Disclosed is a jack synchronously and electrically driven. An electric device (3) is arranged on the portion of a starting rod (2) of the jack (1), and is of a reciprocating rotary motion structure; in the using process, the electric device (3) pushes the starting rod (2) to do reciprocating motion, and pressurizing work is carried out on the jack; a limiting device (4) is arranged and automatically controls the lifting limit position of the jack; an electronic monitoring system (5) is arranged to remotely monitor the jacking state, and observes the situation on site through a monitor (6); a pressure detection module (7) is arranged to detect pressure borne by various jacks; and a jack pressure bearing block (8) is additionally arranged so as to ensure stability and balance of a foundation in the using process of the jack; and lifting of the jack is carried out through electric power, manual work is relieved, and the work efficiency is improved.
