- 摘要:
- 以浙江省镇海炼化—杭州康桥成品油管道工程为例, 详细介绍漂管沉降工艺在管道穿越河流中的应用。其中着重介绍了水下管沟开挖及测量、漂管到位及充水下沉、稳管及管沟回填等施工工艺。该方法的优点是施工简单、造价低、工期短、经济效益显著、不破坏农田, 适用于南方及沿海地区大中型河流的管道穿越
By taking Zhenhai- Hang zhou oil pipeline project as an example,the writer int roduced the river crossing using float ing & sett ling pipeline method,including underw ater trenching, float ing pipeline position measuring, pipeline set tling with filling water,underw ater pipeline stabilizing, underw ater backfilling & some construction cautions etc. This method is suitable for larger or medium river crossing. It has many advantages e.g.const ruct ion simple,cost low,working period short & no- damage to farmland etc.2001,27(27): 48-49 收稿日期：2001-3-19分类号：TE973作者简介：魏广起, 1990 年毕业于中原石油学校, 助理工程师, 现在中原油田建筑集团公司第六工程处从事生产管理工作。通讯地址: 河南省濮阳市, 邮编: 457001, 电话: 0393- 4824680
