摘要
长距离通风一直是困扰长隧洞施工的一个难题。对锦屏二级水电站4#引水隧洞通风系统在运行过程中遇到的问题进行了分析,优化调整了掘进初期的通风方案。优化后的方案基本解决了掌子面污浊空气无法排出、新鲜风与污风相互干扰的问题,提高了风压及进风量,为引水隧洞的施工创造了有利条件。
The long distance ventilation is one of the main problems in long tunnel construction. The author analyzed the ventilation problem in the 4th tunnel of Jinping Hydropower Station and optimized the original solution. After optimization, fresh air circulation in tunnel face was improved and so did the wind pressure and air intake volume. The cross term interferences between stale and fresh air was decreased. This application created favourable conditions for the construction.
