Perforated Ground Stabilization Geocell Confinement System 8mm Hole

High Tensile Strength Perforated Plastic HDPE Geocells for Ground Stabilization

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 mesh cell structure formed by high-strength HDPE broadband and strong welding. The utility model can be retracted freely, can be folded during transportation, and can be opened and filled with earth rock or concrete materials when in use to form a structure with strong lateral restriction and large stiffness. It can be used as cushion to treat soft foundation and increase the bearing capacity of foundation. It can also be laid on slope to form broken surface protection structure, and can also be used to build retaining structure, etc. This material is also very convenient for construction.

Geocell Confinement System Characteristic

1. High strength and small deformation;
2. Small creep;
3. corrosion resistance and long life: steel plastic geogrid with plastic material as protective layer, with various auxiliaries to make it have anti-aging, oxidation properties, acid, alkali, salt and other harsh environment corrosion. Therefore, the steel plastic geogrid can meet the use needs of various permanent projects for more than 100 years, with excellent performance and good dimensional stability.
4. Convenient and fast construction, short period and low cost: the steel plastic geogrid is easy to lay, lap, locate and level, avoiding overlap and intersection, which can effectively shorten the project cycle and save 10% - 50% of the project cost.

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

1. The honeycomb geocell shall be covered during transportation to prevent long-term exposure and pollution;
2. During hot melt welding of honeycomb cell, process experiment shall be conducted before construction. Before the experiment, submit the experiment plan to the supervisor and carry out the experiment after approval. The lap length shall not be less than 10cm, and the lap surface shall not be pulled within 2h after welding;
3. When the tensioning grid is laid flat on the slope surface and the honeycomb geocell is laid, it starts from the slope shoulder and opens along the slope to the slope bottom. The tensioning chamber is placed flat on the slope, and the end slot of the cell is placed in the U-shaped anchor ditch;
4. After the top is fixed, first fix the left and right edges of the tensioned honeycomb geocell grid, and then temporarily fix the bottom opening at the lower end with anchor drill. After filling, pull out the anchor rod used for fixing the lower end;
5. The open honeycomb geocell shall be in a full rhombic shape. It is strictly prohibited to trample or press with heavy objects to cause cell deformation;
6. The filling and burial operation shall be carried out after the honeycomb geocell is inspected to be qualified. The top shall be filled first, and the top U-shaped anchor ditch shall be buried, and then the buried pressure ditch at the slope bottom shall be filled and buried from top to bottom;
7. Humus soil shall be paved on the paved honeycomb cell within 12h for protection, or other protective measures shall be taken to prevent ultraviolet radiation and accelerate the aging of honeycomb cell;
8. After the whole is buried, the soil of one-third of the height of the honeycomb geocell is covered;
9. No paving is allowed in rainy and snowy weather.
