GES GEOCELLS
GES Geocell is used for Soil reinforcement and it is a versatile method in terms of its cost effectiveness for the improvement of the strength of soft soils. It is the latest form of reinforcement which is both economical and durable in long term. It provides all round confinement to the materials hence it prevents the lateral spreading of soil on the application of load. So the use of geocell reinforcement increases the strength and stiffness property of the soft soil.
BENEFITS OF USING GES GEO CELL
GES GEOCELL is very effective as the cellular confinement systems have more attractive features due to its 3D structure. Hence geocell can provide better lateral confinement to infill soils. The reinforced composite formed by the geocell and the infill soil has a higher stiffness and shear strength than the unreinforced soil. These cells completely encases weak material such as soil, stones, etc. and provide all round confinement due to its three dimensional structure thus preventing the lateral spreading of the material due to which, a much stiffer mat like structure is formed and distributes the overcoming load to a much wider area.
ADVANTAGES
- High Strength Tendons through the Geocell panels provide Permanent Anchorage in the Crest of the Slopes, eliminating the Risk of the Material Sliding Down the Slope.
- Supports Vegetation for True Long Term Landscaping and Erosion Control
- Quick, Efficient and Safe Installation to save Project Time and Cost.
- Helps in Carbon Footprint Reduction.
APPLICATION
- In Steep soil slope and channel protection
- In Pavement and Road Construction
- In Reservoirs and landfills
- In Slope Protection
- In Earth retention
- In Foundation
- In Railway
HOW IT WORKS?
GES GEOCELL when infilled with compacted soil creates a new composite entity that possesses enhanced mechanical and geotechnical properties. When the soil contained within a geocell is subjected to pressure, as in the case of a load support application, it causes lateral stresses on perimeter cell walls. The 3D zone of confinement reduces the lateral movement of soil particles while vertical loading on the contained infill results in high lateral stress and resistance on the cell-soil interface. This increase the shear strength of the confined soil, which:
- Creates a Stiff Mattress or Slab to Distribute the Load over a Wider Area.
- Increases Shear Resistance and Bearing Capacity.
- Reduces Punching of Soft Soil.
- Decreases Deformation.
Confinement from adjacent cells provides additional resistance against the loaded cell through passive resistance, while lateral expansion of the infill is restricted by high hoop strength. Compaction is maintained by the confinement, resulting in long-term reinforcement.
On site, the geocell sections are fastened together and placed directly on the subsoil’s surface or on a geotextile filter placed on the subgrade surface and propped open in an accordion-like fashion with an external stretcher assembly. The sections expand to an area of several tens of meters and consist of hundreds of individual cells, depending on the section and cell size. They are then filled with various infill materials, such as soil, sand, aggregate or recycled materials and then compacted using vibratory compactors. Surface layers many be of asphalt or unbound gravel materials.
PRODUCT DETAILS
The Behaviour of GES GEOCELLS made of woven coir geotextiles, placed over soft soil, was studied by varying the width, height and cell size through model tests. The studies have shown that, with the provision of geocell-reinforced sand cushion, there is a substantial reduction in settlement of the underlying soft soil due to modified stress distribution. The beneficial effect in terms of increased bearing capacity and reduced settlement is proportional to the width, height and cell size of coir geocell mattress. Optimum width, height and cell size of coir geocell were derived from the model tests. A tenfold increase in bearing capacity of soft clay is obtained by the provision of geocell reinforcement in the system.
