Abstract

PURPOSE: To remove snow by means of snow flow channels on a gentle grade area by providing the group of snow flow channels while communicating a number of circulating snow flow channels to one another by means of overflow passages from upstream to downstream of a gently sloping urban area, and making the group of snow flow channels deeper on the downstream side than on the upstream side. CONSTITUTION: In a relatively level urban area 2, a group of endlessly excavated snow flow channels 4 are provided, and the snow flow channels 4a-4c are connected together by overflow passages 5. Each show flow channel 4 allows circulation of water by a pump 8, and each snow flow channel 4 and each overflow passage 5 are formed to get deeper in steps from upstream to downstream. The water of a river 3 is guided upstream of the group of snow flow channels via a water conduit 6, and as snow dumped into each snow flow channel 4 in the urban area 2 is melted, overflow is made to flow down the upstream snow flow channels to the downstream snow flow channels and is finally discharged into the river via a drainage passage. Therefore, snow can be removed by means of the snow flow channels in the gently sloping urban area 2.
