超长混凝土结构无缝施工实践

介绍了利用UEA混凝土补偿收缩的原理及UEA加强带的性质,结合具体工程实例,从混凝土试配、筏板膨胀加强带施工、墙体膨胀加强带施工以及楼板膨胀加强带施工等方面探讨了超长混凝土结构无缝施工技术,为类似工程施工提供参考借鉴。

Practice of the jointless construction technology of the super-long concrete structure

The author introduces the principle of the shrinkagecompensating by using the UEA concrete and the properties of UEA reinforcing band.Combined with the concrete engineering example,the author discusses the jointless construction technology of the super-long concrete structure from the aspects of the mixture ratio of the concrete,the construction of the raft expansion reinforcing band,the construction of the wall expansion reinforcing band and the construction of the floor expansion reinforcing band,which provides the reference for the similar project.
