某大型商贸中心项目5万m^2混凝土底板施工技术要点

The Construction Technique Key Point of 50000 Square Meters Concrete Baseboard in a Large Business Center Project

某项目5万m2大面积地下结构底板,板块划分多,单次连续浇筑面积大、浇筑时间长,加上如承台等局部增厚部位,其混凝土施工具有与大体积混凝土相似的特性,为防止开裂渗漏,在施工质量、工期和成本控制方面采取了一系列技术措施,供同行参考。

A project area of 50000 square meters large floor underground structure,multi-segmentation,a single continuous pouring of large,long casting time,such as local thickening plus caps and other parts,which have a large volume concrete construction concrete similar characteristics,to prevent cracking leakage,construction quality,schedule and cost control has taken a series of technical measures for reference.
