STRUCTURE OF FISH WAY BLOCKS AND THE METHOD FOR CONSTRUCTING THE FISH WAY

摘要

PURPOSE: A fish-way block assembling structure and a construction method thereof are provided to facilitate an ascending of fishes within about 700 mm depth of water and let fishes to move to all directions by installing an undermining. CONSTITUTION: A fish-way block assembling structure(100) is composed of a plurality of first overflow blocks(110) and second overflow blocks(210). The plurality of first and second overflow blocks are adjoined to each other one by one toward a horizontal direction, thereby being arranged in a several rows. The height of the first overflow blocks is higher than the second overflow blocks so that fishes move through the water stream above the plurality of second overflow blocks in the upstream. The fishes move to left and right directions through the water stream above a first connecting bar(132) of the first overflow blocks and a second connecting bar(232) of the second overflow blocks.
