空气顶升倒装法安装拱顶油罐,就是利用罐体本身结构条件及密封性能,按倒装顺序将罐体逐圈组焊,密封充气。当罐内空气压力大于被顶升罐体的重量和围板之间的摩擦力时,罐体就被顶升就位,从上到下,依次组焊各带壁板,直至罐体成型。充气顶升时应有严密的统一组织、限位拉杆的顶升高度一定要计算准确、整个安装过程均应注意罐体的整体尺寸形状、充水试验必须始终在有人监督下进行并掌握基础的沉降情况。 Air lift Flip-flops installed vault tank, is the use of the tank itself structural conditions and sealing performance, according to the order of flip-cylinder assembly by ring, seal inflatable. When the air pressure inside the tank is greater than the weight of the tank being lifted and the friction between the coaming, the tank is lifted in place and from top to bottom, the straps are grouped in succession until the tank is formed. Inflatable lift should be closely unified organization, limit the height of the lifting rod must be calculated accurately throughout the installation process should pay attention to the overall size of the tank shape, water testing must always under the supervision of someone and master the basic Sedimentation situation.
