The invention discloses a municipal administration path drainage structure with an emergent drainage function. The municipal administration path drainage structure can effectively solve the problems that due to the fact that a drainage pipeline is blocked, the amount of surface gathered water is excessively large, and normal use of the road surface is seriously affected. The municipal administration path drainage structure comprises a sink arranged on the road surface, a drainage pipeline embedded underground, a vertical flow guiding pipeline, a water drainage connecting pipeline and an emergent drainage device, wherein a rainwater perforated strainer is arranged at the upper end of the sink, the vertical flow guiding pipeline is located below the sink, the upper end of the vertical flow guiding pipeline is communicated with the bottom face of the sink, a flow guiding pipeline drainage outlet is formed in the lower portion of the outer side face of the vertical flow guiding pipeline, and a filter net device is located at the portion, above the flow guiding pipeline drainage outlet, inside the vertical flow guiding pipeline, the upper end of the water drainage connecting pipeline is connected with the flow guiding pipeline drainage outlet, and the lower end of the water drainage connecting pipeline is communicated with the drainage pipeline.
