CONSTRUCTION OF CONTAINMENT WALLS
The retaining walls are used for the stabilization of inclined terrains, where normally the detachment of materials occurs, they retain the body of embankments with high inclination, thus avoiding the displacement of the materials. Sometimes the retaining walls serve not only for fixing the slopes but also for laying the road.
In the strengthening of slopes and hillsides, “GeoFRAM” is used as a permanent element, mainly fulfilling a protection function, and serves as:
• Filling to slow or prevent water and wind erosion.
• Reinforcement to improve the stability of the slope surface.
• Filter to prevent the loss of soil particles because of groundwater and precipitation.
In the strengthening of slopes with unstable terrain, slopes of considerable height and inclination of 45 ° or more, it is preferable to resort to retaining walls. The need for the construction of such structures arises in the construction of roads, bridges, viaducts and other structures, as it helps to retain the soil.
The retaining walls also serve for the construction of roads, since they constitute an important part of the embankment.
The retaining walls made with “GeoFRAM” filled with absorbing materials are more cost-effective and easy to install and increase their efficiency. Soils reinforced with retaining walls are better adapted to soil irregularities.
STEPS TO FOLLOW FOR THE CONSTRUCTION OF A WALL OF CONTAINMENT
In the photomontage you can observe the construction of a retaining wall in the area with problems of detachment of the land. The important thing is that the upper part is a path for the passage of vehicles. We solve this problem using our GeoFRAM geosynthetic structures.
First, we prepare the ground for GeoFRAM placement, and for that we remove the existing absorbing materials, which we will use later to fill the GeoFRAM cells.
Once the base is prepared, we will place the three-dimensional GeoFRAM structures sequentially, and in order to maintain the shape of these structures and facilitate their filling, we will place a metal frame in them, which will be extracted once we have GeoFRAM filled with the same absorbents removed previously.
Next, we go on to compact this base with compactors. This process will be repeated in the successive upper layers, until finally reaching the retaining wall.
