Case Study on Construction Ventilation Technology for High Gas Work Lot of Sanlian Tunnel

Yin Dongmei

Abstract

Efficient and energy-saving construction ventilation scheme can not only guarantee the construction safety of high gas tunnels,but also can reduce the construction cost.For the case of the high gas work lot of Sanlian tunnel,the possibility of natural ventilation is studied,different ventilation schemes are analyzed,different ventilation arrangement modes are investigated and,in the end,the mode of natural ventilation and gallery ventilation with jet flow is adopted.The paper can be served as reference for similar projects in the future.
