摘要:
采用并联风管对2个开挖面同时进行送风时,隧道施工通风系统中风管三通设置的位置对风管出口风量的影响较大,利用理论计算得出主风管与分风管直径的比值是分风三通设置位置对开挖面风管出口风量影响的关键因数,围绕着理论计算结果例举3个工程算例及1个工程实例进行了验证,得出合理选择分风三通的位置来提高风管出风口风量的方法,为采用分风三通的施工通风工程提供技术参考。
关键词: 隧道, 施工通风, 分风三通
Abstract:
The influence of location of ventilation Tjunction for tunnel construction on the air volume of ventilation pipe is serious; It is illustrated that the ratio of main ventilation pipe diameter to subventilation pipe diameter is the main factor for determining the location of ventilation Tjunction. Three calculation cases are given, of which the calculation results are compared with an actual project. Finally, rational locations of ventilation Tjunction are obtained.
Key words: tunnel, construction ventilation, ventilation Tjunction
