When using jacks, they can be divided into two groups, and the lifting construction can be carried out in turn. That is, after the first group of jacks is completed and one is formed, the second group of jacks foot pads are supplied with oil to apply the lifting force, and then the first group of jacks is returned. Unloading shall be carried out in sequence. This can prevent the jack from causing vibration to the upper building at the same time. When lifting, all jacks must be kept synchronized, with each lifting stroke for construction.

During the implementation of the overall boom, the application of force at each action point of the external force should be observed and recorded. According to the change of the external force, judge whether there is any abnormality during the jacking. At the same time, use a ruler and Theodolite to monitor the deviation of the building during the jack jacking process. Use leveling observation to monitor the settlement. Strengthen the observation of the upper structure, and find out if there is any potential safety hazard, even if effective measures are taken to eliminate it.
