摘要
引汉济渭工程秦岭输水隧洞7#洞主洞工程,由于上游段工期远远滞后,未能按期贯通,造成下游段原设计的通风方案无法实施。文章结合现场实际,在不进行较大调整的情况下,有针对性地对独头掘进7 430 m的通风方案进行了优化,取得了良好效果。
In view of the main tunnel project of No. 7 tunnel for Qinling water conveyance tunnel of Hanjiang - to -Weihe river water transfer project, as the upstream segment failed and was far behind the schedule, the originally designed ventilation of the down - stream segment could not be implemented. In combination with the site condition, the ventilation scheme for single end 7430m development （single heading） was optimized without big adjustment,the way of stage relay air supply was adopted to improve ventilation effect and reduce energy consumption.
