Orbital volcanic ash accumulation prevention structure

摘要

PROBLEM TO BE SOLVED: To provide a structure for reliably preventing volcanic ash from accumulating on railroad tracks when the above-mentioned volcano erupts. A volcanic ash deposition preventing structure for preventing volcanic ash from being deposited on a track of a railroad 10 at the time of a volcanic eruption, at a height on the track of the railroad 10 and covering an overhead line 11. A roof portion 100 attached so as to extend for a predetermined length along the track 12 of the railway 10 while having a predetermined width sufficient to prevent the deposition of volcanic ash on the track. , Having a water sink supply unit 200 for flowing water over the entire roof portion, and the roof portion 100 is inclined from the upstream side to the downstream side in the water flow direction from one end in the width direction to the other end in the width direction. The water sink supply unit 200 is attached along the extending direction of the track 12 which is upstream of the roof in the water flow direction. [Selection diagram] Figure 4
