1. Recyclable High-Density Polyethylene (HDPE) Material
Geocell utilizes reinforced HDPE film, which offers excellent aging resistance, acid and alkali resistance, and a long service life. It can be recycled and reused after many years, reducing waste generation.
2. Reduced Material Transportation and Construction Energy Consumption
Because Geocell is foldable and compact, it can be deployed on-site, significantly reducing the distance and frequency of transportation of traditional earthwork materials, thereby reducing fuel consumption and carbon emissions.
3. Reduced Dependence on Natural Resources
By increasing soil strength through three-dimensional constraints, less filler or gravel can be used for the same load-bearing capacity, reducing the need for quarrying natural resources like stone and sand, and minimizing damage to the ecological environment.
4. Safety for Soil and Water
HDPE is chemically stable and does not release harmful substances into the soil or groundwater. It is suitable for use in special environments such as saline-alkali soils and expansive soils, avoiding secondary pollution.
What is the actual effectiveness of Geocell in road base reinforcement?
1. Significantly Improved Bearing Capacity and Settlement Resistance
Experiments have shown that the addition of Geocell reduces soil surface settlement by approximately 29% to 43%. Under the same load, overall subgrade settlement is significantly reduced, extending the road's service life.
2. Enhanced Lateral Constraint and Improved Shear Strength
Through three-dimensional constraint, Geocell can increase soil shear stress by 15% to 30%. This effect is particularly pronounced when the Geocell height is increased, effectively resisting lateral displacement caused by vehicle loads.
3. Improved Drainage and Erosion Resistance
Under rainwater erosion conditions, the Geocell structure reduces pore water pressure, indirectly increasing soil cohesion and friction angle, significantly slowing slope displacement and erosion rates. This effect is particularly pronounced on slopes greater than 1:1.5.
4. Convenient Construction and Cost Advantages
Because Geocell can be quickly tensioned and folded for transportation on site, the construction period is shortened by over 30%, material procurement and transportation costs are significantly reduced, and the overall project cost-effectiveness is improved.
