High Strength Plastic Geocell
High Strength Plastic Geocell is a powerful reinforcement for road construction. It’s able to maintain a large amount of pressure, even from military-grade vehicles.
The tensile strength of HDPE, PP, and PET geocell strips has been investigated. The results show that the tensile behavior is influenced by temperature. The ductility is also affected.
Durability
High strength plastic geocell is a great choice for use in road construction. It can be used to stabilize roads built on unstable soils such as sand, peat bogs and expansive clays. It can also be used in other soft foundation treatment applications.
The geocells are made of PP, PET or HDPE as raw materials and they are designed to be strong and durable, with a low elongation. The elongation of a geocell is determined by the rib’s strength and the cell height. It is recommended that the elongation of a geocell be greater than 20 percent of its tensile strength to ensure adequate performance.
A geocell’s ability to resist seismic excitation is a measure of its structural long-term performance. Static plate-load tests conducted on a shake table at the Japan National Research Institute of Agricultural Engineering, Tsukuba City, have shown that the geocell retention systems can withstand gross maximum payloads of 500kN without permanent deformation or excessive vibration.
In addition, a series of tests on the geocells’ ability to restrain soil laterally has shown that they can increase the strength and resilience modulus of poorly-graded soils [10]. These results demonstrate that hoop stresses in the geocell walls can reduce plastic deformation and improve the load-deformation and stress distribution characteristics of the underlying soil. They can also enhance the confinement effect of poorly-graded materials and promote active wedge formation.
Strength
A geocell’s strength stems from the tensile and flexural properties of the material it is made from. This allows the geocell to distribute loads evenly across a surface and minimize stress on weak layers. Moreover, it also provides a stable base for construction and reduces the impact of differential settlement. In addition, it can prevent erosion by preventing the movement of soil particles into the paved area.
Geocells are available in different sizes High Strength Plastic Geocell and materials, including polyethylene, high-density polyethylene, woven polypropylene and fiberglass. They are also injected with additives such as HALS (Hinderred Amine Light Stabilizers), which prevents the degradation of the geocell by exposure to heat and direct sunlight.
The tensile properties of geocell strips vary with temperature. The tensile strength of a strip decreases as the temperature drops. This explains why geocells are widely used in cold regions. The tensile strengths of HDPE, PP, and PET geocell strips were studied by means of a tensile test Geosynthetic clay liner machine. The results of this test indicated that the tensile strength of the HDPE strip was the lowest, followed by PP and PET.
Another way to measure the strength of a geocell is through Dynamical Mechanical Analysis (DMA). The DMA tests the net elastic modulus of a polymer. A low net elastic modulus is not good for a geocell system because it would mean a loss of confinement and failure of the structure.
Versatility
A geocell is a versatile and durable construction material that has many uses. It can be used for a variety of applications, including erosion control, ground stabilization, and load support. It can also be used for retaining wall facings and slope protection. These benefits make it a popular choice for infrastructure and construction projects. Geocells are also lightweight, making them easy to transport and install.
The manufacturing process of plastic geocells begins with the extrusion of sheets into different shapes and sizes. The sheets are then folded into the specific design of the plastic geocell. Then, they are welded together at the contact points. Once this is done, the cell formation is complete. After this step, the geocells undergo a quality check to ensure that they meet construction standards.
Using a geocell under roadbeds helps to increase stability and strength while reducing the amount of aggregate required. It can also help to prevent the lateral spreading of soils. It can be used on slopes and embankments to protect against erosion by rain or snow. Geocells can be expanded to fit a specific area and can be made with perforations to allow for the passage of water, nutrients, and soil organisms. This increases plant growth and improves slope and soil quality. It also allows for better drainage and withstands hydraulic shear stresses.
Environmentally Friendly
The perforations in the geocell allow water to flow through, preventing soil compaction. This is important because it prevents the ground from becoming unserviceable, which can reduce its lifespan and lead to costly repairs. It also increases the stability of slopes, making them less likely to erode or wash out materials. It is a cost-effective way to retain earth and water, making it an excellent choice for use on road construction projects.
Plastic geocells are also eco-friendly. They are made from recycled materials and are themselves recyclable, minimizing their environmental impact. Additionally, they can be expanded and contracted as needed to fit the terrain of a project site. This makes them ideal for landscaping, channel protection, and structural reinforcement.
Compared to traditional construction methods, using geocells can increase the efficiency and speed of road construction. They can be used to stabilize a variety of structures, including highways, railways, and bridges. They can also be used in coastal areas and to reinforce landfills.
In addition to being environmentally friendly, plastic geocells are easy to install and require little training and know-how to set up. They are also lightweight, allowing for fast transportation and installation. This saves on construction costs, labor, and equipment. Furthermore, they are resistant to physical wear and chemical degradation, ensuring long service life and limiting the need for regular maintenance.
