Liftable track wheel shaping steel mould supporting system for large-section open cut tunnel

The invention belongs to the technical field of open-cut tunnel construction supporting, and solves the problems that a traditional shaping steel mold is difficult to assemble, low in mold removal speed and inconvenient to correct. The large-section open-cut tunnel liftable track wheel shaping steel formwork supporting system comprises an arch formwork, a plurality of arch frames arranged at intervals, an inner supporting structure, side wall formworks, tracks and track wheels, the arch formwork is fixed to the outer sides of the arch frames in an attached mode and matched with the outline of a tunnel, and the side wall formworks are arranged between the bottom end of the arch formwork and the bottom face of the tunnel. The inner support structure comprises a transverse support, a longitudinal support and a vertical support, the inner support structure is used for supporting the arch formwork and the side wall formwork, the track is laid on the bottom face of the tunnel in the length direction of the tunnel,
