Aiming to large slope and large section in the weakness removal of right bank spillway tunnel of Xiluodu Hydropower Station, the spider-type aerial working platform was used in weakness removal and post treatment of spillway tunnel by referring to the experience of climbing and maintenance operation in civil engineering. This platform gives full play to the mechanized con-struction advantages of less construction space and higher efficiency, which can save the cost and ensure the construction quality, safety and progress. The special transformation of spider-type aerial working platform and the swing-type crossing aerator by self-elevating were introduced. So the platform is adequate for the weakness removal and post maintenance in spillway tunnel with complex design shape, and can successfully implement the deep mechanized construction.
