An example of this approach is the erosion recovery project at Tower 100, part of the Evoltz VI transmission line.
Location and Characteristics
- The 230 kV Dona Francisca/Santa Maria transmission line covers 64.35 km in the state of Rio Grande do Sul, crossing municipalities such as Santa Maria, Itaara, and Nova Palma.
- Tower 100,37.5 meters high, is installed in an area of rugged relief and high rainfall, which presented a severe erosive process, compromising the stability of the structure.
Phases of the Work
- Problem identification: An advanced erosive process has been identified at the base of the tower, endangering structural and operational safety.
- Drilling and stapling of the soil for stabilization.
- Application of Concrete Canvas, cement blanket, a pioneer in Brazil for the recovery of erosive processes in the electricity sector.
- Ground cover with concrete, ensuring greater durability and impermeability.
Results and Positive Impacts
- High durability: abrasion resistance 6x higher than standard concrete and life expectancy of more than 100 years.
- Sustainability: 65% reduction in embodied carbon compared to traditional methods.
- Operational efficiency: 50% reduction in the execution time of the work, mitigating associated risks.
