Prolonged and intense precipitation provokes rising water levels in rivers, soil erosion in mountainous areas, which leads to soil destruction, landscape disturbance, and the destruction of buildings and homes. This problem is especially relevant in Western Ukraine, where thousands of people suffer from floods every year. What is the way to use to prevent the terrible effects of bad weather? Strengthening the soil with gabions.
Why choose gabion structures? After all, without huge costs with their help you can strengthen the buildings. Where will reinforcement be appropriate? Used at the foot of rivers, from the blurring of embankments, soil rocks, races, bridges, slopes. Gabions perform their functions due to the specific structure of the metal base. The sections of the rods are quite dense, so in contact with the surface are held in place. The structure can be in one position for more than 100 years without the need for replacement and reconstruction, which is very important in shore protection. The basis for gabions is a double twist grid. The metal construction complies with TU and GOST standard, additionally coated with zinc, to prevent corrosion due to the influence of a constant humid environment.
In what cases strengthen the soil with gabion structures? If the slope or slope:
- is under a high degree;
- located on a site with loose soil;
- prone to regular leaching by water currents;
- prone to rock falls;
- washed by the fast flow of the river;
- is located on wetlands;
- at the foot is a ditch;
- is located above a railway or highway;
- located in front of a private or country plot;
- designed to strengthen the soil under the bridge.
Stages of installation of protective gabions:
1. Preparatory work
First, clean the ground of plant roots, stones and debris. Next, level the soil so that the gabions do not sag due to the heavy weight of the filler. Use the method of embankment or removal of excess soil, leveling the area to the average value.
2. Installation of a design
Installation of gabion protective structures such as: Renault mattresses, jumbo, retaining wall or therramesh system. The type is chosen depending on the surface area to be strengthened and the scope.
3. Filling
Fill the structure with rubble or rubble.
Strengthen river banks and slopes with gabion structures to prevent the unpleasant consequences of natural disasters. After all, it is relatively inexpensive, and its installation procedure is not time consuming and resourceful.
