针对混凝土蒸汽养护时间长、耗汽量大的问题,对露天长线台座进行了改造。采取了热台座和热拌混凝土的干湿相结合的养护方法,使长线台座空心板的养护供气时间由原来的32小时缩短到6小时;台座周转率由原来的48小时缩短到24小时,从而使养护池的生产能力翻了一番。改造后的热养护 For the problem of long steam curing time and large steam consumption, the long-line pedestal was modified. Adopting a combination of dry and wet methods for the maintenance of hot pedestal and hot mix concrete, the long-line pedestal hollow plate curing time was shortened from the original 32 hours to 6 hours; the pedestal turnover rate was shortened from the original 48 hours to 24 hours. As a result, the capacity of the conservation pool has doubled. Retrofit after thermal conservation
