两安特长隧道高地温条件下施工通风技术研究

Study on the Construction Technology of Liangan Tunnel Ventilation and High Temperature Conditions

以贵广客运专线两安特长隧道施工为背景,对高地温条件下特长隧道施工通风进行研究。随着洞深增加,温度不断升高,洞内施工作业环境急剧恶化,在施工过程中,结合工程实际,分阶段进行了施工通风设计,并不断进行优化设计,加强通风排烟效果,不断改善洞内施工作业环境,并在反复的施工实践中总结出科学有效的特长隧道施工通风技术和合理的设备配置,以期为类似工程施工提供可借鉴的经验。

Take the long tunnel construction as the background, study on the construction of extra long tunnel under the conditions of high temperature and ventilation. With the increase of the hole depth, the temperature rising, the rapid deterioration of environment construction, in the construction process, it combined with the engineering practice, the design of construction ventilation in stages, and optimize the design of ventilation and strength the smoke exhaust effect, improve the working environment, and summed up the scientific and effective tunnel construction ventilation technology and reasonable the equipment in the construction of repeated practice, in order to provide a reference for similar engineering construction.
