管板桩油码头水下修补施工技术应用

Application of Underwater Repair Construction Technology for Tubular Piles and Sheet Piles in Oil Terminal

摘要: 在管板桩油码头沉桩施工过程中，当管板桩连接处的锁扣脱落时，需要对空隙处进行水下修补施工处理。以安哥拉渔港成品油库码头与疏浚工程为例，对管板桩油码头水下修补施工过程中的弧形钢板水下安装、水下焊接、水下焊缝防腐等工艺流程进行了研究，制定了有效的施工措施，对同类水下修补施工技术具有重要借鉴意义。

Abstract: In the process of piling with tubular plies and sheet piles in oil terminal, when the locks between tubular plies and sheet piles fall off, and the underwater repair work needs to be carried out on the gaps. By taking the project of product oil depot expansion and dredging of fishing port in An-gola for example, the key processes of underwater welding and underwater weld anti-corrosion are studied, and effective construction measures are formulated, which has important reference significance for similar underwater repair technology.
