Abstract
PURPOSE: To provide a retaining wall suitable for the growth and propagation of fishes without sacrificing the strength as a retaining wall by providing intercommunicated large hollow portions at the inside of a wall portion for slope.
CONSTITUTION: A slope protection work for a river or the like is first conducted, then foundation cobble stones 20 are placed on the riverbed or the like, and foundation concrete 19 is placed on the cobble stones 20. On the other hand, an inside wall portion 15 is formed on the front surface of the earth wall 14, and blocks 12 for fish nest are placed in parallel with the inside wall portion 15. The block 12 forms passages 18 by cooperation of each pair of adjacent ones of them and provide hollow portions A. Then, blocks 11 are piled on the front surface of the blocks 12 to form a wall portion 10 for slope. In this case, passages 17 communicated with the hollow portions A of the blocks 12 are provided by aligning the through-holes 16 formed in the wall 10 with the notched portions 13b of the blocks 12.
