How many kinds of geogrid can we offer?

Geogrid is a major geosynthetic material, compared with other geosynthetic materials, it has unique properties and effects. Commonly used as reinforcement of reinforced soil structure or reinforcement of composite materials. Geogrid is divided into plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp knitted polyester geogrid four categories. The grid is a two-dimensional grid or a three-dimensional grid with a certain height made of polypropylene, polyvinyl chloride and other high polymer thermoplastic or molded, which is called a geogrid when used as a civil engineering.

1.Plastic:

Plastic bidirectional plastic geogrid is formed by stretching a square or rectangular polymer mesh material, according to the different tensile direction of its manufacturing can be unidirectional stretching and bidirectional stretching two kinds. It is made by punching holes in an extruded polymer sheet (mostly polypropylene or high-density polyethylene), and then subjected to directional stretching under heating conditions. Unidirectional tensile grille is only made along the length of the plate; The bidirectional stretch grille is made by continuing to stretch the unidirectional stretch grille and then stretching it in the direction perpendicular to its length.

Anti-aging materials such as carbon black are added in the production process of the geogrid, so it has good acid resistance, alkali resistance, corrosion resistance and anti-aging durability.

2.Mine-used

Mine grid is a coal mine with plastic protection net, polypropylene as the main raw material, after flame retardant, antistatic technology treatment, the use of bidirectional tensile method to form the overall structure of the "double resistance" plastic net. The product is convenient for construction, low cost, safe and beautiful.Compared with metal textile net and plastic woven net, mine geogrid has the characteristics of light weight, high strength, isotropy, antistatic, non-corrosion, flame retardant, and is a new type of mesh grid material used in coal mine underground support engineering and civil engineering.The product is mainly used in coal mine mining protection, can be used as bolt roadway, supporting roadway, shotcrete roadway and other roadway supporting materials. When used for false top, more than double layer combined use.

3.Steel-plastic

Steel-plastic geogrid with high-strength steel wire (or other fibers), after special treatment, with polyethylene (PE), and add other additives, by extrusion to become a composite high-strength tensile strip, and the surface has rough embossed, it is a high-strength reinforced earth belt. Thus, a single strip, arranged longitudinally and horizontally according to a certain distance or clamping, is formed by welding its junction points with a special fusion welding technology, which is a reinforced earth grid.Steel-plastic geogrid with plastic material as a protective layer, in addition to various additives to make it has anti-aging, oxidation properties, acid, alkali, salt and other harsh environment corrosion. Therefore, the steel-plastic geoglass can meet the needs of all kinds of permanent engineering for more than 100 years, and has excellent performance and good dimensional stability.Steel-plastic geogrid laying, lap, easy positioning, smooth, avoid overlapping and crossing, can effectively shorten the project cycle, save the project cost of 10%-50%.

4.Glass-fiber geogrid

Glass fiber geogrid is a mesh structure material made of glass fiber, using a certain weaving process. In order to protect glass fiber and improve the overall performance, it is a geocomposite material formed by a special coating process. The main components of glass fiber are: silicon oxide, is an inorganic material, its physical and chemical properties are very stable, and has high strength, high modulus, high wear resistance and excellent cold resistance, no long-term creep; Good thermal stability; The network structure makes the aggregate lock and limit; Improve the load bearing capacity of asphalt mixture. Because the surface is coated with special modified asphalt, it has a double compound property, which greatly improves the wear resistance and shear ability of the geogrid.

5.Polyester fiber warp knitting

Polyester fiber warp knitting geoglyph is selected with high strength polyester fiber as raw material. The warp knitted directional structure is adopted, the warp and weft yarns in the fabric have no bending state between each other, and the crossing points are bound together with high-strength fiber filaments to form a firm binding point, giving full play to its mechanical properties. The high-strength polyester fiber warp knitted geogrates have high tensile strength, small extension force, large tear strength, and small difference in vertical and horizontal strength. Ultraviolet aging resistance, wear resistance, corrosion resistance, light weight, and strong locking force with soil or gravel, it has a significant effect on strengthening the shear resistance of soil and strengthening the integrity and load of soil.

Features:

 High strength, small creep, adapt to all kinds of environmental soil, can fully meet the use of high grade highway retaining wall. It can effectively improve the interlocking and occlusal action of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively constrain the lateral displacement of the soil, and enhance the stability of the foundation. Compared with the traditional grid, it has the characteristics of high strength, strong bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform hole, convenient construction, long service life and so on. It is more suitable for deep-sea operations and embankment reinforcement, and fundamentally solves the technical problems such as low strength, poor corrosion resistance and short service life caused by long-term seawater erosion caused by other materials. It can effectively avoid construction damage caused by machine crushing and destruction in the construction process.

Applications:

1. Roadbed enhancement of various roads, railways and airports pavement enhancement.

2. Large parking lots and dock freight yards and other permanent load bearing foundation enhancement.

3. Slope protection of railway and highway.

4. Culvert enhancement.

5. The secondary enhancement of the soil slope after the enhancement of the unidirectional stretching geoglage can further enhance the soil slope and prevent soil erosion.

6. Reinforcement of mines and tunnels.
