Abstract: PURPOSE:To purify and enhance the environment of a river by cutting out the center part of a box-like block body so as to form a cruciform sectional shape part, and by stacking such box-like blocks one upon another in multi- stages so as to provide water channels among the box-like blocks. CONSTITUTION:Box-like block bodies 4 center-part of each formed with a cruciform block part 5, are stacked one upon another in multi-stages so as to form water channels 6 which are communicated together through the cruciform parts 5. Vortices are created in water having flown into the water channels 6 from a river, and air is trapped in the water so as to produce fine air-bubbles in the water which can purify the river. Then, left and right blades 5b of the block part 5 shield off light so as to make a space thereunder dark, and accordingly, the water temperature or the like is set in a uniform condition, and further, since the flow rate of water is lowered by the water channels 6, a place where fishes can easily live can be provided. Thereby it is possible to purify a river and to provide a fish nest.
