Cellular Confinement System Information
Cellular Confinement System(CCS)--also known as geocell, it is a
kind of three-dimensional network structure shaped by high-strength
HDPE (high density polyethylene) sheets through ultrasonic welding
of high strength. The depth of the geocells as well as the size of
each cellular unit can vary as per design requirements. The surface
of geocells are smooth or textured, the textured geocells increase
soil-geocell wall friction. Geocells can be perforated or
non-perforated. If the depth of geocell is over 10cm, the geocell
can be perforated, the geocell wall is punctured to assist in
immediate dissipation of developed porewater pressures due to
increased stresses within the infill of the individual cells.

Cellular Confinement System Applications
1, Treatment of half filling and half subgrade: when building
embankment on the slope with natural gradient of 1:5, steps shall
be excavated at the base of embankment, and the width of steps
shall not be less than 1m. When widening the road by stages or
reconstruction, steps shall be excavated at the junction of new and
old subgrade filling slopes. The width of steps for high-grade
highway is generally 2m, and geocells shall be laid on the
horizontal surface of each step The reinforcement effect of its own
facade can better solve the problem of uneven settlement.
2. Subgrade in windy sand area: the subgrade in windy sand area
shall be mainly low embankment, and the filling height shall not be
less than 0.3m. Due to the special and industrial requirements of
Low Subgrade and heavy load-bearing of Subgrade in windy sand area,
the use of geocell can limit the loose filler, ensure the subgrade
has high stiffness and strength within the limited height, so as to
bear the load stress of large vehicles.
3. Reinforcement of subgrade fill behind abutment: geocell can
better realize the purpose of abutment back reinforcement. Enough
friction force can be generated between geocell and filler, which
can effectively reduce the uneven settlement between subgrade and
structure. Finally, it can be effective and slow to solve the early
impact damage of bridge deck caused by "abutment bump" disease.
4. Subgrade in Permafrost Regions: when constructing fill subgrade
in permafrost regions, the filling height should reach Zui small
filling height, so as to prevent frost boiling or the upper limit
of frozen layer from falling, resulting in excessive settlement of
embankment. Geogrid has the effect of vertical reinforcement and
effective implementation of the overall lateral limit, which can
largely ensure the height of small fill in some special sections,
and make the fill have high-quality strength and stiffness.
5. Treatment of loess collapsible subgrade: for expressways and
class I and class I highways passing through collapsible loess and
loess section with better compressibility, or when the allowable
bearing capacity of high embankment foundation is lower than the
pressure of vehicle cooperative load and embankment self weight,
the subgrade shall be treated according to the bearing capacity
requirements, and then the superiority of geocell is obvious.
6. Saline soil, expansive soil: Highway constructed by saline soil
and expansive soil, highway of first class, road shoulder and slope
are reinforced. The facade reinforcement effect of the cell is one
of the excellent reinforcement materials, and it has excellent
corrosion resistance, which can fully meet the requirements of high
highway construction in saline soil and expansive soil.
