The geocell is a mesh-like cell structure formed by strong welding or riveting of high-strength HDPE or PP copolymer broadband. It expands and contracts can be folded when transported, unfolded when used, and filled with sand, soil, rock, gravel, or concrete to form a structure with strong lateral restraint and high stiffness. It can be used as a cushion to deal with weak foundations to increase the bearing capacity of the foundations, it can also be laid on the slope to form a slope protection structure, and it can also be used to build a retaining structure.
Applications of Geocells
Geocell applied to railway subgrade
Setting the geocell at the bottom of the track bed (the top of the subgrade) can improve the bearing characteristics of the roadbed, reduce the stress of the load transferred to the soil under the cell, and thus reduce the deformation of the soil. When laying geocells in railway subgrade construction, under normal circumstances, the excavation depth of the soft soil of the subgrade bed only needs to be equal to the height of the cell, and there is no need to deepen the side trenches, which can reduce the amount of soft soil excavation. , The construction difficulty is reduced, the construction period is shortened, and the investment is saved.
Geocells are used in the ground foundation treatment of highways, storage yards, and warehouses
When building a highway on a soft soil foundation, the foundation treatment method of replacing the soft soil layer with sand and gravel is easy to cause settlement and deformation, the investment is large and the construction period is long. It can reduce the labor intensity, reduce the thickness of the roadbed, and thus reduce the cost.
Geocells are used in the protection of slopes
When used for slope protection, the unfolded cells form layers of retaining walls, which can ease the water flow velocity and avoid the formation of slope runoff. The compartment can be filled with soil, and grass and shrubs can be planted on it. In the case that the original slope cannot form vegetation, the ideal greening effect can also be obtained, which has an immeasurable environmental protection value. Besides, due to its integrity and certain flexibility, the geocell compensates for the defects of looseness, collapse, and overhead in the protection of the screen skeleton, and is fast in construction and low in cost. It is an ideal geosynthetic material for slope protection.
Geocells are used in retaining walls and cofferdams
Geocells are used to build retaining walls, which have good structural stability and can prevent the surface of steep slopes from being eroded by rainwater. Compared with concrete walls, the cost is reduced by more than 50%. At the same time, flowers and plants can be planted on the surface to beautify the environment.
Geocells are used in road construction in desert areas
Due to the need for prospecting and oil extraction, it is often necessary to build roads in desert areas. In deserts, the foundations are often soft and uninhabited, and the used road construction materials are scarce. Thus, road construction is difficult and costly. The use of earth cells solves this dilemma. The geocell is first pulled apart, fixed on the sand base, and then filled with sand and gravel from local materials. The operation is simple and the efficiency is high. The pavement after construction can meet the long-term use of various heavy-duty trucks.
Geocells for reservoirs and landfills
Geocells provide geomembrane liner protection while creating stable soil, berms, and slopes for slip protection and durable liquid and waste accumulation. Fill treatment depends on the materials involved: concrete for ponds and reservoirs; gravel for landfill drainage and leachate, and vegetation fill for landscape restoration. Since the geocell functions as a ready-made form, the concrete work is efficient and controllable; the geocell and the concrete form a flexible slab that accommodates smaller subgrade movements and prevents cracking. At low to medium flow rates, geocells with geomembranes and gravel overlays can be used to create impervious channels, eliminating the need for concrete.
Sustainable Building
Geocells are a green building solution for making civil infrastructure projects more sustainable. Geocell price concessions, as a geocell manufacturer and supplier, geocell products use 100% new materials, environmental protection, and sustainable development! In load support applications, increased geocell reinforcement can reduce the amount and quality of structural support fill. This means that available but marginal soil types or recyclable materials can be used for construction. This reduces the need for quarry total, which in turn reduces quarrying, transport, and earthmoving equipment. This in turn reduces fuel use, pollution, and carbon footprint, while reducing the built environmental footprint reducing dust, erosion, and runoff. When used in slope applications, perforated Geocell provides plants with an excellent layer of soil protection, drainage, and growth to restore green and vegetated landscapes.
