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.

2. Welding distance: 330mm~1600mm
3. Thickness: 1.0mm,1.2mm(smooth), 1.5mm,1.8mm(textured)
4. Appearance/surface: smooth/textured

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

Product features: 1. It can be retracted and folded during transportation. 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. 2. Light material, wear-resistant, stable chemical properties, light and oxygen aging resistance, acid and alkali resistance, suitable for different soil conditions such as soil and desert. 3. High lateral restriction and anti-skid, anti deformation, effectively enhance the bearing capacity of subgrade and disperse load. 4. Changing the geometric dimensions such as geocell height and welding distance can meet the needs of different projects, with flexible expansion, small transportation volume, convenient connection and fast construction speed.

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

Precautions for geocell construction
1. The hole forming position of the anchor rod must be located above the diagonal of the cell to ensure that the cell clock can be transmitted to the anchor rod.
2. The cells must be completely connected with each other to form a piece and connect as a whole.
3. In order to prevent the scouring of water flow on the cell, a waterproof ridge is built on the top of the slope to prevent rainwater from pouring into the cell from the top of the slope and dredge the place where the drainage is not unblocked in time.
