截至1月18日,管道公司承建的中俄二线管道焊接已突破500 km。中俄原油管道二线是深化中俄两国在能源领域合作的重大工程。管道全长941 km,计划2017年10月具备投产条件,2018年1月1日投入运营。中俄二线施工区域大部分分布在北纬52度以上的高寒地区,经过460 km永冻土区,240 km爆破段,还有近60 km的沼泽地带。极端寒冷的天气和复杂的地质条件,对工程进度和施工人员都是极大的挑战。 As of January 18, China-Russia second-tier pipeline construction by pipeline companies has exceeded 500 km. The second line of Sino-Russian crude oil pipeline is a major project to deepen the cooperation between China and Russia in the energy field. The pipeline is 941 km in length and is planned to be put into operation in October 2017 and put into operation on January 1, 2018. Most of the second-line construction areas in China and Russia are located in the alpine region above 52 degrees north latitude, after 460 km of permafrost zone, 240 km of burst section and nearly 60 km of swamp zone. Extremely cold weather and complex geological conditions are a great challenge to the progress of construction and construction workers.
