Abstract

PURPOSE: To provide with a place where fishes flee of safety from a rapid current and live and to revive a river to a natural environment which was maintained before the river is repaired, by a method wherein a hollow portion and perforations are provided in a coupling block to form a fish nest.
CONSTITUTION: A base 1, which is flat, rhombic, and thick, and a projection portion 2, whose ridge is formed in a wide slope, are united into a monolithical unit, and perforations 3 and 4 are made in both sides of the base 1 and in the projection portion 2, respectively. A reinforcing rod insertion hole 5 is made in a center of the base 1, and connecting rings 6, 6 are projectedly formed at both sides thereof. A great many of connected blocks 7 so formed are continuously connected together in zigzag, and the reinforcing rod insertion holes 5 are coupled together to insert a reinforcing rod bar 8. Bank protection blocks so connected together are laid flexibly on a river bed. As a result, the perforations 3 are connected together to form a hollow portion which serves as a long and narrow tunnel-shaped fish nest and to enable each perforations 4 to form an independent fish nest.
