Cable routing is required to be not only accurate, but also aesthetically pleasing and space efficient. In the field construction, a plurality of bridges arranged in parallel on the same plane need to be introduced into an equipment room vertical to the bridges, and at the moment, all bridges except the equipment room need to be turned over and bent to be introduced into the equipment room. If N bridges are adopted, N-1 times of bending is needed. The method can be completed under the condition that the space allows, but the aesthetics is not good, and when a plurality of bridges are usually vertically arranged, the space is narrow, and the condition that the plurality of bridges are turned over and bent at the same time may not be met. How to fully utilize the limited space and ensure that cables in bridges of different systems are safely crossed is a technical problem.
