Access Tunnels:
T&H are currently doing a study on turning radius and tunnel dimensions required.
MRO request a 25 m turning radius, or whatever T&H request, whichever is larger.
Same ceiling dimensions for robotics reserved space in the tunnels: 2.9 m wide by 0.55 height
Wide sections of main tunnel
Concerns raised about the long straight sections which have widened areas that would require crane access and may limit placement of the rails.
The models on PLM are most up to date and should be used by MRO to investigate.
A review of tasks that need to be performed in the long straight sections should be made by MRO and thoughts given to how the rails can fit in the wider tunnel.
Parking Space in Service Caverns
Max space of 230 m^2 would be difficult to achieve.
Vertical concept is preferred option.
Floor seperation undecided in caverns, but could be as high as 6 m, which could be suitable for vertical stacking.
Horizontal parking is less efficient due to tracks needing 90 degree bend.
Space beneath the bends does not need to be reserved, but ideally will not have fixed equipment beneath. E.g transport vehicles are fine to park beneath.
Final proposal:
Round to 150 m^2 floor space (10 x 15 m) by 8 m height reserved
Considerations to be made for rail curvature access to parking. (i.e angled parking or a
Crane access
Robots need to be transported from surface. It can be done with forklift, if they can access the lifts, but an overhead crane would be easier once in the cavern.
Alcove Chicane dimensions
The dimensions of the paths for the robot to access the alcoves are requested to be 1.5 m wide.
It was noted that the chicane concepts do have sliding concrete walls that allow for T&H access directly to the chicane. As this is the case, the 1.5 m wide corridors do not need to apply to the chicane, as long as under normal shut down operations, the robot will have a 1.5m wide route to the main tunnel.
