Synchronous jacking accurate in-place installation process for large equipment

A synchronous jacking accurate in-place installation process for large equipment comprises the following steps of sequentially arranging a bearing framework and a support framework on a lower layer horizontal sheet; positioning the large equipment on the bearing framework, and installing an upper layer horizontal sheet; installing upper layer equipment of the horizontal sheets; synchronously jacking a hydraulic jack I arranged on the bearing framework until the baring framework and the lower layer large equipment are jacked to the preset height to be loaded; arranging support devices, and placing hydraulic jacks II on the support devices; enabling all the hydraulic jack II to work synchronously; and leading the hydraulic jack I to jack synchronous to enable the lower layer large equipment and the upper layer large equipment to be in butt joint accurately, and installing and dismounting all auxiliary tool facilities. The synchronous jacking accurate in-place installation process for the large equipment can achieve accurate installation of the large equipment, does not be affected and restrained by structural beam distribution of the upper layer horizontal sheet and support mode of the upper layer equipment, and reduces crane using frequency and construction difficulties and risk in lifting the large equipment.
