Brief Introduction of Geocell Confinement System

Geocell Confinement System--also known as Cellular Confinement System(CCS), 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.

What is Geocell?

The project is mainly applied to slope protection in civil engineering fields such as highway, railway and hydropower, treatment of weak foundation of highway and railway, and prevention and control of vehicle jumping at the bridgehead of highway bridges.
It mainly controls the uneven settlement of the subgrade filling and excavation junction or the junction of new and old subgrade; The design method and construction technology of ecological slope protection and ecological retaining wall of subgrade slope, flexible raft foundation and pile raft composite foundation are put forward; Study the design and construction of abutment wedge-shaped flexible approach slab technology;

Geocell Confinement System Characteristic

Geocell is a new type of geosynthetics in the world in the 1980s. This is a three-dimensional network structure made of wide strips of high molecular polymer through strong welding. It can expand and contract freely. It can be folded during transportation and opened during use. It is filled with sand, gravel or soil in the cell to form a structure with strong lateral restriction and large stiffness. It can be used as cushion to improve the bearing capacity of soft foundation, and can also be laid on the slope, It forms a slope protection structure and can also be used to build a retaining structure. At present, it is widely used in shallow foundation treatment, slope erosion prevention and urban large-scale pipeline support. It is a promising basic engineering construction material.

Application

Once the load acts on the subgrade, a wedge-shaped active area will be formed under the load, which will be squeezed through the transition area, so as to uplift the passive area. In other words, the bearing capacity of the foundation is determined by the shear force along the slip line and the forces moving the active, transition and passive areas. The real process of the above principles can be clearly realized not only on the sand base, but also on the soft foundation highway, but its formation rate is slower than that on the sand. Even better subgrade materials cannot avoid lateral movement. General highway subgrade is several meters higher than the ground, so it is not easy to absorb water and churn, but long-term settlement still exists. The reason is that rainwater infiltration, material loss and base subsidence are some of the reasons. Under the action of long-term rolling and vibration force of wheel load, the lateral displacement of materials to both sides of subgrade section is undeniably another very important reason. Taking highways at all levels in our province as an example, it can be clearly felt that the pavement has been pressed out of an "s" shaped ditch belt on the main carriageway of the road. Some expressways are no exception. The bumping of cars on the carriageway is obviously stronger than that on the overtaking belt, especially in the road bridge connection section (commonly known as "bridgehead jumping"). This kind of ditch subgrade settlement is a typical example of lateral slip of subgrade materials.

Laying method

Construction method of geocell:
1. Broken surface leveling: the flatness of slope surface is related to the success or failure of grass planting protection in geocell. When the slope surface is uneven, the laying of geocell is easy to produce stress concentration, resulting in cracking of cell solder joints, resulting in cell stepping, etc. Therefore, the slope must be leveled to the design requirements, and the slope shall be repaired manually to remove the pumice and dangerous stones on the slope.
2. The main drainage ditch system shall be set on the side slope of the paved cell: a distance of 4m shall be maintained between two adjacent ditches, and the drainage ditch shall be connected with the highway side ditch, so that the road area water flows into the drainage channel along the side ditch and into the edge of the highway, so as to prevent the road area water from scouring the cell slope protection.
3. Laying direction: the cell shall be laid from top to bottom in the main stress direction to make the cell sheet perpendicular to the highway subgrade. Never lay horizontally.
