Multi-layer anti-seepage structure suitable for urban river channel

The utility model belongs to the technical field of urban river channels, and particularly relates to a multi-layer anti-seepage structure suitable for urban river channels, which comprises a main body, the main body comprises a slope protection brick layer, a compression-resistant anti-impact layer, a first concrete layer, an inner core layer, a second concrete layer and a base layer which are sequentially arranged from outside to inside, and reinforcing steel bar layers are arranged on two sides of the inner core layer. A surface turf layer is arranged at the top of the main body, and a fixing rod is fixedly mounted on one side of the main body. The structure is composed of the slope protection brick layer, the compression-resistant and impact-resistant layer, the first concrete layer, the inner core layer, the second concrete layer and the base layer which are sequentially arranged, the multi-layer composite anti-seepage structure is adopted, so that the anti-impact capacity of a riverbed is high, and the
