 Similarly, for example, the connecting steel plate of a certain section of the steel joint within 2.2 meters in length, the outer ring of the steel joint has a piece of steel plate, which is welded through the joint; in the longitudinal direction of the tunnel, they are welded with the steel cap of the adjacent pipe joint and the steel structure of the final joint. There is only one steel plate in the inner ring of the steel joint, which is butted directly with the adjacent steel plate; in the longitudinal direction of the tunnel, it is welded with the cap of the adjacent pipe joint and the steel structure of the final joint. It is estimated that the weld length is about 12 meters in the range of 2.2 meters (also without considering the welding of the partition). Compared with before the adjustment of the connecting steel plate, the weld length is reduced by more than 50%, and the weld length of the whole project is reduced to 2000 meters. In order to reduce the workload of handling and installing the steel joint connection steel plate, part of the connecting steel plate assembly is suspended to the final joint structure in the factory. The ear plate is welded on the inclined surface of the final joint steel structure, and matching ear plate assemblies are welded on the steel plate assemblies, and the ear plate and ear plate assemblies are connected by pins. The steel joint inner ring connecting steel plate and outer ring connecting steel plate are treated the same, the difference is only that the welding position of the lifting lug is different. Through this method, the top wall and side wall parts of the connecting steel plate components are treated, and the connecting steel plate hanging on the final joint accounts for about 25% of the total connecting steel plate, which greatly reduces the handling and installation of the corresponding connecting steel plate on site.
