Mechanism:
Unidirectional geogrid: The mechanism for strengthening the soil lies in the interaction between the grid and the soil. Generally it can be summarized as the friction between the surface of the grille and the soil; the locking effect of the grille holes on the soil and the passive resistance of the grille ribs. All three effects can fully restrain the lateral displacement of soil particles, thereby greatly increasing the soil's own stability, and the effect of soil reinforcement is significantly higher than other geotextiles.
Unidirectional geogrid: This structure has quite high tensile strength and tensile modulus. The tensile strength reaches 100-200Mpa, which is close to the level of low carbon steel, which is much better than traditional or existing reinforced materials. In particular, this type of product has ultra-international high early strength (elongation between 2% and 5%) tensile strength and tensile modulus. It provides the soil with an ideal chain system of load bearing and diffusion. This product has high tensile strength (> 150Mpa), adapts to various soils, and is currently widely used as a reinforcing material. Its main characteristics are: high tensile strength, good creep performance, convenient construction, and low price.
