Light Material Resistant To Wear Textured High Strength Cellular Confinement System

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.

Characteristics of geocell:

1. It can be stretched into a net during construction, and filled with loose materials such as soil, gravel, concrete, etc. to form a structure with strong lateral limit and large rigidity.
2. Light material, wear resistance, chemical stability, light and oxygen aging, acid and alkali resistance, suitable for different soil and desert soil conditions.
3. Higher lateral limit, anti-skid, anti deformation, effective enhancement of subgrade bearing capacity and dispersive load.
4. The change of geocell height, welding distance and other geometric dimensions can meet different engineering needs.
5. Flexible, small transportation volume, convenient connection and fast construction speed.

Application of geocell:

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.
