为保证安全度汛,察汗乌苏水电站溢洪洞工程需进行冬期施工。结合工程实际,介绍了溢洪洞冬期施工时为保证混凝土质量采取的一系列措施,如调整混凝土配合比、增大水泥用量,提高建筑材料温度,对混凝土拌合设备、泵送设备进行保温等。并运用预算定额、成本加酬金两种方法编制冬期混凝土施工增加费。结果表明,在节省成本的同时,确保了工期和质量,取得了良好的社会效益和经济效益。
In order to ensure the safety flood season, Chahanwusu hydropower station flood spillway project needs winter construction. According to engineering practice, a series of measures to ensure the quality of concrete during winter construction of spillway tunnel are introduced, such as adjusting the mix proportion of concrete, increasing the amount of cement, raising the temperature of building materials, keeping the temperature of concrete mixing equipment and pumping equipment . And use the fixed budget, the cost plus remuneration two methods of winter construction of concrete construction costs. The results show that, while saving costs, to ensure the duration and quality, and achieved good social and economic benefits.
