Shield Tail Brush
A Shield Tail Brush is a specialized tool used in Tunnel Boring Machines (TBMs) to clean and seal the shield's tail section.
A Shield Tail Brush is a specialized tool used in Tunnel Boring Machines (TBMs) to clean and seal the shield's tail section. Positioned at the rear of the TBM, the shield tail brush is designed to prevent soil, water, and debris from entering the machine's tailskin while maintaining a consistent pressure environment for optimal performance. This tool is essential for keeping the tunnel excavation clean and preventing clogging or operational issues caused by material buildup.
Key Functions:
- Cleaning & Sealing – Effectively brushes and seals the rear end of the TBM shield, ensuring a clean passage for the material flow.
- Debris Prevention – Prevents loose soil, water, and debris from entering the TBM’s tailskin and causing clogging or operational disruptions.
- Maintains Internal Pressure – Ensures the TBM’s tail area remains properly sealed, maintaining necessary pressure for smooth excavation.
- Durability – Constructed from high-strength, wear-resistant materials such as stainless steel or specialized brush fibers, designed for long-lasting use in demanding tunneling conditions.
- Easy Maintenance – The brush allows for quick cleaning and replacement, minimizing downtime during operations.
