Preferably, a transition slope is arranged between the cast-in-place concrete module positioned at the lowest part and the retaining wall, and the cast-in-place concrete module, the transition slope and the retaining wall are built into a whole. The transition slope is used for connecting the lowest cast-in-place concrete module with the retaining wall, and plays a role in supporting the foundation.

Preferably, a protective wall is arranged on the retaining wall. The protective wall plays a role in protection and blocking, and people are prevented from falling into a river channel after accidentally rolling down from a slope.

Preferably, the top of the backfill slope is provided with a capping.

Preferably, the ecological slope protection structure of the concrete river further comprises a bearing layer and a block stone leveling layer, wherein the block stone leveling layer is arranged on the bearing layer, and the backfill slope and the retaining wall are arranged on the block stone leveling layer. The bearing layer plays a bearing role, can avoid sedimentation of the utility model, and can be built by rubble.

Preferably, the thickness of the coarse sand cushion layer is 100-150 mm.

Preferably, the thickness of the crushed stone cushion layer is 150-200 mm.

Therefore, the utility model has the following beneficial effects:

(1) The structure is simple, the air permeability is good, the cost is low, the construction is simple and convenient, and the later dismantling is convenient;

(2) Not only can effectively protect the two sides of the river channel, but also can restore the destroyed natural ecological environment.
