If several prestressed hydraulic jacks are required to lift at the same time, in addition to placing the prestressed hydraulic jacks correctly, multi-top diverter valves should be used, and the load of each hydraulic jack should be balanced, and attention should be paid to keep the lifting speed synchronous. It is also necessary to consider the possible subsidence of the ground due to uneven weight, so as to prevent the danger of being tilted due to the weight being lifted.
