The invention belongs to the technical field of bridges, and particularly relates to a municipal emergency overpass. The municipal emergency overpass comprises two bases,
pier bodies made of steel trusses are arranged at the tops of the bases, platforms are fixedly connected to the tops of the
pier bodies, bridge decks are hinged at one sides of the platforms, oil cylinders are obliquely arrangedbelow the bridge decks, one ends of the oil cylinders are hinged to the bottoms of the bridge decks, the other ends of the oil cylinders are hinged to the upper parts of the
pier bodies, the oil cylinders are connected with high-pressure oil pumps through valves and pipelines, when the bridge decks work, the bridge decks are folded after being contracted through the oil cylinders, so that the occupied area is reduced, one side, far away from the corresponding pier body, of one
bridge deck on one side is provided with a group of clamping openings, the positions, corresponding to the clamping openings, of the side surface of the
bridge deck on the other side are provided with a group of T-shaped clamping columns, and the two bridge decks are mutually locked through cooperation between the clamping columns and the clamping openings. According to the municipal emergency overpass, the oil cylinders push the bridge decks to slow rotate, then the clamping columns are clamped into the clampingopenings to enable the two bridge decks to be tightly connected, namely the bridge decks can be rapidly installed in place, the use of large-scale hoisting equipment is avoided, and the installationefficiency of the overpass is improved.
