摘要
为适应混凝土浇筑能力和减小施工期温度应力,于闸墩中间设置预留宽缝。施工期间,根据工程进度要求,通过掺加UEA型混凝土膨胀剂,提前进行了宽缝二期混凝土的回填,打破了宽缝混凝土只能在低温季节浇筑的常规。
Double joint is set up in the middle of pier in order to adapt to the ability of pouting of concrete. During the period of construction, according to the demand of project process, second-stage concrete of double joint is backfiUed ahead of time by way of mixing expanding agent of UEA, it breaking the normal procedure of construct of concrete of double joint.
