It is important that the lateral areas of each plate substantially encompass the lateral expanded areas of the respective skirt end. A plurality of controllable valves are provided for selectively opening and closing the passage of fluid. One of these valves is located in the bottom plate for selectively allowing the passage of water into or out of the container and another valve is located through the container and another for selectively introducing pressurized air into the container. A relief valve is also located through the container for relieving air from the container when the inside and outside differential pressure has exceeded a predetermined level. Author
