三峡升船机塔柱高空作业升降平台研究与应用

Research and application of aerial comprehensive lifting platform of tower column of Three Gorges Project ship lift

在三峡升船机续建工程中,因总体施工程序的调整,形成了塔柱筒体与齿条、螺母柱、平衡重、纵导向导轨等部位多重立体交叉施工作业的情况。在常规排架方案不能满足施工需要的情况下,研究并实施了可满足不同部位、不同工序、可迅速垂直转换施工部位的高空综合作业升降平台。该平台包括卷扬提升升降平台、齿轮齿条升降平台、吊挂升降平台等几种类型,可满足升船机金属结构埋件安装、二期混凝土施工、机电设备安装、二期混凝土浇筑、pagel灌浆等施工作业的需要,大大缓解了机电工程、金属结构工程施工工期紧张的情况。本项技术经过适配性设计后,可推广应用于水工建筑各种类型垂直导向快速施工的高空作业中。

The overall construction program has been changed in the extension project of Three Gorges Project ship lift. Because of it, the tower column, rack, nut post, counterweight, and longitudinal guide rail should be constructed at the same time which forms the grade separation operation. In this case, conventional shelving scheme can not meet the requirement of construction. So the aerial comprehensive lifting platform is adopted which can quickly change the vertical construction site and meet the requirements of different parts and working procedures. This platform contains hoist lifting platform, gear-rack lifting platform, and hanging lifting platform. Comprehensive lifting platform can meet the requirements of the installation of metal structure, con-struction of second stage concrete, installation of mechanical and electrical equipment, concrete pouring of second stage concrete, and pagel grouting. It can relief the intense construction period. This technique after design can be popularized and applied in similar project.
