Orthotropic combined bridge deck slab with replaceable damage elements and construction method thereof

The invention belongs to the technical field of bridge construction, and particularly relates to an orthotropic combined bridge deck slab with replaceable damage elements and a construction method thereof. The orthotropic combined bridge deck slab is suitable for large-span bridges which are large in traffic volume and need rapid recovery of use functions. The orthotropic combined bridge deck slab comprises a steel structure component and a concrete slab poured at the top of the steel structure component; the steel structure component comprises a reinforcing mesh, a top plate, a plurality of cap-shaped longitudinal ribs, a plurality of transverse partition plates and replaceable damage elements. The top plate is laid at the bottom of the reinforcing mesh, the bottom of the top plate is connected with a plurality of cap-shaped longitudinal ribs arranged at intervals, and the top flange is detachably connected with the top plate through a high-strength bolt connecting pair A; the transverse partition plates are
