Retaining dam protection structure

The utility model discloses a retaining dam protection structure which comprises two installation bases fixedly installed on the top of a retaining dam body, a shaft rod is arranged between the two installation bases, two side plates are welded to the surface of the shaft rod, and a cleaning buffering assembly is arranged between the two side plates and corresponds to the slope of the retaining dam body. The cleaning buffer assembly comprises mounting grooves symmetrically formed in the close sides of the two side plates. When the retaining dam protection structure is used, the state that the bottom ends of the side plates are erected on the surface of the bearing seat is kept, at the moment, the buffer plates are obliquely erected in the water body, the surface of the retaining dam body can be subjected to impact protection through the buffer plates, and under the undulation effect of the water body, the buffer plates are stressed to drive the limiting sliding blocks to move along the surfaces of the limitin
