摘要
根据水闸混凝土冬季施工的相关技术要求,综合考虑北运河流域的气象条件和现场作业条件,本着确保工程质量的原则,选用了综合法进行北运河榆林庄闸墩混凝土的冬季施工,综合法主要特点为:进行专门的冬季施工混凝土配合比设计,在混凝土拌和物中掺加适量的防冻剂;对混凝土拌合物出罐温度进行控制;对浇筑过程中及成型后混凝土采用暖棚法养护。
According to the requirementsof the relevant technology of sluice concrete construction in winter, consideringthe basin meteorological conditions and field operating conditions of North Grand canal, and in line with the principle of ensuring engineering quality, the comprehensive method was used to process the pier concrete, and specialize the mix design of concrete in winter construction, concrete mixture was mixed with the right amount of antifreeze agent and the temperature was controlled when the concrete mixture is out, and the greenhouse method was used to maintain the concrete during the casting process.
