目前,我国长距离输送管线一般都采用埋地铺设,管线埋好后覆土填平。其好处是不破坏沿程的天然地貌,不影响农业生产。但是值得注意的是,在地下水位较高的地区还应该考虑水位,管道应避免处于冬夏季节地下水位线变化的范围内,特别是在强腐蚀性的盐碱土壤地区。胜利油田东营到辛店两条并行的输油管线就说明了这一问题。旧胜利线是我国第一条大口径长距离输油管线,于1965年建成投入运行,全长72km,管径Φ426×7;
At present, China’s long-distance transmission lines are generally buried in the laying of pipe buried buried after the fill. Its advantage is not to undermine the natural landscape along the way, does not affect agricultural production. However, it is worth noting that the water level should also be taken into consideration in areas with high groundwater levels. Pipelines should be kept within the range of groundwater level changes in winter and summer, especially in areas with strong corrosive saline soil. Shengli Oilfield Dongying Xin Branch two parallel pipeline to illustrate this issue. The old victory line is China’s first large-caliber long-distance pipeline, put into operation in 1965, a total length of 72km, diameter Φ426 × 7;
