Prefabricated concrete structure sleeve grouting construction method under low-temperature condition
The invention discloses a prefabricated concrete structure sleeve grouting construction method under the low-temperature condition, and belongs to the technical field of prefabricated concrete structures. On the basis of a pre-curing method, the cavity internal temperature and the environment external temperature are taken as temperature control measures, the freezing critical strength and the disturbance strength are taken as strength control criteria, and the prefabricated concrete structure sleeve grouting construction method under the low-temperature condition is formed. The prefabricated concrete structure sleeve grouting construction method comprises the following steps of construction preparation, prefabricated wall column installation, bin separation and bin sealing, pre-maintenance device installation, grouting temperature control, grouting material preparation, grouting construction, maintenance and low-temperature sleeve grouting construction quality evaluation. According to the prefabricated concrete structure sleeve grouting construction method under the low-temperature condition, the requirement for winter low-temperature construction is met, and the limitation of prefabricated building sleeve grouting connection on winter low-temperature construction is broken through.
本发明公布一种低温条件下装配式混凝土结构套筒灌浆施工方法，属于装配式混凝土结构技术领域。基于预先养护方法，以腔体内部温度、环境外温度作为温控措施，以受冻临界强度和扰动强度作为强度控制准则，形成低温条件下装配式混凝土结构套筒灌浆施工方法，包括以下步骤流程：施工准备→预制墙柱安装→分仓与封仓→安装预养护装置→灌浆温度控制→灌浆料制备→灌浆施工→养护→低温套筒灌浆施工质量评价。本发明满足冬期低温施工的需求，打破了装配式建筑套筒灌浆连接受冬期低温施工的限制。
