The invention provides a bridge facility. The bridge facility comprises an electric connection base fixedly disposed in a bridge wall body and an electric connection end connected with electrical maintenance equipment. Inserting grooves having open ends facing rightwards are correspondingly disposed in the electric connection base in an up-down way, and contacts connected with commercial power are fixedly disposed in the inserting grooves. A sliding pushing groove extended leftwards and rightwards is used to communicate the inserting groove, and is disposed between the two inserting grooves of the electric connection base. A sliding bench is movably disposed in the sliding pushing groove, and a through groove used to communicate the upper part and the lower part is disposed in the sliding bench. A rotating arm is movably disposed in the through groove by a first rotating rod, and the front end and the rear end of the first rotating rod are respectively and movably disposed in the front end wall and the rear end wall of the through groove, and the front end and the rear end of the first rotating rod are fixedly provided with screw-on springs fixedly connected with the sliding bench, and the screw-on springs are used to keep the vertical state of the rotating arm, and then the rotating arm can be inserted in the inserting groove, and in addition, the left end wall of the sliding pushing groove is fixedly provided with an electric button used to control the electrification of the contact.
