Road water accumulation prevention drainage structure for water conservancy investigation design

The utility model discloses a road water accumulation prevention drainage structure for water conservancy investigation design, which relates to the technical field of drainage structures and comprises a drainage channel, a cavity is arranged on the side wall of the drainage channel, a mouth-shaped foam board is arranged inside the cavity, and a leakage net is mounted below the foam board inside the cavity. A plurality of water inlet holes which are uniformly distributed and are communicated with the cavity are formed in the upper surface of the drainage channel; a filtering chamber is arranged below the drainage channel; according to the design, pedestrians can be warned and prevented from falling into a drainage channel, accumulated water is filtered through a filter screen type conveying belt, garbage in the accumulated water is left above the conveying belt, then falling water falls on fan blades, the fan blades drive a shaft rod to rotate forwards through gravity, and the shaft rod rotating forwards driv
