Fish Path SPIRAL
The method of stacking fishway blocks in an oval shape allows for a significant reduction in the site area.
■The method of stacking fishway blocks in an oval shape significantly reduces the site area. ■The product shapes used for the curved and straight sections are standardized, which enhances workability. ■By creating a track shape with straight sections between the semicircular parts, the flow conditions in the pool are adjusted to facilitate fish ascending. ■The slope of the fishway has the semicircular return section at level and the ascending straight section at a gentle slope of 1/10, improving the ascent efficiency compared to a circular shape. ■The partition wall adopts an ice harbor method that accommodates small fish species. ■By rounding the shape of the overflow section of the partition wall, it creates a submerged flow that is easier for fish to ascend. ■Overflowing at the fishway outlet section allows for adjustment of the fishway flow rate. ■Light windows are installed to ensure adequate illumination.
