Discussion on several common problems in civil air defence ventilation design

Aiming at the inappropriate choice of design code in civil air defence ventilation, presents the application scope and differences between Code for design of civil air defence works and Code for design of civil air defence basement. According to the smoke control and extraction design, states respective application scope and differences among the Code for fire protection design of civil air defence works, Code of design on building fire protection and prevention, and Code for fire protection design of garage, motor-repair-shop and parking-area. Current codes do not specify the application scope of water-cooled power station. Suggests increasing the corresponding provisions. Illustrates the practice of the setting position, diameter, and material for the pressurized pipe, and gives the solution for the omission holes, pipeline fights and other engineering common problems.
