The invention provides a foundation building error correcting and reinforcing mechanism. The foundation building error correcting and reinforcing mechanism includes a pedestal, wherein the top of thebase is welded with a housing; two sides of the housing are equipped with through holes; a slide groove is formed in the inner wall of the through holes at two sides of the housing; the inside of theslide groove is in sliding connection with a first screw and a second screw; the other end of the first screw is welded with a connecting bar, and the other end of the connecting bar is welded with one end of the second screw; one end of the second screw is welded with a fixed block; one side of the inner wall of the housing is welded with a cooperation rod; a fixed block is arranged at one end ofthe cooperation rod; and the outer side of the first screw is in threaded connection with a screw block. The foundation building error correcting and reinforcing mechanism can preferably detect the curved part of a wall and then suitably adjust the curved parts so as to detect whether the bending speed of the wall is high.
