Tank wall dismantling process for large storage tank
The invention discloses a tank wall dismantling process for a large storage tank. The dismantling procedure comprises the steps that a scaffold is erected on the outer side of the storage tank; a heatpreservation layer of the storage tank is dismantled; a door opening is formed in the tank wall; floating cabins in the tank and accessories on the outer side of the tank wall are dismantled; and thetank wall and the scaffold are dismantled through zoning and circle dividing rolling operation. According to the tank wall dismantling process, while safe dismantling of the tank wall of the large storage tank is guaranteed, resources can be utilized to the maximum extent, the construction period is shortened, the efficiency is improved, construction operation safety can be guaranteed, and the residual value of tank wall plates is increased; in specific implementation, rolling operation is conducted in zoning and circle dividing modes from top to bottom, and the wall plate in each area is ina rolling management state all the time from cutting to hoisting; and the tank wall dismantling process can be applied to dismantling construction of large cylinder or cylinder-like static equipment in the petrochemical industry and has a large application range and great popularization value, by implementing the tank wall dismantling process, improvement of the technical level of storage tank dismantling construction is greatly promoted, the utilization rate of construction machines and tools is increased, and good social benefits and economic benefits are certainly brought.
本发明公开的大型储罐罐壁拆除工艺，拆除流程为：储罐外侧搭设脚手架——拆除储罐的保温层——罐壁开设门洞——拆除罐内浮舱及罐壁外侧的附属物——分区域、分圈滚动作业拆除罐壁及脚手架。本发明在确保大型储罐罐壁安全拆除的同时，可最大程度利用资源，缩短工期，提高效率，并能保证施工作业安全，提高罐壁板残值；在具体实施中，本发明分区域、分圈、自上而下进行滚动作业，对每个区域的壁板自切割到吊装，始终处于滚动管理状态；本发明可应用于石油化工行业大型圆筒或类圆筒式静设备的拆除施工，具有较大应用范围和极大推广价值，其实施将极大促进储罐拆除施工技术水平的改进和提高，提升施工机具利用率，必将带来良好的社会效益和经济效益。
