新疆某碾压混凝土坝施工质量控制

新疆某碾压混凝土重力坝坝址所处地区冬季长且寒冷,春、秋二季短,夏季气温高且干燥少雨,多年平均气温2.7℃,年温差极大且蒸发强盛,对碾压混凝土施工非常不利。为了保证碾压混凝土坝的施工质量,必须对混凝土的施工全过程进行严格控制。通过对原材料、拌和系统、施工仓面的全面有效控制,最终混凝土施工质量全部达到设计及施工规范标准。

Construction Quality Control of a RCC Dam in Xinjiang

A RCC gravity dam locates at the region in Xinjiang where the winter is long and cold,the spring and autumn is short,the summer is hot and dry and the annual average temperature is 2.7 ℃,the great temperature difference and high evaporation are adverse to the dam construction.In order to ensure the construction quality,the raw materials,mixing systems and concrete placement surface are strictly controlled in whole construction.The quality of concrete construction meets the requirements of design and specifications.
