A ecological merit band structure of three -layer step for river engineering

The utility model discloses an ecological merit band structure of three -layer step for river engineering, including three -layer step ecological functions area, three -layer step ecological functions area comprises the aquatic plant layer of bottom, the shore water pavement layer at middle part and the levee crown road layer on upper portion, an upright wall of building by laying bricks or stones for the ecological geotechnique's bag through high 0.8 -1.2m between aquatic plant layer and the shore water pavement layer links up mutually, be 1 through ecological interlocking brick and side slope between shore water pavement layer and the levee crown road layer: 2 or 1: 3 the grassed slope connect mutually. The utility model discloses the advantage mainly embodies and adopts three -layer step ecological functions area in the river engineering, makes the river course after the renovation can satisfy the water drainage demand of river course surrounding area, can form again and go sightseeing to lie fallow the shore hosepipe, holds the difference through this kind of different water level elevation's great groove, has improved surface of water rate, does benefit to the contradictory problem of solving the river course surrounding area and holding the waterlogging and take over the land for use, has slowed down the whole side slope in river course, is favorable to the stability of river course side slope.
