摘要
钻孔灌注桩水下混凝土的浇筑,由于其成桩的特殊性,无法按常规对其进行振捣、密实。自密实混凝土的应用,恰好解决了这一问题,但自密实混凝土的配比、施工等都与普通混凝土有所不同,故施工人员应周密计划、谨慎操作,控制好相关指标,确保工程质量。
There is no conventional vibrating intensifying for the pouring of underwater cement piling. The self intensi- fying cement is proper for this problem, whose proposition and application are different from the conventional cement, thus requiring careful planning and operation, relevant parameters control for the optimum project quality.
