结构自防水和超长结构无缝连续施工技术在天津荣畅园地下工程中的应用

Application of Concrete Structure Self-Waterproofing& Super Long Structure Continuous Seamless Construction Technique in Tianjin Rongchang Garden Underground Garage

天津荣畅园地下工程使用混凝土结构自防水和超长结构连续施工技术。优选限制膨胀率0.05%以上的高性能膨胀剂,通过优化设计补偿收缩混凝土,合理设置膨胀加强带、取消温度后浇带,注重混凝土浇筑、振捣、养护工作,简化施工工艺,显著加快施工进度。

Concrete structure self-waterproofing & super long structure continuous seamless construction technique is used in Tianjin Rongchang garden underground garage. High performance expansive agent for concrete with restrained expansion rate ≥ 0.05% is selected. Shrinkage compensating concrete is optimized. The post-pouring belt is reasonably optimized by expansion reinforcing band. concrete construction, vibration, and curing are also get enough attention. Construction craft is simplified, and the schedule of construction is also effectively accelerated.
