The invention discloses an installation method for a cross-channel arched steel structure, which does not need to arrange a temporary support structure in a channel, and reduces the measure cost of structure installation. Meanwhile, the high-altitude installation workload is reduced, and the structure installation risk is reduced while the installation precision is guaranteed; and meanwhile, the problem of shaking of the lifting structure in each construction stage is solved. According to the structural damping box and the damping lifting appliance provided by the invention, adverse effects on an upper force exerting structure caused by shaking of a lifting structure due to factors such as sea waves and sea wind in each construction stage can be obviously reduced.
