OPEN WATERWAY PIPE

摘要

PURPOSE: An eco-friendly protrusion type open channel pipe is provided to generate sound since water is periodically hit against various protrusions during the flow of water therein. CONSTITUTION: An eco-friendly protrusion type open channel pipe has the shape of an open-top water channel. A bottom plate(30) is formed in the longitudinal direction of an open channel pipe. Both side plates(40) are integrated with both sides of the bottom plate. The multiple protrusions of the various shapes are formed on the bottom plate at regular intervals.
