摘要
京沪高铁喷涂聚脲防水施工在2009年冬季进行了大量的试验:不同的养护条件及时间对聚脲涂层与混凝土基层的附着力的影响。根据试验结果,采取了棚内升温保温作业及棚内养护涂层7 d的冬季施工措施。
Many experiments for SPUA waterpoofing project of Beijing-Shanghai express railway were performed to explore the influence of curing conditions and curing time on the adhesion between the SPUA coating and concrete base in winter,2009.Based on the results,winter construction measures taken in the project include curing SPUA coating elements in a shed with temperature above 10 ℃ for no less than 7 days.
