The invention discloses a micro pile stand column comprehensive reinforcing system with an optimized existing supporting structure and a construction method. The micro pile stand column comprehensive reinforcing system is used for reinforcing an existing stand column and comprises a plurality of steel pipe piles evenly distributed around the stand column; the steel pipe piles are divided into more than one ring and evenly distributed around the stand column. Longitudinal stiffened plates are arranged between each steel pipe pile and the corresponding stand column or between the steel pipe pile and the other steel pipe pile, located in the same radius direction, in the other adjacent ring of steel pipe piles. The plurality of steel pipe piles are provided with a plurality of transverse stiffened plates along the vertical direction; all the fan-shaped plate units of each transverse stiffened plate are spliced into a polygon, wherein an inner hole of the polygon is matched with the cross section of the stand col
