Ende transmisión implements emergency work successfully in Structure 25 line 230 KV Santivañez – PAGADOR

The intense registered storm rainfall, have caused the exceptional increase of Waterflow of the Tapacarí River (confluent from the Rocha River), in the Department of Cochabamba, in the charamoco town near the Capinota population, they provoked untimely erosion and undermine of the river margin, leaving the foundation of the structure 25 of the transmission line 230 kv sanctivañez – payer, in addition to damage to the Way access to the structure.

Maintenance staff of transmission transmission lines of operations and Endere maintenance (GOM) transmission, during periodic inspection tasks, They detected that the Foundation of the Pata D was exposed to the erosive action of the river Rocha, evidenced high-risk situation for imminent collapse of Structure 25 and consequent Output of normal operation of the transmission line 230 kV Sanctivates – payer and possible involvement of electricity supply to the population.

Being the mission of Ende Transmission, guarantee the reliability and normal operation of the network of National Electric Transmission, from which the transmission line is part of 230 KV Santáñez – payer, the following emergency work was implemented.

  • Dredge of the river to channel the flow, to take away from the current site of the structure.
  • Filled with selected material in the critical sectors of Erosion of the Margin of Batten, with The purpose of recovering ground and guaranteeing the stability of the paw D and path of access to the structure.
  • Construction of containment structures made up of drawer and mattresses, For the protection of the slope.
