The invention relates to a tank container with a rotary boardwalk structure. The tank container with the rotary boardwalk structure mainly comprises a tank body, a framework, valves and a boardwalk device. The boardwalk device is supported and installed at the top of the framework through boardwalks and comprises a full-walk structure composed of the two longitudinal boardwalks and the multiple transverse boardwalks. The transverse boardwalks comprises the fixed transverse boardwalks and the rotary transverse boardwalks, one ends of the rotary transverse boardwalks are connected with the fixed transverse boardwalks through hinges, and the other ends of the rotary transverse boardwalks are locked on the fixed transverse boardwalks through locking devices. The rotary transverse boardwalks are installed above the valves of the tank body, and when the rotary transverse boardwalks are opened, the valves on the tank body can be operated. By the adoption of the scheme, full-walk arrangement of the top of the tank container can be realized, the valves at the top of the tank container are favorably protected, and the tank container has the advantages of being low in manufacturing cost, convenient to operate, high in practicability and the like.
