- 黄河三角洲胜利孤东油田北海堤需要加固维修,针对黄河三角洲海域的气象、水文、地质条件,分析了3种海上沉桩施工方案的可行性,最终选择了振动锤双体打桩船沉桩方案。文章重点介绍了振动锤打桩船沉桩施工的工艺流程、施工方法及步骤,总结了500m试验段的施工效果,提出了秋冬季海上打桩的有效措施。实践证明,在风力小于5级的情况下,采用120kW振动锤双体打桩船沉桩,速度快,质量好。
The northern sea wall in Gudong Oilfield at Yellow River Delta needed reinforcing so that the feasibility of three kinds of offshore driving pile construction methods was analyzed in consideration of the sea conditions of weather,hydrology and geology in Yellow River Delta area.Finally the driving pile construction scheme using vibrating hammer and piling catamaran was chosen.This paper focuses on the construction process, method and steps of pile driving using vibrating hammer and piling catamaran,summarizes the construction effect of 500m long test sea wall,puts forward effective measures of offshore piling in winter and autumn.The practice proves that for wind scale less than 5,using 120 kW vibrating hammer and catamaran for pile driving is fast with good quality.2008,1(1): 27-30 收稿日期：2007-10-29分类号：U656.2作者简介：姜则才(1966-),男,山东荣城人,高级工程师,1987年毕业于大连工学院,现任胜利油田胜利工程建设集团有限责任公司第二工程处经理,从事海洋工程的施工管理工作.参考文献：
