The geogrid produced by the geogrid production line equipment has achieved good results in roadbed reinforcement engineering due to its characteristics of high strength, low creep, and strong adaptability. However, research on the optimization of parameters for geogrid reinforcement of soft soil roadbed still needs further improvement. Based on this, taking a soft soil roadbed widening project as an example, a finite element analysis model for widening the roadbed was established. A comparative analysis was conducted on the influence of different layers of geogrid laying on the deformation, stress, and stability of the new and old roadbed, and a more reasonable number of geogrid laying layers was finally determined.

The reinforcement effect of geogrids does not result in a difference in nominal soil pressure between high and low levels of geogrids slightly away from the baffle. Instead, it improves the stress and deformation inside the soil by adjusting the shear stress of high and low levels and generating tension within itself to balance the difference in shear stress, and then realizes the purpose of reinforcement. Geogeosynthetic material is a major type of geosynthetic material that, compared to other geosynthetic materials, has unique performance and efficacy.

What aspects are the grids produced by the geogrid production line equipment applied to

1. Unidirectional tensile plastic geogrid is a high-strength structural material suitable for strengthening roadbeds such as highways, municipal roads, railways, and aircraft runways.

2. Suitable for strengthening embankments in rivers and seas.

3. Suitable for fences in orchards, vegetable fields, livestock, land, etc., safe and convenient to use, easy to disassemble, and aesthetically pleasing.

4. Suitable for reinforced soil retaining walls on highways, municipal roads, railways, aircraft runways, and riverbanks.

5. Suitable for retaining walls, abutments, steep slope engineering, etc.

The carbon black content testing requirement for plastic geogrids must not be less than 2.0%. In terms of creep performance, it is required that the measured creep conversion coefficient must meet the age requirements of engineering design. And in terms of important mechanical properties. The main testing indicators required by GB/T 17689-2008 are tensile strength, tensile strength at 2% elongation, tensile strength at 5% elongation, and nominal elongation. And if it is a polypropylene double pull plastic grille, both longitudinal and transverse tensile tests are required.

During the manufacturing process of bidirectional plastic geogrids, the polymer polymers will rearrange and orient with the heating extension process, strengthening the bonding force between molecular chains and achieving the goal of improving their strength. Its elongation is only 10% to 15% of the original plate. If anti-aging materials such as carbon black are added to the geogrid, it will have better durability such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
