摘要
以泰瑞城项目一标段样板试验区装配式预制墙体套筒灌浆冬期施工为例,进行预制墙体套筒灌浆的实体试验研究,结合试验原理、试验准备、试件制作及试验数据的采集和分析,总结出在预制墙或预制柱底部接缝位置埋设发热导线进行加热养护的施工方法,以保证装配式建筑预制墙体或预制柱套筒灌浆连接部位的施工质量。
Taking the winter grouting construction of prefabricated prefabricated wall sleeve in the sample test area of the first section of Tairuicheng Project as an example, the solid test research of prefabricated wall sleeve grouting was carried out.Combining the test principle, test preparation, test piece production and test data collection and analysis, the construction method of heating and curing was summarized by burying heating wire in the bottom joint of prefabricated wall or prefabricated column, which can ensure the construction quality of the grouting connecting parts of the precast wall or the precast column sleeve of the prefabricated building.
