“长江口二号”古船迁移保护项目中需使用船坞进行考古作业工作,为此将已废置多年老旧失能坞门的使用功能进行恢复.首先,对失能坞门进行检测,根据检测结果对坞门进行拆除、维修及加固作业.经过修复整备后,失能坞门成功起浮开门,在古船进坞作业后顺利关门落墩止水,为考古工作提供了良好的作业环境.失能坞门恢复启闭功能的工作在国内造船行业属于首创,增加了人们对坞门这种专用设备全生命周期的进一步认识.

In order to use the dock for archaeological work in “Yangtze River Estuary II” ancient shipwreck salvage, the function of the old and disabled dock gate that has been abandoned for many years are restored. In order to resume service, the failure dock gate is tested, and the relevant removal, maintenance, and reinforcement of the dock gate are conducted based on the test results. After repair, the failed dock gate is lifted and opened successfully. After the ancient ship entered the shipyard, the gate closes smoothly, providing a good working environment for archaeological work. The recovery work of the failure dock gate is the first of its kind in the domestic shipbuilding industry. The full life cycle of special equipment such as dock gate is further understood.
