连续式膨胀加强带代替伸缩后浇带施工工艺

Construction Technology of Continuous Expansion Strengthening Belt Instead of Telescopic Post-casting Belt

指出了按照传统技术施工,由于伸缩后浇带封闭时间间隔长,导致后期清理困难、支撑体系保留时间长、钢筋易锈蚀,对工程质量、进度与成本有很大影响,且留下渗漏的隐患。以上海市一工程为例,阐述了采用内掺HEA抗裂防水剂连续式膨胀加强带代替伸缩后浇带的原理及技术要点。以供参考。

According to the traditional technology construction,there is a long sealing time interval after the expansion and contraction.The later cleaning is difficult;the support system has a long retention time and the steel bar is easy to rust,which has a great influence on the quality,progress and cost of the project,and leaves a hidden danger of leakage;Taking a project in Shanghai as an example,this paper expounds the principle and technical points by using the continuous expansion reinforcing belt with HEA anti-cracking waterproofing agent instead of telescopic post-casting belt.
