The utility model discloses an assembled steel pipe sheet structure for a shield tunnel communication channel, which aims to effectively improve the impermeability of the assembled steel pipe sheet structure. For this reason, the assembled steel tube sheet structure for shield tunnel communication passage provided by the present application includes multiple segment segments spliced in sequence along the longitudinal direction of the tunnel communication passage, and the first bolts are passed between the two segmented segment units. The components are locked, and the two spliced segment units are provided with nested annular bosses and annular grooves at the splicing seam, and the splicing seam is sequentially provided with a first rubber stopper from the inside to the outside. A water belt, a first water-swellable material layer and a second rubber waterstop. |
