Geocell Slope Protection
Geocell structures combined with planting vegetation provide a soil treatment method to protect slopes from erosion and offer a fostering environment for plant growth. This study aims to evaluate the performance of the geocell slope protection system by analyzing the development of slope failures, soil erosion and surface displacement.
Different sized geocells were used to reinforce the slope models and the effect of the size on the slope stability was assessed. The results showed that small geocell-reinforced slopes have less measured soil erosion and displacement than unsupported slopes.
Strength
Erosion is a common problem on sloped grounds and can lead to soil movement, which in turn can cause serious damage to the environment. The use of geocells can help to prevent erosion by stabilizing the ground and soil. These structures are made from high-density polyethylene material and can be installed without the need for heavy equipment. They are also environmentally friendly and can be reused over time.
One of the most important benefits of using a geocell for slope protection is that it can improve the strength and stability of the soil. This is because the cellular confinement system walling off and confining soil particles increases the frictional force between the soil and the cell walls, which prevents movement and reduces erosion. The confined infill material also produces lateral strain on the edges of the cells, which helps to stabilize the soil and prevent landslides.
In this study, nine experiments were conducted to investigate the soil erosion and slope displacement for different support strategies and rainfall intensities. The results show that the unsupported slope shows the most severe erosion during the rainy period. It is because the surface soil is scoured and forms a number of horizontal fractures filled with water. On the other hand, the geocell and wheat straw composite reinforced slopes have good stability during the rainy period.
Stability
In addition to improving the tensile strength of sloped areas, geocells also increase their stability by preventing soil movement. They build a three-dimensional wall that prevents soil Slope Protection Geocell Used particles from moving laterally, which helps prevent landslides and keeps the area safe for use. This can be particularly beneficial for structures that have to work on a sloped surface, like railroads or roadways.
Unlike conventional slope stabilization methods, which can damage the environment, TYPAR geocells are non-toxic and environmentally friendly. They also do not require heavy machinery to install them, which reduces the project’s environmental footprint. This is why TYPAR geocells are becoming increasingly popular for slope protection and stabilization projects.
The cellular confinement system of geocells is permeable to water, air, and nutrients, which makes it a great choice for green infrastructure applications. They also have a high load-bearing capacity and are capable of supporting a variety of infill materials. These benefits make them an excellent alternative to gabion and other more expensive slope protection options.
Studies have shown that despite their small size, geocells are very effective in protecting the slope against erosion. For example, a study by Dash et al. (2003) found that when compared to the unsupported slope, the geocell- and wheat straw-reinforced slopes experienced significantly less soil erosion. The decrease in erosion is attributed to the fact that the slopes’ geocell and wheat straw structures slow down the penetration of rainwater into the soil.
Displacement
As the soil is being compacted inside the geocell, it creates lateral stresses and resistance to movement. This helps Composite Drainage Network to stabilize the slopes and protects the underlying soil. This makes them more useful than traditional construction or mechanical methods of stabilizing slopes.
Geocells are made of flexible cellular walls that confine and retain soil, aggregate, or other infill materials, controlling slope movements and slippage due to hydrodynamic and gravitational forces. They also limit erosion and help to build sustainable infrastructures. Unlike other traditional construction methods, these cellular confinement systems allow for a variety of infill materials like gravel and soil.
The displacement of the slopes increased over time, but this increase slowed down after the rainfall stopped. The unsupported slope showed the highest displacement, followed by the geocell-reinforced slope and the slope with a geocell and wheat straw composite.
The results indicated that a larger geocell size is more effective in increasing the slope stability than a smaller one. This is because a large geocell increases the tensile stiffness, thereby increasing the slope stability. It is important to note that the tensile stiffness of the geocells is also dependent on the type of infill material used and the soil. These factors can be controlled by the design of the slope and the infill material. In addition, a geocell wall that is connected to a micropile can provide additional support for the infill and improve the overall slope performance.
Water Retention
Geocells are great for reducing erosion, especially in places where you need to stabilize the ground. They can help stabilize structures like railroads, and they can also prevent erosion on roads and walkways. This is one of the main reasons they are so popular, because erosion can cause a lot of damage, and it can also be dangerous for people.
These cells can also be used for channel linings. They can be filled with gravel or soil, and they will help to keep the dirt in place. They will also allow water to flow freely, so they can be used in a variety of different ways.
Another thing that these geocells do is that they will help to increase the stability of slopes. They do this by increasing the resistance to erosive forces, and they will also protect the roots of vegetation. These cells can be used in different sizes, but they are best for slopes with low-to-moderate flows.
If you are using these geocells for slope stabilization, it is important to choose the right type of soil to fill them with. You should try to use local planting soil as much as possible, and you should avoid soil that is mixed with gravel or stones. This will help to keep the cost down, and it will also be better for the environment.
