摘要
佛阴至两路口输气管线黄长江穿越复线工程全长１６８７ｍ，穿越长江水域宽度１０７４ｍ。设计中，首次在长江穿越工程采用装配式重晶石混凝土加重块稳管，简化了施工工艺，节约了材料和投资。水下穿越管线采用全断面沟埋敷设于河床稳定层内，确保了穿越管段的安全。１９９４年５月投产运行以来，经过一个洪水期的考验，管道运行安全良好。该工程的建成投产保证了沪天化、赤天化等大型化肥厂和沪州、自贡、成都地区的供气，促进了国民经济的发展。
The overall length of crossing Changjiang Rive at Huangqian of the double gas pipelines from Fuyin to LiangLukou is 1 687 m and the width of crossing water is 1 074 m. Underwater pipeline stabilizing has first made with assembled barite concrete weighted books, which simplified construction technology and economized raw materials and cost. The under water pipelines were laid into the stable bed by ditch burying of full cross-sectional area to ensure the safety of underwater pipelines. Since putting into production in May, 1994, the pipelines has withstood the lashes of a flood stage. The pipelines has ensured the gas supplying of Luzhou Natural Gas Chemical Plant, Chishui Natural Gas Chemical Plant. Luzhou, Zigong and Chengdu.
