珠海口岸广场工程由于结构巨大 ,后浇缝总长约2300m ,采用UEA混凝土减免后浇缝的设计施工专利技术 ,以膨胀加强带替代后浇缝 ,通过调整UEA掺量设计混凝土膨胀率 ,施工时采用间歇式无缝施工法。经质检部门检验 ,结构各部位混凝土质量全部达到设计要求。
The Zhuhai Port Square project has a huge structure, and the total length of the back-seam joint is about 2300m. The patented technology for the design and construction of the UEA concrete post-reduction joint is adopted. The expansion joint is used to replace the post-seam joint. The expansion rate of the concrete is adjusted by adjusting the UEA content. Intermittent seamless construction method. After inspection by the quality inspection department, the concrete quality of all parts of the structure has reached the design requirements.
