Specifications of Geogrid:


Warp-knitting Polyester Geogrid adopts industrial high strength, high modulus and low shrinkage twisting polyester fiber as raw material. With warp-knitted directional structure, there is no bend statement among warp and weft yarns of the fabric. The cross points of the geogrid are bundled and banded together by high-strength polyester fiber. So they form solid binding points. After coating with high-quality oil or water-soluble PVC, its physical and chemical property is greatly optimized.ams and dikes, and mountain slope 2) Can prevent land soil from water and rain erosion before grass covering grows 3) Can bear sourcing of high water space and high-speed water after grass covering grows 4) It can reduce cost of construction by width margin and the cost is only 1/7 concrete,1/8 stone 5) It adopts macromolecule material and anti-UV rays stability, and its chemical character is very stable, and there is no pollution to environment 6) Easy construction after surface of land is smooth 7) A kind of three dimensional structure new-type geosynthetical materials suitable for protecting water and land soil 8) Can effectively prevent water and land soil from flowing away, increase green land and improve living environment Operation: 1) Can use bamboo pole or wood stick pass the whole roll net mat during construction, then pull net mat along slope, use wooden nail or plastic nail to fix four circle of net mat, distance between nails is 750px, one square meter has 10 nails 2) Length of nail from land surface is usually 375px, add nails on loose land, length of nail on up slope is longer than on down slope when construction on high slope 3) Pay attention to keep netting mat smoothl



Applications of Geogrid: 
Make reinforce treatment for various kinds of soft soil foundation to evenly distribute load stress and reduce uneven settlement, not easy to generate static electricity, and flammability property good in the coal mine. It is easy to wash coal. 

Used in highway, railway, port, airport and municipal project. Support in the recovery working face of coal mine and roadway in the coal mine.

Q:What type of geogrid is CATTXDJ?
1 Introduction geogrid: Geogrid geogrid is a kind of main geosynthetics, which has unique properties and effects compared with other geosynthetics. Geogrid is often used as reinforcement of reinforced soil structure or composite material. Geogrid is divided into four categories: plastic geogrid, steel plastic geogrid, fiberglass geogrid and polyester warp knitted polyester geogrid. 2 classification of plastic woven through the formation of a square or rectangular polymer mesh material, according to the direction of its manufacturing can be different for different types of uniaxial tension and biaxial tensile two
Q:What is the single geogrid 60kN/m
60kN/m refers to the direction of force.
Q:What are the advantages of unidirectional polyester geogrid in cost and two-way
First talk to the function of it, compared with the similar functions, There are both advantages and disadvantages., but the cost of bidirectional geogrid is more expensive! Construction is the same! The difference lies in the cost! Thank you
Q:How much is a square metre?
Geogrid plays a very important role in road construction, which is mainly to reinforce roadbed and delay aging. The following is a detailed introduction: Geogrid on the road is mainly used for soft foundation treatment, roadbed reinforcement, slope protection, abutment reinforcement, wing wall, retaining wall, isolation and reinforcement of soil engineering.
Q:What kind of experiments need to be done to check geogrid
Or the same as the first inspection, different places are not the same as the results of some of the equipment testing may be out, but the probability is not. The company specializes in the production of Geogrid
Q:How to determine geogrid reinforcement or crack resistance
The old asphalt roadbed, will appear two different mutations in the direction of force wheel edge, a vertical load is the downward force of a horizontal tensile stress, long-term effect, and the influence of temperature and humidity, it is prone to fatigue cracking and subsidence layer to asphalt and asphalt overlay layer, caused by roadbed disease. According to the old asphalt roadbed fatigue cracking stress analysis by the line, in the asphalt layer and between concrete rigid base layer paving surface coating modified asphalt and self adhesive pressure sensitive adhesive of glass fiber geogrid in asphalt overlay and rigid concrete layer to form a good buffer zone, effective release of two mutations, prevent crack disease.
Q:What is the action mechanism
Glass fiber geogrid / glass fiber grille with glass fiber rovings as main raw materials, the reticular structure material of the knitting process, for the protection of glass fiber, improve the overall performance, through a special coating treatment process and the formation of new excellent geotechnical materials. Glass fiber has high heat resistance and excellent cold resistance, high strength, high modulus, good chemical stability, corrosion resistance, low coefficient of expansion, good dimensional stability and so on
Q:High density polyethylene one-way geogrid, tensile yield of 20kn/m
Material is high density polyethylene material
Q:Geogrid nailed pictures and size
U type nails, like the letter U, geogrid generally 0.6 multiplied by 80. You can also process
Q:Classification and characteristics of geogrids
Two, steel plastic composite geogrid:1 high strength steel wire, steel plastic composite geogrid tension by warp knitting bear, resulting in high tensile modulus at low strain capacity, vertical and horizontal rib synergistic effect, give full play to the role of Geogrid on soil type.2, steel plastic composite geogrid vertical steel rib weft woven into nets, an outer coating layer forming a steel wire and the outer coating layer can destroy the function of coordination, elongation is very low (less than 3%). The main force unit of steel plastic composite geogrid is steel wire, and the creep is very low.3, through the production process of plastic surface treatment, suppress the rough pattern, in order to enhance the surface roughness of the grid, improve the steel plastic composite geogrid and soil friction coefficient.4, steel plastic composite geogrid width of up to 6m, to achieve high efficiency, economic effect of reinforcement.5, steel plastic composite geogrid used high-density polyethylene can ensure that: at room temperature will not be affected by acid and alkali and salt solution, or oil erosion; will not be dissolved by water or microbial damage. At the same time, the high molecular weight of polyethylene is also sufficient to resist ultraviolet radiation caused by aging. The grille stress aspect rib synergistic effect, can not generate node crack or damage. But in the actual project, after the packing compaction, therefore has not been affected by ultraviolet light and oxygen.
