用膨胀混凝土加强带取代后浇带的施工方案的研究与应用

Study and Application of the Construction Scheme of Replacing the Post Pouring Belt with the Expansive Concrete Reinforcing Belt

在金鹿尚居(二标段)工程中采用了膨胀混凝土加强带取代后浇带的施工方案,利用膨胀带的补偿收缩原理,实现了筏板基础混凝土的连续浇筑,不但增强了混凝土的密实度,确保了混凝土结构的抗裂防渗功能,而且缩短了工期,降低了工程成本,取得了良好的经济效益和社会效益。

The construction scheme of replacing the post pouring belt with the expansive concrete reinforcing belt was adopted in Jinglu Shangju Projec（tthe second bid section）, by using the compensating shrinkage principle of the expansive concrete reinforcing belt, the continuous pouring of raft foundation concrete was realized, which not only enhances the compactness of the concrete and ensures the crack resistance and seepage control functions of the concrete structure,but also shortens the construction period and reduces the cost of the project,achieving good economic and social benefits.
