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?

Geocell is a new type of high-strength geosynthetics popular at home and abroad. It is a three-dimensional mesh cell structure formed by REINFORCED HDPE sheet material and high-strength welding. The utility model has the advantages of flexible expansion, retractable transportation and folding. During construction, it can be tensioned into a network and filled with loose materials such as soil, gravel and concrete to form a structure with strong lateral restriction and large stiffness. It has the characteristics of light material, wear resistance, stable chemical properties, light and oxygen aging resistance, acid and alkali resistance, etc. Due to its high lateral restriction and anti-skid, anti deformation, effective enhancement of subgrade bearing capacity and scattered load, it is widely used in: cushion, stable railway subgrade, stable highway soft foundation treatment, supporting structure of pipeline and sewer, mixed retaining wall to prevent landslide and load gravity, desert, beach, riverbed, river Bank treatment, etc.

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

Geocell has been popularized and applied in China for more than ten years and has achieved good engineering results, especially in the anti-seepage of concrete channel and the projects requiring slope protection and reinforcement such as expressway, river slope and retaining wall. In contemporary subgrade construction, geocell is usually used to effectively prevent the uneven settlement of subgrade. The reinforcement of geocell can effectively reduce the vertical stress and shear force in soil and enhance the stability of subgrade.

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.
