And (4) equipment composition. The bottom film is mainly used for foundation sealing to realize corrosion prevention and seepage prevention which cannot be achieved by the traditional infrastructure; the isolating membrane is used for isolating the stored gas and the outer membrane pressure regulating gas; the outer film forms a pressure regulating chamber, so that the isolating film is suitable for outputting gas at constant pressure and has a protective effect on the isolating film. The principle is that the bottom film and the outer film jointly form a closed air storage space, and when the amount of stored air increases, the control equipment releases pressure-regulating air to generate a certain volume. When the gas stored in the isolating membrane is reduced, the control equipment injects pressure-regulating air to balance the pressure in the cabinet and stabilize the rigidity of the outer membrane. In order to prevent the gas from mixing, the stored gas and the pressure-regulating air are separated by using an isolating membrane.
