Geocell is a lightweight and flexible three-dimensional, expandable
panels made from High Density Polyethylene (HDPE) strips which are
ultrasonically bonded together to form an extremely strong
configuration.
When infilled by compacted soil, a Cellular
Confinement System (CCS) is to create a new entity with enhanced
mechanical and geotechnical properties. When pressure applied to the
soil contained in a CCS, it results in a lateral stress on the perimeter
of the cell wall. The three-dimensional confinement area reduces the
lateral movement of soil particles. the vertical load applied to
contained infill lead to high stress and resistance to lateral interface
between cell and soil.
Constrained adjacent cell provides
additional resistance filled by passive resistive load cell, while the
horizontal expansion by restricting the ring of high strength.
Compaction is maintained to result in long-term reinforcement.
On
the jobsite, all sections of geocell are fastened together and placed
directly on the surface of the subsoil or placed on the geotextile
covered on the roadbed surface. the sections are stretched and expanded
with stretcher. geocell extended to cover several tens of meters may
consist of hundreds of individual cells, depending on the size of the
section and the whole area. They are then filled with a variety of
filler materials such as soil, sand, aggregate or recycled materials,
and then compacted using vibration compaction.
Overall CCS can
create a hard mattress to distribute the load over a wider area, reduce
settlement of soft soil, improve shear resistance and load carrying
capacity and reduce distortion.
