Conveyor augment and 3D x-ray illustration

The foam and concrete construction of the dome will extend into the small, protruding augment. When complete, the inflated end is cut off and the finished, reinforced opening will be used for the loading conveyor. This x-ray illustration of the finished structure shows how the product nearly fills the entire structure. AC equipment on the tunnel actively maintains a cool, dry climate inside the dome, reducing caking and corrosion.
