Functions of Honeycomb Geocell for Subgrade Reinforcement

Working Mechanism of Subgrade Reinforcement

1. Lateral Confinement to Lock Aggregate (Core Function)

Independent honeycomb cavities lock loose crushed stone and sand, restricting lateral flow and outward expansion of fillers. Loose granular materials are integrated into an integral rigid slab, increasing soil shear strength by 2 to 3 times and eliminating pavement shifting and rutting under heavy loads.

2. Uniform Load Distribution

Concentrated wheel pressure from vehicles is dispersed to a wider area of the original subgrade via the honeycomb grid, significantly reducing vertical compressive stress on subgrade soil and cutting differential settlement by 40%~65%.

3. Drainage and Pressure Relief (Perforated Geocell)

It rapidly drains accumulated water inside soft subgrades, lowers soil moisture content, improves bearing capacity of soft soil, and prevents subgrade mud pumping and spring soil in rainy weather.

4. Thinner Cushion Layer & Balanced Stiffness

It reduces stiffness differences between new and old subgrades as well as transition sections of bridges and culverts, alleviating expansion cracks and pavement slab fracture problems.
