The invention provides stable hydraulic pile driving equipment for buildings. The stable hydraulic pile driving equipment comprises a hydraulic pile driver hammer mechanism and fixing bolts, wherein an oil cylinder piston rod is fixedly connected to the top of the hydraulic pile driver hammer mechanism, the bottom of the hydraulic pile driver hammer mechanism is in contact with a hammer pad, and apile is arranged under the hammer pad; a buffering protection pad with the same diameter as the inner rings of annular pressure blocks is fixedly mounted at the axis of the bottom of an upper pressing plate through two fixing bolts; and a buffering protection pad with the same diameter as the inner rings of the annular pressure blocks is fixedly mounted at the axis of the top of a lower pressingplate through two fixing bolts. The number of the annular pressure blocks is but not limited to eight groups and can be adjusted through increase/reduction. The height of a hollow cavity is changed bychanging the number of the annular pressure blocks, so that a steel wire mesh sleeve is temporarily separated from the bottom end surface of the hollow cavity when a hitting head descends to hit, andthen the top end surface of the hollow cavity exerts a stronger hitting force onto the steel wire mesh sleeve to facilitate improvement of the pile driving efficiency.
