近几年是中国管道施工集中的年份,管道施工过程中隧道穿越也逐步成为穿越的主要方式之一。隧道内管道施工由于其施工空间狭小,施工质量要求高,造成隧道内管道安装难度大。本文以中俄原油管道漠河之大庆段第3标段呼玛河隧道穿越为例对隧道大口径管道安装施工工艺进行研究及实际应用说明。
In recent years, China’s pipeline construction concentrated in the year, the tunnel construction process through the tunnel has gradually become one of the main ways through. Tunnel construction of the tunnel due to its small construction space, high construction quality requirements, resulting in tunnel installation difficult. In this paper, the Sino-Russian Crude Pipeline Mo Da Daqing Section 3 Huamahe Tunnel Crossing as an example of large-diameter tunnel installation and construction technology research and practical application instructions.
