大底盘地下室底板跳仓法应用案例分析

Aapplication case of alternate segment concrete pouring method for basement floor with large chassis basement

某大底盘地下室为超长地下室。原施工图设计采用后浇带将地下室分为多个区块。地下室体量大,后浇带数量多,对施工管理、进度的控制造成一定困难。经综合比较,本工程地下室底板用跳仓法技术替代后浇带。介绍了本工程地下室底板跳仓法施工技术实施的具体施工方案、相关措施以及底板在施工阶段温度应力分析。

A large chassis basement was a ultra-long basement. In the original construction drawing design, the basement was divided into multiple blocks by post-pouring belts. The basement was large and ultra-long. Many post-pouring belts were arranged on the bottom plate. It was difficult to control the construction management and progress. After comprehensive comparison, the post pouring belts were replaced by alternate segment concrete pouring method in basement floor in this project. It introduced the concrete scheme of alternate segment concrete pouring method in this project and the analysis of temperature stress of basement floor in the construction stage.
