混凝土结构无缝施工技术在工程中的应用

Appliance of Seamless Building Technology of Concrete Constructions in Engineering Project

介绍了超长无缝混凝土结构施工的基本原理。在实际工程施工中 ,利用 U EA混凝土补偿收缩的原理 ,采用膨胀加强带代替后浇带 ,实现了超长钢筋混凝土结构的无缝施工 ,并介绍了在超长无缝混凝土结构中采用膨胀加强带代替后浇带的技术要点 。

The fundamental principle of seamless construction of the super-long structure of reinforced concrete was introduced. In the practice of engineering construction, taking advantage of the principle of compensative contraction of UEA concrete, the expanding and strengthening belt was used to replace the latter cast belt and it realized the seamless construction of the super long structure of reinforced concrete. Through the concrete example, the main points of using the expanding and strengthening belt to replace the latter cast belt in the seamless construction of the super long structure of reinforced concrete were given. It provided the similar engineering construction with referential experiences.
