- 摘要:
- 以安全、可靠、经济、与道路景观相协调为设计原则，进行了四川省渠县黄花大道综合管廊的通风设计。介绍了通风方式、机械排风机房及排风亭的布置、自然进风亭的布置，并阐述了平时通风、巡检通风、事故通风及火灾后通风的监测与控制。设计特色如下：机械排风机房的检修口兼作管廊巡检人员的疏散口、机房设备的投放口；在出地面的自然进风亭侧壁上设置气体灭火系统的泄压口；采用防爆单速排风机，一机多用，节省成本；根据通风换气次数和控制舱室内氧气的体积分数来确定巡检人员进入舱室前应提前开启排风机的时间。
- Abstract:
- According to the design principle of keeping safe, reliable, economic and coordination with road landscape, we conducted the ventilation mode, the layout of the mechanical exhaust fan room and the exhaust pavilion and the layout of the natural air intake pavilion of Huanghua Avenue utility tunnel in Qu County, Sichuan Province. It also elaborated the monitor and controlling system of its normal ventilation, inspection ventilation, accident ventilation and ventilation after the fire. The design features were as follows: The overhaul port of the mechanical exhaust fan room was also used as the evacuation port for inspectors and the equipment delivery port of the fan room; The pressure relief port of the gas extinguishing system was set on the side wall of the natural air intake pavilion above the ground; An explosion-proof single speed exhaust fan with multiple functions was used for saving the costs; The ventilation frequency and controlling the volume fraction of oxygen in the cabin were used to determine the opening time of exhaust fan before the inspectors enter the cabin.
