufacturers for you to answer
Q:What is the representative batch of geotextile?
Geotextile batch is 2000 square meters.
Q:Where the detection of geotextiles more authoritative
To the authority must find the authority of the body, the international authority was undoubtedly SGS, geotextile common test such as area weight, tear strength, puncture strength.
Q:Geotextile and geogrid the same do
Not the same, two concepts
