Method for arranging double contact net stand columns on inner side of U-shaped beam line

The invention discloses a method for arranging double overhead line system stand columns on the inner side of a U-shaped beam line. The method comprises the steps that two U beams are arranged side by side, the two overhead line system stand columns are arranged at the joint of the two U beams, and the two overhead line system stand columns independently supply power to vehicles in the two U beams respectively. The catenary stand columns are arranged on the inner sides of the two U-shaped beams respectively and used for independently supplying power to vehicles going up and down, so that transportation of rail transit on the other side is not affected when accidents, maintenance and overhaul happen to one side, operators can be prevented from being injured by electric shock, parallel rails can still run normally when crowds are evacuated in a shutdown mode, and the safety of the operators is guaranteed. Therefore, danger caused by the fact that evacuated crowds are involved by airflow is avoided, and meanwhil
