摘要

PURPOSE: A water tub type fishway debris barrier is provided to prevent ecosystem from being destroyed by the installation of multiple water tub type fishway blocks. CONSTITUTION: A water tub type fishway debris barrier(A) comprises an overflow sidewall(1) and water tub type fishway blocks(3). The overflow sidewall is formed on the downstream side of the upper end of the debris barrier. A waterway(2) is formed on one side of the overflow sidewall. Sides of the multiple water tub type fishway blocks that have different heights contact each other on the downstream side of the debris barrier. The tub type fishway block comprises a bottom part and a sidewall. The sidewall is formed vertically to the bottom part of a square shape. A waterway groove is formed on the upper end of one side of the sidewall, and a waterway hole is formed on the other side of the sidewall.
