Hdpe Retaining Wall Geocell Confinement System 1.1mm-1.8mm

Smooth/Textured Perforated Plastic HDPE Geocell for Retaining Wall 1.1mm-1.8mm

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 three-dimensional mesh cell structure formed by high-strength welding of REINFORCED HDPE sheet material. It is generally made by ultrasonic needle welding. Due to engineering needs, some holes are punched on the diaphragm.

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

Soft soil foundation reinforcement, retaining wall and pavement anti crack engineering of highway, railway, abutment, approach road, wharf, dam, slag yard, etc.
Engineering function:
1. It has high strength, low creep and can adapt to all kinds of environmental soil, which can fully meet the use of tall retaining wall in high-grade highway.
2. It can effectively improve the interlocking and bite effect of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrict the lateral displacement of the soil, and enhance the stability of the foundation.
3. Compared with the traditional grid, it has the characteristics of high strength, strong bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform holes, convenient construction and long service life.
4. It is more suitable for deep-sea operation and embankment reinforcement, and fundamentally solves the technical problems such as low strength, poor corrosion resistance and short service life caused by long-term seawater erosion of gabions made of other materials.
5. It can effectively avoid construction damage caused by rolling and damage by machines and tools during construction

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.
