Камнепады, обвалы, осыпи - Barrage de Cahora Bassa 2022

High-energy deflectors protect the access road to the dam from the risk of a major cliff fall

Камнепады, обвалы, осыпи - Barrage de Cahora Bassa 2022

Installation of the deflectors is greatly facilitated by the use of SPIDER S4-130 nets, packaged in rolls and offering an unbeatable weight/resistance ratio

With its 7-meter posts, the upper part intercepts the falling blocks and brings them down to the “drape” part of the barrier - an effective system for high-frequency rockfall

Ситуация

The Cahora Bassa dam, on the Zambezi River, has a total storage capacity of 65 billion m³, making it the 4th largest artificial lake in Africa. Thanks to the 171-meter-high, 303-meter-long arch dam, its hydroelectric power station generates up to 2,075 MW, making it the 2nd most powerful in Africa. The spillways and the only access road to the plant are located below the cliff. Recurrent landslides have led the plant’s owner, Hidroelectrica de Cahora Bassa (HCB), to reinforce the cliff.

Описание
