2. The bridge deck is hinged: directly implanting a steel bar or a steel structure at the cantilever end of the existing bridge deck slab, correspondingly welding the steel bar or the steel structure with the reserved steel bar or the steel structure of the newly-built bridge deck slab, and connecting the steel bar or the steel structure to form a hinge; the bridge manufactured by the method is smooth in driving and good in comfort, but the stress mode of the existing bridge is changed, so that reinforcement treatment is needed, the reconstruction workload is large, the structure is complex, and meanwhile, the hinged part is easy to damage due to long-term rolling of a motor vehicle, and the maintenance workload is large.
3. Carrying out rigid connection on the bridge deck: firstly, steel bars or steel structures are implanted into an existing bridge, the existing bridge is rigidly connected with newly-built bridge steel bars or steel structures, and then the bridge is paved together, so that the method is smooth in driving and good in comfort; however, because the stress mode of the existing bridge changes, reinforcement treatment is needed, and meanwhile, because the rigid connection bridge deck structure is complex, the stress of the bridge structure is complex, new bridge diseases are easily formed at the connection part as follows: the age difference of the concrete is large, so that the problems of cracking, steel structure fatigue and the like are caused, the modification workload is large, and the use cost is high.
