Hydraulic Slipform Construction Technology and Intelligent Monitoring of Grain Cylindrical Silo
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 3 360kN,and the total weight of slide mold lifting design value is 2 275kN,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 3 mm,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.
