An example of this approach is the Erosion Process Recovery Project at Tower 100, part of the Evoltz VI transmission line.
Location and Characteristics
- The 230 kV Dona Francisca/Santa Maria transmission line spans 64.35 km in the state of Rio Grande do Sul, crossing municipalities such as Santa Maria, Itaara, and Nova Palma.
- Tower 100, standing 37.5 meters high, is located in a region with rugged terrain and high rainfall, which has led to a severe erosion process, compromising the stability of the structure.
Project Phases
- Problem identification: An advanced erosion process was detected at the base of the tower, posing a risk to structural and operational safety.
- Soil drilling and anchoring for stabilization.
- Application of Concrete Canvas, a pioneering cementitious fabric in Brazil for erosion recovery in the electrical sector.
- Soil coverage with concrete, ensuring greater durability and impermeability.
Results and Positive Impacts
- High durability: 6x higher abrasion resistance than standard concrete and an expected lifespan of over 100 years.
- Sustainability: 65% reduction in embedded carbon compared to traditional methods.
- Operational efficiency: 50% reduction in project execution time, mitigating associated risks.
