Air-chambers 21, 23 and 25 capable of expansion connecting with exhaust pipes 27, 29 and 31 are provided to the lower part of each of the lock rooms. In addition, opening and closing valves 33, 35 and 37 are respectively provided to the exhaust pipes 27, 29 and 31. Then, after a ship K in the lower stage waterway 1 is led into the lock room 5 by opening a gate 13 of the lower stage lock room 5, the opening and closing valve 33 is opened to send air from the exhaust pipe 27, the air chamber 21 is expanded to raise a horizontal plane, and simultaneously the horizontal surface of lock room 7 is lowered to move the ship K.
