Geocell (Geocell Ground Grid) – Geofantex

The Applications of Geocell (Geocell Grid) – Geofantex

• Used to stabilize road and railway subgrades.
• It is used for dikes and shallow rivers that bear the load.
• Mixed retaining walls are used to prevent landslides and loaded gravity.
• When encountering soft foundations, the use of geocells can greatly reduce the labor intensity of construction, reduce the thickness of the roadbed, the construction speed is fast, the performance is good, and the project cost is greatly reduced.

Geocell (Geocell Ground Grid) Role in engineering – Geofantex

• Deal with half-filled and half-cut subgrade: When building an embankment on a slope where the natural slope of the ground is steeper than 1:5, the embankment base should be dug steps, and the width of the steps should not be less than 1M. When the road is built or rebuilt in phases and the road is widened, the junction of the new and old subgrade fill slopes should be opened. For digging steps, the width of the high-grade highway steps is generally 2M, and the geocell is laid on the horizontal surface of each step, and the geocell’s own elevation confinement reinforcement effect is used to better solve the problem of uneven settlement.
• Roadbed in sandy areas: Low embankments should be the main roadbed in sandy areas, and the filling height is generally not less than 0.3M. Due to the professional requirements for low roadbeds and heavy loads in sandy areas, the use of geocells can limit loose fillers. The limited height ensures that the roadbed has high rigidity and strength to withstand the load stress of large vehicles.
• Filling and reinforcement of the subgrade behind abutment: The use of geocells can better achieve the purpose of reinforcement of the abutment back. Sufficient friction can be generated between the geocell and the filler, which can effectively reduce the uneven settlement between the subgrade and the structure, and finally can effectively alleviate the “abutment jump”. Early impact damage to the bridge deck caused by the “car” disease.
• Roadbed in permafrost regions: The minimum fill height should be reached in the construction of filled roadbeds in permafrost regions to prevent the occurrence of tumbling or the lowering of the upper limit of the frozen layer, resulting in excessive settlement of the embankment. The unique vertical reinforcement effect of the geocell and the effective implementation of the overall confinement can ensure the minimum fill height in some special sections to the greatest extent, and make the fill have high-quality strength and rigidity.
• Treatment of collapsible loess roadbed: When expressways and first-class highways pass through collapsible loess and loess sections with good compressibility, or when the allowable bearing capacity of the foundation of a high embankment is lower than the pressure of the combined load of vehicles and the self-weight of the embankment, the subgrade should also be adjusted according to the bearing capacity requirements. After processing, the superiority of the geocell is undoubtedly evident.
• Saline soil and expansive soil: Reinforcement measures are adopted for highways, first-class highways, shoulders and slopes built with saline soil and expansive soil. The facade reinforcement effect of the cell is the most excellent one of all reinforcement materials, and it has excellent corrosion resistance. It can fully meet the requirements of constructing highways in saline soil and expansive soil.
