Zusammenfassung: | The invention belongs to the technical field of engineering operation, particularly relates to large-section I-shaped steel beam multi-point walking pushing equipment and a pushing process, and aims to solve the problems that in the prior art, when a cantilever is too long, the hogging moment and stress of the root of a bridge cantilever are gradually increased, whether a bridge pushing path deviates or not needs to be monitored all the time, and the pushing degree is low. According to the technical scheme, the device comprises a steel beam, a walking type pushing device, two bridge piers and sliding structures, the top of the steel beam is provided with multiple sets of stretching structures used for stretching the two ends of the steel beam, the walking type pushing device is arranged on the surface of a foundation and located at the bottom of the steel beam, and the tops of the bridge piers are provided with the sliding structures. By arranging the multiple sets of stretching structures at the top of the s |
