Zhongloo HDPE Geocell Applications

Roadway load support

Cellular Confinement Systems (CCS) geocell have been used to improve the performance of both paved and unpaved roads by reinforcing the soil in the subgrade-base interface or within the base course. The effective load distribution of geo cel creates a strong, stiff cellular mattress. This 3D mattress reduces vertical differential settlement into soft subgrades, improves shear strength, and enhances load-bearing capacity, while reducing the amount of aggregate material required to extend the service life of roads. As a composite system, cellular confinement strengthens the aggregate infill, thereby simultaneously enabling the use of poorly graded inferior material (e.g. local native soils, quarry waste or recycled materials) for infill as well as reducing the structural support layer thickness. Typical load support applications include reinforcement of base and subbase layers in flexible pavements, including: asphalt pavements; unpaved access, service and haul roads, railway substructure and ballast confinement; working platforms in intermodal ports; airport runways and aprons, permeable pavements; pipeline support; green parking facilities and emergency access areas.

Steep soil slope and channel protection

The three-dimensional lateral confinement of HDPE geocell along with anchoring techniques ensures the long-term stability of slopes using vegetated topsoil, aggregate or concrete surfacing (if exposed to severe mechanical and hydraulic pressures). The enhanced drainage, frictional forces and cell-soil-plant interaction of plastic geocell prevents downslope movement and limits the impact of raindrops, channelling and hydraulic shear stresses. The perforations in the 3D cells allow the passage of water, nutrients and soil organisms. This encourages plant growth and root interlock, which further stabilizes the slope and soil mass, and facilitates landscape rehabilitation. Typical 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. They can be built as an underlying mass or as a facing. If you have any needs or questions, please feel free to contact us, Mary +8618130028453, mary@zhongloo.com, Anhui Zhonglu (www.zlgeo.com).

Earth retention

Main article: Mechanically stabilized earth

Honeycomb geocell provide steep vertical Mechanically stabilized earth structures (either gravity or reinforced walls) for steep faces, walls and irregular topography. Construction of Geocell grid 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 when suitable and granular, while the outer faces enable a green or tan fascia of the horizontal terraces/rows utilizing topsoil. Walls also can be used for lining channels and in cases of high flow, it is required that the outer cells contain concrete or cementous slurry infill. Gravel geocell have been used to reinforce soft or uneven soil foundations for large area footings, for retaining wall strip footings, for load sharing of covers over pipelines and other geotechnical applications. If you have any needs or questions, please feel free to contact us, Mary +8618130028453, mary@zhongloo.com, Anhui Zhonglu (www.zlgeo.com).

Reservoirs and landfills

CCS provides geomembrane 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 CCS functions as ready-made forms; CCS with concrete forms a flexible slab that accommodates minor subgrade movement and prevents cracking. In medium and low flow-velocities, CCS with geomembranes and gravel cover can be used to create impermeable channels, thereby eliminating the need for concrete.

Sustainable construction

GeoCell Ground Grid is a green construction solution that makes civil infrastructure projects more sustainable. In load support applications, the increased geocell reinforcement enables a reduction in the amount and quality of infill for structural support. This means that locally-available, but of marginal soil type or recycled materials can be used for construction. This reduces the need for quarry aggregate, thereby reducing quarrying, hauling and earthmoving placement equipment. This in turn decreases fuel use, pollution and the carbon footprint significantly, while at the same time lowering the construction environmental footprint in terms of less dust, erosion and runoff. When used for slope applications, perforated CCS provides excellent soil protection, water drainage and growth stratum for plants for the restoration of green and vegetated landscapes. Long-term design life of advanced CCS technology can also reduce maintenance and long-term economic costs. If you have any needs or questions, please feel free to contact us, Mary +8618130028453, mary@zhongloo.com, Anhui Zhonglu (www.zlgeo.com).
