吊点所用材料应使用直探针（0o）进行100%超声波检测； 所有焊缝吊装前要作磁粉检验,焊接后要做100％UT。
SD-DOP-DPP-ST- 对于吊点的割除，不可用锤击或碳弧气刨方法去除，应使用气割方法在距母材上方5mm处割除，然后用机械方法打磨直至与本体母材光滑平齐，割除后此处需作M.P.I.检验。

4 LIFTING SCHEME吊装过程
4.1
Prefabrication Yard预制场地
Two 600T cranes are used for transportation and prefabrication of EL.(+)45 250 to EL.(+)47 750 OF LQ. The original location of cranes is shown in figure 4.1a. When the panel has been lifted, 370T 1# trailer moves to the place below the panel. Put the panel onto the trailer slowly. The final location of cranes and trailer is shown in figure 4.1b. Before lifting, temporary supports used for transportation are connected with the panel. The location of panels on trailer refers to chapter 4.2.
生活楼5,6层在预制场地的运输及预制均使用2台600T吊车进行，吊车站位如图4.1a所示，甲板片吊起后，370T 1#平板液压拖车移至水平片下方。吊钩下降将水平片缓慢放置到拖车上。装车状态吊机及拖车站位如图4.1b。，水平片在拖车上的位置参见4.2
