Floating type mooring facility based on wharf water level change

The utility model relates to a floating type ship tying facility based on wharf water level change. The floating type ship tying facility solves the problem that a floating type ship tying column and a slope surface of a gravity type wharf cannot be directly applied. The device comprises a gravity type wharf, a main body of the gravity type wharf is a plain concrete wall body, a bottom reinforced concrete bottom plate of the plain concrete wall body and a top reinforced concrete coping of the plain concrete wall body, the front side wall of the plain concrete wall body is a slope surface, a vertical slide way is formed in the front side wall of the plain concrete wall body, a buoy is arranged in the slide way, and bollards are fixed to the upper portion of the buoy forwards. The front side face of the slide way is open, the bottom of the slide way extends to the upper surface of the reinforced concrete bottom plate, the top of the slide way upwards penetrates through the reinforced concrete coping to be open,
