FLOATING PIER STRUCTURE

PROBLEM TO BE SOLVED: To easily apply maintenance and management by installing an air reservoir tank or a bag below the free end of a tip bridge section, and pushing up the tip bridge on the water to prevent the sticking of shells and laver when it is not used. SOLUTION: When a tank is full of air, the discharge port side of a valve A controlling the force feed or discharge of air is opened, a valve B limiting the suction or drainage of water is opened, then water enters through a water suction pipe. Air is discharged from a discharge pipe, the air in the tank is substituted with water, the opening and closing of the valves are properly controlled, and the free end of a tip bridge section 4 is moved downward in the water. When water is filled in the tank, the valve B is opened, the air feed port side of the valve A is opened, and air is fed into the tank to discharge the water in the tank. The free end of the tip bridge section 4 is pushed above water, the valve A is closed, the air in the tank is kept stored, and the free end of the tip bridge section 4 is kept pushed up above water. The maximum inclination angles of a main bridge section 2 and the tip bridge section 4 are set to 15 deg. respectively.
