POROUS BLOCK FOR ECOLOGY RESTORATION OF WATERWAYS

摘要

PURPOSE: A porous block for ecology restoration of a river is provided to prevent the water quality from being not purified due to toxicity generated in cement structure and the cement structure in which aquatic organism is unable to live in case a riverbed protection block is formed using concrete. CONSTITUTION: A porous block for ecology restoration of a river comprises a frame part(1), a passage part(10), and a projection(20). The frame part is molded along a hoop shape. A through-hole(15) is equipped in the inner side of the frame part. The passage part forms an ecological passage(12) in the frame part to connect the through-hole and the outer side of the frame part. In the projection, a combining projection(22) is protruded on the one side among the upper side and the lower side of the frame part including the passage part.
