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。
Fuyin to two junctions gas pipeline Huang Changjiang River through the double-track length of 1687m, across the width of the Yangtze River 1074m. In the design, for the first time, the barbed concrete was used to stabilize the pipe in the Yangtze River crossing project, which simplified the construction process and saved material and investment. Underwater cross-section pipe laying across the riverbed with a full face buried layer, to ensure the safety of cross-section. Since it was put into operation in May 1994, after a flood period, the operation of the pipeline is safe. The project put into operation to ensure the Shanghai Tianhua, Chitianhua and other large chemical fertilizer plants and Huzhou, Zigong, Chengdu gas supply, and promote the development of the national economy.
