在小断面长距离隧洞施工中,合理的通风系统是实现隧洞快速施工的重要保证,理想的通风效果也决定着施工安全及施工人员身心健康。因此,在隧洞施工中,如何选择实用、合理的通风系统显得尤为重要。本文结合引汉济渭工程秦岭隧洞(越岭段)0-1号勘探试验洞工程现场实际,针对通风系统进行介绍。一、前言在隧道施工中,为了稀释和排出因爆破、机械运行等产生的粉尘和有害气体,保持良好的空气条件,避免职业病、中毒死亡等事故的出现,加快施工进度,通风系统的
In small-section long-distance tunnel construction, a reasonable ventilation system is an important guarantee for the rapid construction of tunnels. The ideal ventilation effect also determines the construction safety and the physical and mental health of construction workers. Therefore, in the tunnel construction, how to choose a practical and reasonable ventilation system is particularly important. In this paper, based on the actual situation of 0-1 exploration test tunnel in Qinling tunnel (Yue Ling section) leading to Hanji Wei Project, this paper introduces the ventilation system. I. Preface In the tunnel construction, in order to dilute and discharge the dust and harmful gas generated by blasting, mechanical operation and so on, keep good air conditions, avoid the occurrence of occupational diseases, poisoning and death and other accidents, speed up the construction progress, ventilation system
