[0002] In the field of water conservancy, when a river bends, the river bank at the bend is the most severely eroded by the river. When the river bends in urban areas or towns, once a natural disaster such as a sudden rainstorm occurs, the water volume of the river will increase dramatically, which can easily overflow the river bank and threaten the lives and property of residents living near the river.
[0003] The existing river embankment structure at the river bend is generally reinforced with a concrete protective layer to protect the concave bank embankment. However, since the existing protective structure is relatively simple, the protective structure is severely damaged when the water flows at a fast speed at the concave bank for a long time, thereby affecting the service life of the protective structure.
[0004] Therefore, the present application proposes a flood control embankment structure at a river bend to solve the above-mentioned problem. Utility Model Content

[0012] Compared with the related art, the flood control embankment structure at the river bend provided by the utility model has the following beneficial effects:
[0013] 1. The utility model provides a flood control embankment structure at the bend of the river. In this scheme, an impact protection body is arranged on the inner side of the concave bank embankment body, and a diversion buffer area is arranged on the inner wall of the concave bank embankment body.
