TBM (full section tunnel boring machine) brushes usually refer to the slurry stop brushes or tail brushes in TBM equipment, which are mainly used to prevent materials such as mud and gravel from entering the equipment or causing wear and tear during the excavation process. According to the search results, the structural composition of TBM brush mainly includes:
Front shield anti slurry brush: located at the front end of the front shield, with a detachable design, used to prevent slurry from entering the interior of the front shield.
Upper and lower tail brushes: located on the shield wall at the rear end of the tail shield, corresponding to the front shield anti slurry brush, used to prevent mud and gravel from entering the interior of the equipment at the rear end of the tail shield.
These brushes are usually installed in the corresponding positions of TBM equipment through bolts or other fixing methods to ensure their effective operation during excavation.
