Description

Technical Field

[0001] The utility model relates to the technical field of tail parts of shield machines, in particular to a wire brush with high sealing effect. Background Art

[0002] The sealing effect of the shield tail brush is mainly determined by the shield tail brush structure and the sealing grease between the three shield tail brushes. In shield construction, when the shield tail brush is worn to a certain degree or the shield tail sealing grease is missing, it is easy to cause water leakage and sand leakage at the shield tail. In severe cases, the ground sinking and collapse accidents may even occur. Therefore, once it is found that the shield tail brush is damaged to a large extent, it is necessary to replace the shield tail brush in time. The original brush provides sealing by the friction between steel and grease. Due to the small friction, it is easy to be penetrated by water pressure and lose the sealing effect. The original brush is installed in blocks in the annular direction, and the blocks are disconnected, which has weak sealing points.

[0003] The wire brush is installed on the inner wall of the tail of the shield machine. If the sealing of the wire brush is not good, there will be a risk of leakage. Utility Model Content
