Preferably, first barricade is including being located the bottom plate and being located wall body on the bottom plate, the wall body is made by the grouted rubble, the top of wall body has still been pour the concrete and has formed the protective layer.

Preferably, the cross section of the flower bed body of the flower bed is semicircular, the flower beds on each step are adjacently arranged, and the plurality of flower beds are arranged in a wave shape.

Preferably, a pebble green belt is further arranged above the backfilled gravel soil and is positioned between the water permeable bricks and the first retaining wall.

Preferably, the second retaining wall is formed of grouted block stones, and a rear side of the second retaining wall is obliquely arranged.

Preferably, the distance between the wall top of the second retaining wall and the designed river bottom is 0.5-1 m.

Preferably, the front side of the dike foot of the second retaining wall is paved with egg floating rockfill.

As above, the utility model relates to an urban mountain area river course shore protection structure has following beneficial effect: the utility model discloses the ecology is better, adopts second grade barricade structure, and the staggered arrangement of height has in tandem, and first barricade can play the flood control effect, is equipped with the flower bed on the first barricade, provides ecological space for the plant, has laid the brick that permeates water between second barricade and the first barricade and has formed hydrophilic pavement, can supply people to walk. The utility model discloses both satisfy basic flood control safety and compromise the functional demand that the ecological hydrophilic of river course exchanged.
