摘　　要：在现浇混凝土施工过程中,虽然其施工工艺和相应的施工技术已非常成熟,但也存在一些因素导致混凝土不能一次性浇筑成型,施工缝设置的好坏影响工程的整体质量,若处理不好施工缝,就会造成建筑结构出现偏差,使施工缝成为整体建筑的薄弱处,对建筑结构的受力、防水等造成影响,降低楼板的使用性能,所以相关施工单位一定要处理好施工缝。本篇文章在查阅大量文献和自身经验基础上对混凝土二次浇筑施工缝所开展的研究,分析了建筑工程混凝土二次浇筑成因、危害以及二次浇筑施工缝的科学处理。最后在理论研究的基础上,以南水北调中线漳古段标为例,对施工缝科学控制及施工技术进行实证研究,以期能为建筑项目混凝土二次浇筑的施工缝处理做参考。In the process of cast-in-situ concrete construction,although its construction technology and corresponding construction technology have been very mature,there are also some factors that lead to the concrete can not be poured and formed at one time.The setting of construction joints affects the overall quality of the project.If the construction joints are not handled well,it will cause the deviation of building structure and make the construction joints become the weakness of the whole building.It will affect the stress and waterproof of the building structure and reduce the service performance of the floor,so the relevant construction units must deal with the construction joints.On the basis of consulting a large number of documents and their own experience,this paper studies the construction joint of concrete secondary pouring,and analyzes the causes and hazards of concrete secondary pouring in construction engineering and the scientific treatment of construction joint of secondary pouring.Finally,on the basis of theoretical research,taking the Zhanggu section of the middle route of the south-to-north water transfer project as an example,this paper makes an empirical study on the scientific control of construction joints and construction technology,in order to provide a reference for the treatment of construction joints in the secondary pouring of concrete in construction projects.
