An apparatus for draining infiltration water from the road surface of the bridge is provided to improve safety by draining the infiltration water on the bridge and preventing the infiltration water from being contacted with the bridge beam. An apparatus for draining infiltration water from the road surface of the bridge comprises a road surface infiltration water draining device(16) having a cup(14) providing a space(12) between a lower end(10a) of a draining pipe(10) and a concrete layer(2) at the lower end of the draining part; a road surface infiltration water draining guide pipe(18) fixed at the beam to allow the lower end of the draining device to be fitted in an inlet(18a) and place an outlet(18b) in a lower position than a lower surface(7a) of a bridge beam(7); an upper fixing device(20) fixing the inlet of the draining guide pipe at the lower side of the concrete layer; and a lower fixing device(22) fixing a lower part(18c) of the draining guide pipe to the beam. The road surface infiltration water draining guide pipe is a metal spiral corrugated pipe(18'). |
