Pressure balance type floating body and installation method thereof

A pressure balance type floating body, comprising water cabins, gas cabins, underwater even pressure control systems for controlling the gas pressure in the body of the floating body, gas cabin inflation valves, water cabin water supply systems and water cabin ventilating systems, wherein the water cabins and the gas cabins are not communicated;

• the buoyant center of the floating body and the gravity center of the floating body are located on the same vertical line, and the position of the buoyant center of the floating body is higher than the position of the gravity center of the floating body;
• the water cabins and the gas cabins are arranged at the left and right sides of the floating body, and the buoyant force provided by the water cabins and the gas cabins at the left side of the floating body is equal to the buoyant force provided by the water cabins and the gas cabins at the right side of the floating body;
• the water cabins and the gas cabins are arranged at the front and back sides of the floating body, the buoyant force provided by the water cabins and the gas cabins at the front side of the floating body is larger than the buoyant force provided by the water cabins and the gas cabins at the back side of the floating body, or the buoyant force provided by the water cabins and the gas cabins at the back side of the floating body is larger than the buoyant force provided by the water cabins and the gas cabins at the front side of the floating body;
• the water cabin water supply system and the water cabin ventilating system are arranged on each water cabin;
• one gas cabin inflation valve is arranged on each gas cabin;
• the underwater even pressure control systems are connected with the gas cabins.
