Zusammenfassung:The utility model relates to a vertical slot fishway provided with 180-degree curve sections. The vertical slot fishway comprises a straight section formed by connecting a plurality of pools with inclined bottoms; the 180-degree curve sections which enable the fishway to curve are inserted in the pools; each 180-degree curve section comprises a semicircular outer wall and an inner wall for separating pools at upstream and downstream; a turning point of each inner wall is provided with a guide plate which is parallel to upstream partitions and is shorter than the upstream partitions; the inner side of the outer wall is uniformly provided with two curve section guide plates along the circumferential direction. The vertical slot fishway provided with the 180-degree curve sections are arranged, a site condition is fully utilized and the space of the fishway is saved. As guide plates and curve section guide plates are adopted, flow structures in the curve sections are obviously improved, and the vertical slot fishway curves smoothly. The 180-degree curve sections provide a wide rest space and a good flow environment for fish, have the function of a rest pool, and are favorable for fish to gather strength in the upstream process and continue the upstream travel.
