摘要
三峡升船机为国内首次采用的齿轮齿条爬升式垂直升船机,是世界上规模最大、技术难度最高的升船机。升船机施工采用了许多新设备、新技术、新工艺,对确保升船机施工质量、施工进度、施工安全起到了至关重要的作用。介绍了塔柱结构混凝土施工方案、温度控制措施、施工期变形分析及施工精度控制措施、承船厢安装方案等关键性技术问题的研究,结合施工实践对上述关键技术实施效果进行了分析。
The ship lift of TGP is a gear-rack climbing type of vertical ship lift,which was firstly adopted in China and was the largest and most difficult ship lift in the world.Many new devices and techniques were adopted to ensure the quality,progress and safety of the construction of ship lift.We introduced the key technical issues such as construction scheme of concrete tower structure,temperature control measures,measures of deformation analysis and precision control in the construction period and installation scheme of ship chamber.The implement effects were analyzed combining with the practical construction.
