They can provide necessary conditions for organizational command, personnel shelter and medical rescue, so that emergency rescue work can be carried out in an orderly manner and the losses caused by disasters can be reduced to a minimum, thereby effectively protecting the safety of people's lives and property. Protective and sealed plugging plates can be used to block openings that are used in peacetime but not in wartime. Its characteristic is that the plugging plates can be installed in peacetime, but they must be placed in a designated location nearby. In wartime, the plugging plates will be quickly installed according to the pre-set conversion time limit to meet the requirements of protection and sealing.
