PIPE UMBRELLA
Pipe Umbrella Systems for Tunnelling and Ground Stabilization
Pipe Umbrella systems are pre-support systems used in tunnelling and underground construction to improve stability ahead of excavation.
The system consists of a series of steel pipes installed around the excavation perimeter to create a reinforced canopy ahead of the tunnel face.
Applications
Pipe Umbrella systems are particularly useful for:
- Tunnelling
- Weak ground
- Fractured rock
- Unstable geological formations
- Tunnel portals
- Shallow tunnels
- Underground infrastructure
- Areas requiring pre-support
Advantages
- Provides pre-support ahead of excavation
- Helps control ground deformation
- Suitable for weak and unstable ground
- Supports staged tunnel excavation
- Can be integrated with other tunnelling support systems
