Here's why:
🔧 Key Functions in Tunnel Construction:
Rock Support:
Wet shotcrete forms a protective layer over the tunnel surface, stabilizing loose rock and preventing collapses.
Fast Application:
It allows for high-speed spraying of concrete, which is crucial in maintaining construction schedules.
Dust Reduction:
Compared to dry shotcrete, the wet process generates less dust, improving worker safety-especially in enclosed environments like tunnels.
Better Bonding and Strength:
Wet shotcrete generally provides stronger adhesion to rock surfaces and has better curing quality, making the tunnel lining more durable.
Works with Robotic Arms:
Modern machines often use robotic spray arms, improving accuracy, coverage, and safety-especially in large or irregular tunnel sections.
