摘要
以北京平乐园保障房项目冬期施工为背景,研究通过提升灌浆施工作业环境温度达到冬期低温条件下进行灌浆施工的可行性,并在北京平乐园保障房项目冬期施工中进行应用,实现在灌浆施工过程中达到预定的施工温度和养护温度标准,确保冬期灌浆达到临界强度前不受冻,突破装配式结构冬期施工技术行业难题,在保证施工质量的前提下大幅缩短施工工期,对冬期装配式结构灌浆施工有一定的指导和推广意义。
Taking the winter construction of the Beijing Pingyuan Paradise Safe Housing Project as the background,the feasibility of grouting construction by raising the ambient temperature of the grouting construction operation to reach the low temperature in winter is studied,and applied in the winter construction of the Beijing Pingyuan Safeguard Housing Project to achieve the grouting construction During the process,the predetermined construction temperature and maintenance temperature standards are reached to ensure that the winter grouting will not be frozen before reaching critical strength.It will break through the difficult problems of the winter construction technology industry of assembled structures and greatly shorten the construction period on the premise of ensuring the construction quality.The grouting construction has certain guiding and promotion significance.
