Stabilization of slopes in order to build embankments for a bridge
The construction of a highway bridge can lead to the creation of highly inclined slopes that consist of local sand.
Deformations of the base occur for various reasons, including due to:
- design errors;
- violations of construction technology;
- lack of drainage from the embankment;
- increased traffic intensity;
- increasing project loads and unforeseen anthropogenic situations.
There are two ways to solve the problem – through concrete walls, which are too expensive and disfigure the landscape; or you can create steep slopes that require a very large surface. In addition, even in this case, it’s necessary to use very expensive materials that are difficult to seal due to the slope, which can lead to the risk of landslides.
The new method and its advantages:
- Тhe technology – simple, durable, environmentally friendly and economical.
- To stabilize the slopes, the cells of the geogrid can be filled with local vegetative soil or other material to limit the effect of erosion and ensure the stability of the base on the road.
- The geogrid allows the vegetation to develop in harmony with the landscape.
- Once the tools are firmly attached to the top of the slope, near the asphalt, the filling is poured directly from a truck. Some of the cells are planted manually with seasonal or permanent plants.
After a short time the slope is covered with vegetation, which makes the terrain stable and prevents erosion. It has been shown that even for a long time after the installation of the cells, it’s practically impossible to distinguish the retention system, as the whole slope is covered with abundant vegetation of different species.
