Reinforcing structure based on old workshop infrastructure construction and construction method

The invention discloses a reinforcing structure based on old workshop infrastructure construction and a construction method. The reinforcing structure comprises an original foundation mechanism, wherein an original foundation beam is vertically arranged on the upper surface of the original foundation mechanism, original bearing platform cast-in-place piles are respectively embedded into the lowersurfaces of both sides of the original foundation mechanism, new foundation bearing platforms are respectively arranged on the both sides of the original foundation mechanism, and new steel pipe pilesare respectively embedded into the lower surfaces of the two new foundation bearing platforms. The reinforcing structure based on the old workshop infrastructure construction and the construction method relates to the technical field of workshop reconstruction. An anti-seismic piece is arranged on an original foundation bearing platform, so that if an earthquake occurs after a workshop is transformed, a good buffer anti-s
