GEOKARKAS PG

详情

Geocell products are three-dimensional, expandable panels made from high-density polyethylene (HDPE). When expanded during installation, the interconnected strips form the walls of a flexible, three-dimensional cellular structure into which specified infill materials are placed and compacted.
Application range of GEOKARKAS PG
- protection and stabilization of steep slope surfaces
- protective linings of channels and hydraulic structures
- static and dynamic load support on weak subgrade soils
- multi-layered earth-retaining and water-retaining gravity structures.
Paved Roads
GEOKARKAS PG have been used to improve the performance of paved roads by reinforcing the soil in the subgrade-base interface or within the base course. The effective load distribution of GEOKARKAS PG creates a strong, stiff cellular mattress. The introduction of this Geocell
GEOKARKAS PG reduces the vertical differential settlement into soft subgrades, this inturn improves shear strength, and enhances load-bearing capacity whilst reducing the amount of aggregate material required to extend the service life of roads.
Slope and Channel Protection
The GEOKARKAS PG along with anchoring techniques ensures the long-term stability of slopes using vegetated topsoil and aggregate. The enhanced drainage, frictional forces and cell-soil-plant interaction created by the CCS prevents downslope movement and limits the impact of rain and hydraulic shear stresses. The perforations in the cells allow water, nutrients and soil organisms to pass through the soil which encourages plant growth and root interlocking. The interlocking of the roots further stabilizes the slope and soil mass.
Common applications include: construction cut and fill slopes and stabilization; road and rail embankments; pipeline stabilization and storage facility berms; quarry and mine site restoration; channel and coastline structures.
Earth Retention
GEOKARKAS PG systems provide steep vertical mechanically stabilized earth structures (either gravity or reinforced walls) for steep faces, walls and irregular topography. Construction of GEOKARKAS PG earth retention is simplified as each layer is structurally sound thereby providing access for equipment and workers, while eliminating the need for concrete formwork and curing. Local soil can be used for infill therefore reducing the amounts of material that needs to be outsourced.
Reservoirs and Landfills
GEOKARKAS PG provides membrane liner protection, while creating stable soil, berms and slopes, for non-slip protection and durable impoundment of liquids and waste. Infill treatment depends on the contained materials: concrete for ponds and reservoirs; gravel for landfill drainage and leachates,
vegetated infill for landscape rehabilitation. Concrete work is efficient and controlled as GEOKARKAS PG functions as ready-made forms; GEOKARKAS PG with concrete forms a flexible slab that accommodates minor subgrade movement and prevents cracking. In medium and low flowvelocities,
GEOKARKAS PG with geomembranes and gravel cover can be used to create impermeable channels, thereby eliminating the need for concrete.
