摘　　要：岳阳长岭炼化港口部码头提质改造工程自进入11月份以来,受天气和温度等因素影响,预制空心板在施工过程中出现强度上升缓慢、部分构件出现细微裂缝等问题,严重影响施工工期和构件质量。针对上述问题,对提高预制构件在施工过程中强度上升速率和构件质量的方法进行研究,通过采用蒸汽养护技术分别进行对比试验。结果表明,蒸汽养护技术能够有效提升预制构件在生产过程中的强度上升速率,降低构件裂缝出现的频率。蒸汽养护技术在类似预制构件生产过程中能够起到提高强度上升速率、提高构件产品质量和降低废品损耗率等效果,从而有效节约工期、降低成本。Since November, due to the influence of weather and temperature, the strength of prefabricated hollow slabs of the wharf upgrading project of Yueyang Changling Refining and Chemical Port Department rise slowly, and cracks appear in some prefabricated hollow slab, which seriously affect the construction period and the component quality.Aiming at these problems, this paper studies the method of improving prefabricated strength rising rate in the process of construction and the component quality, and carries out means of steam curing technology contrast experiment respectively. The results show that the steam curing technology can effectively improve prefabricated in the rate of strength rise in the process of production and reduce the components of the occurrence of cracks.The steam curing technology can improve the rate of strength rise and the quality of components, and reduce the waste loss percentage in the production process of similar prefabricated components, so as to effectively save the construction period and reduce the cost.
