- 摘要:
- 陕京二线输气管道工程的部分标段位于黄土塬地区,该地区地形复杂,地势险峻,主要由冲沟和黄土坡组成,施工作业场地狭小,如果采用大开挖法施工,不仅对环境、植被破坏大,土方量大,而且地貌恢复和水工保护也相当困难,为此采用斜井穿越法进行施工。文章介绍了斜井穿越法的施工技术措施,该方法解决了传统大开挖法存在的许多问题,具有明显的安全和环保优势,是大中型冲沟、台地、黄土坡地区管道施工的有效方法。
Some bid sections of the Second Shan-Jing Gas Pipeline Project are located at loess plateau of complicated and rugged terrain mainly consisted of gullies and loess sloping fields. At such narrow construction sites, the oblique well crossing method is adopted for minimizing the hazard to environment and vegetation. This paper describes the constructional technique of the oblique well crossing method. The method settles many constructional and social problems existing in a traditional large scale excavation method. It possesses predominance of safety, economization and environmental protection, and is an effective method for pipeline construction in the areas with large and medium gullies, mesas and loess sloping fields.2007,3(3): 23-25 收稿日期：2006-8-8分类号：TE973.4作者简介：梁国俭(1968-),男,辽宁锦州人,工程师,1995年毕业于河北廊坊管道局管道职工学院,现从事管道施工技术工作。
