How They Work Together in Tunnel Support
1.Excavation
2.Rock scaling / cleaning
3.Bolting trolley drills holes + installs bolts
4.Wet shotcrete machine sprays primary lining
5.Optional: Steel arch installation & mesh reinforcement
6.Cycle repeats
This forms a continuous support process for safe advance of the tunnel face.
Wet shotcrete equipment + rock bolting trolleys =
✔ fast covering support
✔ strong internal anchorage
✔ safe, efficient tunnel advance
They are indispensable in nearly all modern tunnel and underground construction systems.
