Supporting device for shield tunnel

The utility model belongs to the technical field of shield tunnel construction, and particularly relates to a supporting device for a shield tunnel. The supporting protection piece is located in the shield segment and arranged in the axial direction; the multiple sets of deviation rectifying mechanisms are arranged between the shield segment and the supporting protection piece in the axial direction; the deviation rectifying mechanism comprises a driving assembly, a deviation rectifying assembly and a deviation rectifying assembly. The driving assembly is installed on the outer side of the supporting protection piece. The supporting assembly is located on the driving assembly; the stress piece is located on the supporting assembly; the driving assembly drives the stress pieces in the same group to move to the same circumference, so that the outer walls of the stress pieces press the inner walls of the shield segments, and the supporting or deviation rectifying effect is achieved. 本实用新型属于盾构隧道施工技术领域，具体涉及一种用于盾构隧
