Orbital volcanic ash accumulation prevention structure

摘要

A structure for reliably preventing volcanic ash from accumulating on a railroad track when the above-mentioned volcano erupts. A structure for preventing volcanic ash accumulation on a track that prevents volcanic ash from accumulating on a track of a railway 10 at the time of a volcanic eruption, at a height that covers the overhead line 11 on the track of the railway 10 A roof portion 100 mounted to extend a predetermined length along the track 12 of the railway 10 with a predetermined width sufficient to prevent volcanic ash from accumulating on the track; The roof portion 100 has a water supply portion 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 flow supply unit 200 is attached along the extending direction of the track 12 on the upstream side of the roof in the water flow direction. [Selection] Figure 4
