In summary, the present application includes at least one of the following beneficial technical effects:

1. Through setting up first guiding gutter, second guiding gutter and conflux groove to make the rainwater fall to the ladder surface from the second guiding gutter that the slope set up, first guiding gutter finally assemble to conflux inslot, make the rainwater can flow out the ladder with more regular orbit, reduce the rainwater on stair surface and collect, reduce the circumstances such as the splash pollution that probably leads to when pedestrian walks, and the rainwater finally flows from conflux groove, can not directly splash to the pedestrian's way of below from the high altitude, further reduce the pollution to the pedestrian;

2. Through setting up the detachable limiting plate of pull formula busbar and bolt to make the busbar maintenance that can be more convenient.
