中俄原油管道漠大线为国家重点工程,为保护大兴安岭生态环境和永冻土层,要求永冻土地区在寒季施工,其中漠河县年平均气温-4℃,最低温度达到-52.3℃,是首次在高纬度及高寒地区进行冬季施工,如何保障严寒环境温度下顺利施工成为工程一大难点,本文主要从人员和设备管理方面叙述了漠大线冬季施工采取的保障措施,采用新技术对设备进行改造,提升冬季施工能力,积累了严寒环境下宝贵施工经验。 In order to protect the ecological environment and permafrost in Daxing’anling, permafrost regions are required to be constructed in cold season. The annual average temperature in Mohe County is -4 ℃ and the minimum temperature reaches -52.3 ℃, It is the first time to carry out winter construction in high latitudes and alpine regions. How to ensure the smooth construction under severe cold temperatures has become a major difficulty in engineering. This paper mainly describes the safeguard measures adopted in winter construction of the Great Wall from the aspects of personnel and equipment management, and adopts new technologies Equipment to transform and enhance the winter construction capacity, has accumulated valuable experience in the cold environment of the construction.
