1、 Project overview:
This project is an air defense basement project in Jiangxi Province, the main basement building
The area is 16339.51m2, and the civil air defense building area is 10627m2
Effective area 12400m2, masking area 9330m2, masking number
9330 people
2、 Ventilation and smoke exhaust system:
1. Wartime ventilation system design:
The ventilation design of the second-class personnel shelter includes clean, poison filtering and isolation
Three ventilation modes;
Chemical protection grade: biochemical grade C for second-class personnel shelter works;
The project is equipped with a fixed power station in wartime, with two installed capacity in peacetime
N=250kw diesel generator set operates at the same time, one for use and one for standby in wartime.
2. Ventilation design at ordinary times and smoke control design in case of fire:
The garage in the civil air defense basement of the project is divided into four fire compartments
1. 2, 3 and 4 are divided into two smoke control zones
At least 500mm above the floor
3. Pressurized air supply design of staircase and antechamber:
All smoke proof staircases and antechambers without natural ventilation in the basement of the project
Positive pressure air supply system is set in the shared front room, and corresponding positive pressure air supply is set in case of fire
Start the machine to ensure the positive pressure of the smoke proof staircase is 40-50Pa, and the positive pressure of the front room
25-30Pa...
