- 针对解决现役管道埋深不足问题的沉管技术已经在国内得到广泛的应用,文章介绍了该技术的特点和应用范围、沉管设计中关于最小管沟长度、管道沉降量和允许跨度等参数的计算方法以及具体的施工步骤、施工技术和安全措施。
The sinking pipe technoigue for solving inadequate buried depth of an active pipeline is widely used in China. The features and application range of this technique as well as the design parameter calculations including minimum length of pipeline ditch, pipeline settlement, permitted span are presented in this paper. Also, the concrete construction process, construction techniques and safety measures are illustrated.2008,3(3): 64-66 收稿日期:2007-11-2分类号:TE973作者简介:刘刚(1979-),男,河北保定人,助理工程师,2002年毕业于北京工业大学交通土建专业,主要从事长输管道线路和穿跨越设计工作.参考文献:
