摘要:
为了解决特长隧道施工通风难题,以安琶特长隧道施工通风为实例,对不同阶段的施工通风方式,隧道施工通风需风量计算和自然风压计算; 对有利自然风压条件下射流增压需求进行了分析,并对射流巷道式通风应用效果进行了检验。结果表明: 采用射流巷道式通风,能满足特长隧道不同阶段的施工通风需求; 充分利用有利自然通风条件,能减少射流风机配置,节约成本,减少能耗。
关键词: 特长隧道, 施工通风, 射流通风, 自然通风
Abstract:
In this paper, analysis is made on the ventilation modes for different construction phases, air volume calculation, natural air stress calculation, and air pressurizing under natural air, and the effect of jet ventilation is testified, with the ventilation of AngrenPap superlong tunnel as an example. The results show that jet ventilation mode is rational and can meet construction requirements very well.
Key words: AngrenPap railway tunnel, construction ventilation, jet ventilation, natural ventilation
