凤凰山隧道通风方案设计与实施

DESIGN AND IMPLEMENTATION OF VENTILATION SCHEME FOR FENGHUANGSHAN TUNNEL

隧道通风方式分为压入式、抽出式、混合式、巷道式、竖井式等几种方式,每种方式都有其使用条件和优缺点,通风方式的需根据隧道长度、断面大小、施工方法、设备条件综合设计通风方案,压入式通风可以使用柔性风管,风管重量轻,便于运输、安装、拆除,费用较低,有利于无轨运输方式,即自卸汽车运输。

Tunnel ventilation can be divided into press in type, extraction type, mixed type, roadway type,shaft type and other modes. Each mode has its use conditions, advantages and disadvantages. The ventilation scheme needs to be comprehensively designed according to the tunnel length, section size, construction method and equipment conditions. The press in type ventilation can use flexible air duct, which has small volume and light weight, and is convenient for transportation, installation The demolition cost is low, which is conducive to trackless transportation.
