王快水库溢洪道宽缝混凝土施工新技术应用

The application of construction technique in wide slit concrete of spillway in Wangkuai reservoir

王快水库除险加固工程根据进度要求,在溢洪道宽缝施工中首次采用幕湖牌302混凝土界面处理剂和掺加UEA型混凝土膨胀剂新技术,提前进行了宽缝二期混凝土的回填,打破了宽缝老混凝土面必须进行人工凿毛处理和二期混凝土只能在低温季节浇筑的常规,合理解决了工期和质量的矛盾,加快了施工进度,确保了关键工期。

Wangkuai reservoir reinforcement project basis on the progress requirements, in the slit width of the spillway for the first time by 302 screen Lake licensing deal with the interface of concrete and concrete-mixing UEA expanders new technology. Ahead of a slit width of the two concrete backfilling, and breaking the old concrete surface slit width which is must be manually processing and cutting hair in the only two concrete pouring conventional low-temperature season. The contradictions between time and quality is solved. The construction progress is speed up, meanwhile the key time is ensured. Speed up te construction progress, Time to ensure that the key.
