BRIGE OF HEIGHT VARIABLE

摘要

The present invention provides a bridge with a variable height comprising a road surface part having a road surface at the upper part; a bridge support part of which one side is fixed to the ground and which is mounted on the lower part of the road surface part to support the road surface part; and a floating part which is disposed between the bridge support part and the road surface part and varies height of the road surface part while moving vertically by buoyancy when water flows inside. The bridge with a variable height according to an embodiment of the present invention provides an effect that the road surface part moves up by buoyancy according to a water level to prevent a bridge fromb being flooded althrough the water level of a stream rises.
