长沙第二电信枢纽楼大体积混凝土施工技术

在长沙第二长途电信枢纽工程3m厚混凝土基础底板的施工过程中,通过运用设置底板滑动层、表面抗裂钢筋、混凝土内部温度钢筋、混凝土材料及配合比的选用、降低混凝土入模温度、保温、保湿、养护等一系列技术措施,保证了该工程3m厚混凝土底板一次连续浇筑平仓到顶的施工质量。

Mass Concrete Construction in Changsha No.2Telecommunication Pivotal Building

In the construction of 3 0m thick concrete foundation base board of Changsha No.2 Long Distance Telecommunication Pivotal Building project, many technical methods were adopted to ensure the construction quality of once continuous pouring and completion of this 3.0m thick concrete base board. These methods include setting up base board sliding layer, surface anti crack reinforcement and concrete interior temperature reinforcement, choosing concrete materials and mixture ratio, decreasing concrete formwork entering temperature, and making thermal insulation and moisture keeping maintenance.
