The technical scheme of the utility model is that: a cantilever ecological hydraulic retaining wall structure comprises a cantilever structure formed by a vertical wall and a bottom plate, wherein the inner side of the cantilever structure is earthwork, the outer side of the cantilever structure is a water body, and the outer side of the cantilever structure is provided with an inclined strut; the space enclosed by the inclined strut, the vertical wall and the bottom plate forms a cavity which is communicated with the water body.

Based on the technical characteristics, the wall body of the vertical wall is provided with a drain hole penetrating through the wall body, and a gravel belt is arranged in the earthwork at the rear part of the drain hole. The drain hole is arranged near the normal water level elevation of the water body.

Based on the technical characteristics, the planes among the inclined struts are arranged into mutually parallel strips.

Based on the technical characteristics, the plane between every two inclined struts is arranged in a zigzag shape.

Based on the technical characteristics, supports intersected with the inclined struts are arranged among the inclined struts, and grids are formed between the supports and the inclined struts.

The utility model discloses improve traditional cantilever retaining wall, through increase the concrete bracing in the cantilever structure outside, when making it stand the wall and can bear horizontal soil pressure, stand wall cross sectional dimension, arrangement of reinforcement rate economical and reasonable to can satisfy the fender soil requirement of hydraulic structure under the prerequisite that simple structure, engineering cost hang down. Simultaneously, this ecological water conservancy project retaining wall structure of cantilever and water intercommunication can provide the habitat for the aquatic thing, compromise ecological effect simultaneously.
