Civil air defense projects are important facilities for preventing sudden enemy attacks, effectively sheltering personnel and materials, and preserving war potential; they are engineering guarantees for persisting in urban battles and supporting anti-aggression wars for a long time until victory. Civil air defense projects generally need to be equipped with closed doors, flood prevention and drainage equipment, and ventilation equipment.
