METHOD FOR GENERATING RAINBOW OVER BRIDGE AND BRIDGE HAVING RAINBOW GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve a fine sight of a bridge by installing spray nozzles in the side face of one side or both sides of bridge girders and spraying water from the spray nozzles diagonally or right above. ;SOLUTION: Spray nozzles 7a-7h are installed so as to project upward at the side of both parapets of bridge girders installed on a bridge pier 4. Pipes 8a, 8b are connected to these spray nozzles 7 and a water supply pump is installed at the pipes 8a, 8b through valves. A water pipe 12 supplying water from a water supply tank 11 installed near a water source is connected to the pump through valves. Accordingly, a fog can be generated around the spray nozzles 7a-7h by supplying water to the spray nozzles and spraying water out of the spray nozzles 7a-7b in the upward diagonal direction or the right above direction. In this way, the fine sight of the bridge can be enhanced.;COPYRIGHT: (C)1999,JPO
