Two-way geogrid

Two-way Geogrid two-way geogrid

The two-way geogrid is a major geosynthetic material with unique properties and efficacy compared to other geosynthetics. Two-way geogrids are often used as reinforcements for reinforced earth structures or composite materials.

(1) Two-way geogrid is a product of plastic geogrid

The plastic geogrid is a square or rectangular polymer mesh which is formed by stretching, and may be uniaxially stretched or biaxially stretched according to the direction of stretching in the manufacture. It is punched on a extruded polymer sheet (mostly polypropylene or high density polyethylene) and then subjected to oriented stretching under heating. The unidirectionally stretched grid is stretched only along the length of the sheet, while the biaxially stretched grid is continuously stretched by stretching the unidirectionally stretched grid in a direction perpendicular to its length.

Since the polymer of the geogrid in the manufacturing process is rearranged and oriented with the heating extension process, the bonding force between the molecular chains is strengthened, and the strength is improved. Its elongation is only 10% to 15% of the original board. If an anti-aging material such as carbon black is added to the geogrid, it can have good durability against acid, alkali, corrosion and aging.

Two-way geogrid

The two-way geogrid is formed by extruding, forming a plate and punching a high-molecular polymer and then stretching it longitudinally and transversely. The material has great tensile strength in both the longitudinal and transverse directions. This structure also provides an ideal interlocking system for more efficient force bearing and diffusion in the soil, suitable for large-area permanent bearing. foundation

Uses: Two-way geogrid is suitable for reinforcement of various dams and subgrades, protection of slopes, reinforcement of cave walls, and reinforcement of permanent foundations such as large airports, parking lots and terminal yards.

1. Increase the bearing capacity of the road (ground) base and extend the service life of the road (ground) base.

2. Prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy.

3. Convenient construction, saving time, labor, shortening construction period and reducing maintenance costs.

4. Prevent cracks in the culvert.

5. Strengthen the slope to prevent soil erosion.

6. Reduce the thickness of the cushion and save the cost.

7. Support the stability of the slope and grass mat to green the environment.

8. Can replace the metal mesh for the false roof network in coal mines.
