Tunnel ground crack water stop fixing structure

The utility model relates to a tunnel ground crack water stop fixing structure which comprises a parallel-shaped water stop, the bottom of the parallel-shaped water stop is fixed to a tunnel primary support through bolts, annular fixing steel bars are arranged on the upper surface of the bottom of the parallel-shaped water stop, and oblique supporting ribs are arranged between the annular fixing steel bars and tunnel secondary lining longitudinal distribution ribs. One end of each oblique supporting rib is fixed to the tunnel secondary lining longitudinal distribution rib in a welded mode, andthe other end of each oblique supporting rib provides an acting point for the annular fixing steel bars. According to the utility model, the parallel waterstop is positioned along the longitudinal direction of the tunnel, the rigidity of the parallel waterstop is improved, the mounting precision of the parallel waterstop in the deformation joint is improved, and the fixing difficulty of the parallel waterstop is reduced.
