Tunnel energy storage coating construction plan

What is a complex tunnel system?

Complex tunnel system: The underground components can become extremely complex with the powerhouse cavern, waterway tunnels and shafts, drainage galleries, manifolds, surge facilities, and access tunnels. With the powerhouse usually being on the critical path, access tunnels to the powerhouse need to have the quickest access.

Why should a powerhouse be near a waterway tunnel?

For performance and economic reasons, the powerhouse should be close to the mid-point of the waterway tunnel system. This shortens the high-pressure tunnels but also makes the water in the tunnel more stable for quickly starting and stopping.

Why do powerhouses need access tunnels?

With the powerhouse usually being on the critical path, access tunnels to the powerhouse need to have the quickest access. Other elements need construction access tunnels to not interfere with the powerhouse construction. Integrated team: Everything affects everything.
