兰成中贵康县段管道线路在甘肃秦岭山区穿越多处陡坡,陡坡地段表层土为粘性,具有距离长、坡度大等特点,中国石油天然气管道局第三工程分公司针对不同现场条件和不同类型的基岩陡坡情况,在环境差、工期紧、任务重的情况下,结合现有设备,因地制宜,采取简单有效的办法成功穿越了陡坡,保证了工程质量和进度。文章分别介绍了陡坡管道的施工方法。 Lancheng Zhongkang County pipeline section in the Qinling Mountains in Gansu across many steep slopes, steep slopes of the surface soil is sticky, with a long distance, large slope and so on, the China Petroleum Pipeline Bureau Third Engineering Branch for different site conditions and different Type of bedrock steep slopes, in the environment is poor, tight schedule, heavy tasks, the combination of existing equipment, according to local conditions, the simple and effective way to successfully cross the steep slope, to ensure the quality and progress of the project. The paper introduces the construction methods of steep slope pipe respectively.
