摘要
为解决单斜井双正洞多开挖面平行施工通风难题,介绍一种新型隧道施工隔板风道通风技术,通过对该项技术通风原理、布置方式、适用条件和操作要点等进行分析,发现其在通风系统设计计算方面的特殊性,并举例重点阐述该通风技术的计算分析过程,提出合理的计算分析方法,证明其节能优势,总结出该通风技术的优越性,为该项技术在推广应用中的方案设计与优化提供技术支持。
There is great difficulty in the ventilation during one single inclined shaft. A new technology for ventilation tunneling at multiple faces of twin-tube tunnel accessed from through air channel formed by false ceiling is presented. The ventilation principle, layout mode, applicable conditions and key operation points of the mentioned ventilation technolo- gy are presented. The calculation and analysis of the ventilation technology is presented with emphasis. Rational calcula- tion and analyzing method is proposed, which demonstrates that the mentioned ventilation technology has advantage in energy-saving. The superiorities of the ventilation technology are summarized. The paper can provide technical reference for the design and optimization of ventilation technology in the future.
