This article takes the winter construction of precast concrete box girders of Cheng Hute Bridge in Changjia expre-ssway as an example and introduces the health maintenance process of precast concrete box girder by using the electric he-ating steam generator to supply heat combines with greenhous-es heat storage method. This box girder appearance of health maintenance technology has no crack with fast and stable stre-ngthen concrete so as to ensure the construction progress and good prefabricated effect.
