In addition, a disassembly channel is reserved around the installation foundation 1 while the jack 3 is installed, and is used for disassembling the jack 3 after the installation is completed. Then, the size of the large-sized apparatus 1 is measured, a temporary transfer passage is set up from the outside to the installation base surface 2 located indoors according to the size of the large-sized apparatus 1, the temporary transfer passage is to be extended up to just above the supporting plane, and the height of the temporary transfer passage is matched with the height of the supporting plane. When the large scale device 1 is moved to the support plane, the support plane is just in full contact with the bottom of the large scale device 1. Then, a temporary transfer base 4 is placed at the initial end of the temporary transfer channel, traction holes are reserved at the front end of the temporary transfer base 4, and at least four sets of rolling devices 19 are symmetrically installed on the left and right sides of the bottom of the temporary transfer base 4. Next, an electric hoist 5 is mounted on the temporary transfer channel 4, the tail of the electric hoist 5 is fixed on the traction hole by using a steel wire rope 6, and the head of the electric hoist 5 is hung at the tail end of the temporary transfer channel 4. After the preparation work is finished, the large-scale equipment 1 is hoisted to the temporary transferring base 4 by using a crane, and the azimuth of the large-scale equipment 1 is adjusted, so that the situation of tilting to one side is prevented. After the inspection is completed, the electric hoist 5 is started, the electric hoist 5 pulls the temporary transfer base 4 and the large-scale equipment 1 to the position right above the supporting plane, and in the pulling process, the posture of the large-scale equipment 1 and the temporary transfer base 4 at an offset angle are concerned at any time, whether sinking, tilting and other phenomena occur is observed, and the adjustment is timely carried out. When the large-scale equipment 1 is transferred to the position right above the supporting plane, the electric hoist 5 is closed, and part of the temporary transfer channel 4 positioned around the supporting plane is removed, so that the large-scale equipment 1 is completely placed on the supporting plane, and at the moment, the position condition of the large-scale equipment 1 is checked, and the inclination is prevented. Then, all the jacks 3 are started, the large-scale equipment 1 is slowly put down until being completely placed on the installation foundation surface, after the large-scale equipment 1 is confirmed to be completely in place, a plurality of the jacks 3 are removed from the disassembly channel, the disassembly channel is buried, and the installation of the large-scale equipment 1 is completed in place.
