Abstract

PURPOSE: To prevent the spreading of the impact sound of water by covering a water surface where the impact sound is generated due to the dropping of overflow water from a gate with a sound-proof plate moving over a given height on the water surface in the downstream side of the gate in response to the opening or closing operation of the gate.
CONSTITUTION: An overflow type gate 1 is extended from upstream side 2 to down-stream side 3 and pivotally attached to a bearing 5 through a shaft 6. Then, a sound absorber 8 built in a sound proof plate 7 is provided between bridge girders 4 and a pin 10 is pivotally attached to an arm 9 projectionally provided to the gate 1. And, the free end of the sound proof plate 7 is supported in a freely movable manner by a roller 12 provided at the top of a strut 11 erecting on the downstream side 3. Thus, even when the dropping position on which overflow water collides against water surface on downstream side 3 is moved by the opening degree of the gate 1, the sound proof plate 7 can be moved in response to the opening degree of the gate 1 and therefore, the spreading of the drop and impact sound of overflow water can be shielded and damped.
