辽河油田的兴隆台—鲅鱼圈轻烃管线工程的大辽河穿越工程于1988年11月13日下午完成穿越施工,符合设计要求。大辽河穿越段水平长度1136m,并列两条φ219管线,管道防腐方式为无溶剂重防腐。该工程使用引进的美国里丁贝茨公司的RB-5型大型专用水平定向钻进行河床下穿越。施工所采用的同孔双管并拖新技术,一次穿越两条管线, The Liaohe River crossing project of Xinglongtai-Bayuquan light hydrocarbon pipeline project of Liaohe Oilfield completed the crossing construction on the afternoon of November 13, 1988, meeting the design requirements. The Liaohe River transverses the horizontal length 1136m, two φ219 lines in parallel, the anticorrosive way of the pipeline is non-solvent heavy antiseptic. The project uses the introduction of the United States Ridge Betz’s RB-5 large-scale special-purpose horizontal directional drilling riverbed crossing. The construction of the same hole with two new technology drag and drop, one through two pipelines,
