Tailskin sealing brush
A Tailskin Sealing Brush is a specialized tool used in Tunnel Boring Machines (TBMs) to seal and clean the tailskin area of the machine.
A Tailskin Sealing Brush is a specialized tool used in Tunnel Boring Machines (TBMs) to seal and clean the tailskin area of the machine. Positioned at the rear end of the cutterhead or shield, it helps prevent soil, water, and debris from entering the machine’s internal components, ensuring smooth operation and reducing the risk of damage or clogging. The brush is typically made from durable materials such as steel or rubber to withstand harsh tunneling conditions and provide a reliable seal.
Key Functions:
- Sealing & Cleaning – Helps create a seal around the tailskin area while cleaning debris to maintain the integrity of the TBM.
- Prevents Material Infiltration – Stops soil, water, and other debris from entering the machine, which can interfere with tunneling operations.
- Pressure Maintenance – Contributes to maintaining proper pressure within the TBM, ensuring efficient excavation and reducing the risk of instability.
- Durable Construction – Made from high-strength materials like steel, composite fibers, or rubber to resist wear and ensure a long service life.
- Minimizes Downtime – Reduces the frequency of maintenance by preventing clogging and ensuring that the sealing system remains intact.
