摘　　要：结合青岛港某港区粮食筒仓工程滑模施工,以筒仓液压滑模施工工艺为出发点,重点介绍本工程中滑模系统组成、滑模施工工序及质量控制措施。本工程液压滑模系统由液压提升系统、模板系统和操作平台系统3部分组成,采用56台GYD60型滚珠式千斤顶同步顶升,总起重量为3360kN,滑模提升总重设计值为2275kN,滑模系统的顶升能力可满足工程滑模施工要求;滑模施工工艺主要分初滑、正常滑升和末升3个阶段,在滑模提升架安装位移传感器,监测滑升过程中平台水平位移,滑升过程中沿筒仓半径、切线方向位移均<3mm,小于规范允许值,证明滑升过程中平台处于平稳状态,采取的防纠偏措施到位,且能保证仓壁混凝土浇筑尺寸偏差控制在允许值内。Combined with the slipform construction of a grain cylindrical silo project in a certain port area of Qingdao Port,this paper takes the hydraulic slipform construction technology of cylindrical silo as a starting point,focuses on the slipform system in this project,the composition of the system,slipform construction process and quality control measures.56 GYD60 ball jacks are used to synchronize the lifting of the formwork.The total lifting capacity is 3360kN,and the total weight of slide mold lifting design value is 2275kN,the jacking capacity of the slipform system can meet the requirements of the project slipform construction.The slipform construction process is mainly divided into three stages which are initial slip,normal slip and final rise,displacement sensors are installed in the slipform lifting frame to monitor the horizontal displacement of the platform during the sliding process.The displacement along the radius and the tangential direction of the silo during the sliding process is less than 3mm,which is less than the permissible value of the specification,which proves that the platform is in a smooth state during the sliding and lifting process,and the anti-deviation measures taken are in place to ensure that the deviation of the concrete casting dimensions of the silo wall can be controlled within the permitted value.
