High Strength Plastic Geocell
The high-strength plastic geocell is a new type of soft foundation reinforcement and slope treatment engineering products. It is made from high-molecular polyethylene by strong welding and formed into a honeycomb structure.
The tensile test results show that the shear strength increment of geocell is highly dependent on its pocket diameter and aspect ratio. A smaller pocket size and higher aspect ratio can result in an increased shear strength.
Light in Weight
Compared to other traditional materials like stones and soil, plastic geocell is light in weight. It also has a high compressive strength, good wear resistance and is easy to clean. These features make it ideal for use in construction projects. Plastic geocells can also be easily expanded to accommodate a variety of different needs.
The main use of plastic geocells is to provide support for roads and other paved surfaces. They can help to prevent ground shifts and erosion over a long period of time. They can also help to stabilize sloped grounds, so they do not move as much during heavy traffic. This will protect the road and save money in the long run by reducing costly repairs.
Another important benefit of using plastic geocells is that they are highly effective at preventing erosion in sloppy terrain. They are able to protect and stabilize the area, which will reduce erosion caused by storms or rain. This will also protect the environment and people in the area.
The rhomboidal indentation texture on the surface of the geocell creates friction that helps to keep fill in place. The perforation pattern on the surface of the geocell allows water to move freely through the product without washing out the fill, ensuring that it stays in place and improving the structural integrity of the soil. For the best results, we recommend putting a non-woven or woven geotextile under the geocell for separation, reinforcement and weed control.
Good Lateral Restrict
Plastic geocell for slope protection are made of a special three-dimensional mesh that is widely used in subgrade, side slope, and retaining wall engineering [3,4,5]. The lateral confinement of the cells helps to prevent soil spreading, which can significantly improve stability. Geoweb geocell is easy to expand, which makes it a great choice for projects with changing soil conditions.
Geocell strips are primarily made of high-density polyethylene (HDPE), polypropylene (PP), or polyester (PET) and are extruded through a process of forming, High Strength Plastic Geocell stretching, folding, and welding. The strips are cut into different designs and shapes to fit the project requirements, then heated, welded, and compressed to form their shape. The geocell’s dimensional stability and mechanical properties are greatly improved by this process.
The tensile test of geocells at different temperatures has been performed to study the effects of low temperature on their mechanical behavior. It was found that the tensile test results of HDPE strips were not significantly affected by low temperatures, while those of PP and PET geocells showed a strong influence.
In addition, HDPE geocells have a geogrid high ductility, which makes them a good choice for cold areas. This property also allows them to be used for applications such as railway track ballast. Moreover, they have a high lateral stiffness limit and can be used for projects with varying soil conditions. They are also resistant to wear, chemical stability, light oxidative aging, and acid.
Easily Expandable
Plastic geocell is easy to use and can be expanded in a wide variety of applications. It can be filled with soil, aggregate or recycled materials to reinforce a subgrade layer. Its three-dimensional honeycomb grid design restrains soil laterally and improves shear strength and load-bearing capacity. This helps reduce pavement failures, and is a useful tool in mining containment, slope erosion control and rock-based construction.
This material is environmentally sustainable, as it reduces the need for excavation and saves on expensive labor costs. It is also available in a range of heights, with 3″ being ideal for pedestrian traffic, and 4″ and 6″ for heavy-duty applications such as driveways and overflow parking areas. The 6″ version is also suitable for industrial traffic gravel roads, airport runway and taxiways, railways, and steep slope erosion control.
The mechanical properties of geocells are sensitive to temperature, so a good understanding of their behavior is required. This is particularly important in cold area engineering, where the tensile strength of the geocells may be affected by ambient temperatures. To study the effect of temperature on the tensile properties of geocells, samples of HDPE, PP, and PET were subjected to uniaxial tensile tests at ambient temperatures of -5 degC, -20 degC, and -35 degC. The elongation of the geocells at the time of failure was determined and the results were compared.
Made from Recycled Materials
Geocells can be made from a variety of materials, but the most popular are high-density polyethylene (HDPE) and plastic waste. These materials are used to reinforce slopes and prevent rutting, erosion, and soil movement. They are also a green construction solution because they are made from recycled materials.
The production of HDPE geocells involves several stages, starting with the extrusion of the plastic. Then, the sheets are cut into specific designs and shapes for use in the construction process. The sheets are then welded together using the high-power ultrasonic. This is the process that gives the geocell its unique three-dimensional honeycomb structure.
Once the panels have been welded together, they are filled with soil or other fill material. These materials are then pressed into the cells of the geocell, creating a strong and resilient confinement system. This cellular confinement system increases the strength and lifespan of the pavement layer or holding structure.
Various infill materials have been tested for their effectiveness in geocell-reinforced slopes. These include sand, crushed aggregates, and recycled asphalt pavement (RAP). Compared to sand, crushed aggregates have a higher load-bearing capacity and reduce settlement and surface sheave. However, the best infill for a geocell depends on the project’s needs and desired outcomes. Other potential infill materials include jute, bamboo, and seashell. These infills are also effective in reducing lateral sheave and heave.
