Geocell for Roadbed
Heavy load roads require a strong foundation. That’s where Geocell for Roadbed comes in.
The cellular confinement of geocells reduces soil particle lateral movement while increasing shear strength. This helps stabilize the subgrade and prevent settlement and rutting during construction.
In addition, the honeycomb-like cells distribute loads evenly across a larger area, reducing stress on foundation soil and extending the life of the roadway.
Stabilizes Subgrade
Geocells are an easy and cost-effective way to stabilize the subgrade, increasing its load bearing capacity. The cellular confinement that a geocell provides mitigates the radial and vertical settlement of aggregate and soil, making them a valuable solution for road construction. Additionally, the cell structure of a geocell provides uniform stress distribution throughout the subgrade, preventing surface and structural failures.
A geocell is a three-dimensional network of honeycomb cells filled with soil or gravel, which can be used to stabilize slopes, improve the load bearing capacity of roads, and prevent erosion. Geocells can also be utilized to reinforce pavement structures, reduce the rutting of asphalt roads, and prevent cracking of foundation soils.
On site, the geocell is laid out over the roadbed and fastened with anchors or buried in a concrete base. The sections of the geocell expand out in an accordion-like fashion, covering a large area and consisting of hundreds of individual cells. The cells can be filled with a variety of infill materials such as soil, sand, and aggregate to provide a wide range of stabilization properties.
It has been shown that the cellular confinement of a geocell significantly increases the modulus of subgrade reaction and the Geocell for Roadbed ultimate bearing capacity of lime-stabilized soil. A geocell-reinforced soil also exhibits lower plastic deformation than unreinforced soil, and the one-third frequency curve of the vibration is significantly attenuated over larger horizontal distances.
Increases Load Bearing Capacity
As a kind of special geosynthetics, Geocell has good load bearing capacity and can effectively disperse the load. It has a high lateral limit and offers anti-skid and anti-deformation properties, enhancing the support ability of the roadbed and improving its overall safety. It can be used in different construction environments, such as roadbeds, railways, slopes and walls, and mining.
Geocell is a three-dimensional flexible material that can expand and contract, which makes it ideal for use in difficult conditions. It can also be adjusted to fit a variety of engineering needs by changing the height and welding distance. Because of this flexibility, it can be easily transported and assembled.
The unique structure of Geocell for Roadbed helps reduce the amount of aggregate needed during construction. This means that roads can be constructed more quickly and at a lower cost. It also improves the strength and durability of roads.
The use of geocells also increases the vibration resistance of the aeolian sand roadbed. This is measured using the equivalent amplitude, which is more comprehensive than the maximum amplitude. Moreover, the results indicate that the performance of geocell-reinforced aeolian sand is much closer to that of gravel soil than unreinforced gravel soil. This is primarily due to the fact that the geometric dimensions of the cells are very similar to those of gravel soil.
Prevents Rutting
With its unique structure, Geocell for Roadbed is an effective solution to stabilize the soft soils of roads. It decreases the labor intensity of engineering construction, reduces the thickness of roadbed subgrade, and helps speed up the construction speed, thus reducing the project cost. It also increases the bearing capacity of the roadbed foundation, and protects the embankment from collapsing. It is suitable for the reinforcement of various highways, first-class highways, railways and other permanent bearing foundations.
It is made of a wear-resistant and stable polypropylene resin material, resistant to acid and alkali, and light in color. It is also compatible with different soil conditions and deserts. The lateral limit structure of the geocell can prevent the movement of loose soil particles during trafficking, improving the load distribution and increasing the bearing capacity of the roadbed foundation.
Use J-hook rebar anchor stakes to secure the Geocell to the ground before filling with aggregate and compaction. The anchor stakes hold the Geocell in geogrid supplier place and ensure that it does not work itself upwards over time, allowing you to save on fill material costs. Use a gravel size that matches the original road design, ensuring the infill is evenly distributed and compacted. This step is especially important for roads with traffic as it helps reduce the “quicksand effect”. Also, a textured surface on the Geocell adds additional material retention, making them perfect for slopes and embankments prone to erosion.
Prevents Erosion
When used under road construction, Geocells help stabilize slopes and prevent soil displacement. They also improve the load-bearing capacity of weak subgrade soils, thus extending the life of the roadbed. Additionally, the honeycomb structure of the cells distributes the weight over a wider area, reducing localized pressure on the foundation soil. This helps reduce settlement and cracks in the road surface.
In general, Geocells have a high elastic stiffness and tensile strength. This makes them a perfect choice for intense load support applications. They are especially well-suited to roads with a high dynamic stress, like those that must withstand the passage of heavy vehicles. They can support a wide range of vehicles and are very durable, even when subjected to constant, long-term loads.
Aside from its load-bearing capability, the geocell’s cell structure also improves drainage and promotes vegetation growth in the area. This is particularly beneficial in areas prone to flooding or other natural disasters. However, the geocell’s cost, complexity of installation, and weight must be considered in order to determine whether it is appropriate for a particular project. In addition, geocells are less available than many other materials. For this reason, it is important to plan ahead for any commercial project that requires the use of geocells. This will ensure that the project is completed on time and within budget.
