摘要
本文以常嘉高速澄湖特大桥预制箱梁冬季施工为例,介绍了采用电加热蒸汽发生器供热结合暖棚蓄热的方法,进行预制混凝土箱梁的养生工艺。该法养护施工的箱梁外观无裂纹,混凝土强度形成快速、稳定,确保了工期的进度,预制效果良好。
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.
