随着交通建设的发展,公路设计中桥涵结构物占公路里程的比例逐步增加,对结构物的现场养生越来越规范化标准化,在大风高温地区由于自然环境恶略采用传统养生方式很难保证养生的质量及效果,造成结构物的耐久性不能达到设计的使用年限及要求,过早出现混凝土表皮脱落、麻面等质量问题,本工法可以有效解决大风高温地区现场混凝土养生的难题,有效提高混凝土的早期强度及耐久性,节约养生成本,操作简单实用,可以满足各种薄壁式墩台的现场养生要求。
With the development of traffic construction, the proportions of bridge and culvert structures in highway design gradually increase and the on-site regimen of structures is standardized and standardized more and more. In the high-windy areas, it is difficult to ensure the health preservation due to the adverse natural environment The quality and effect of the structure, resulting in the durability of the structure can not reach the design of the service life and requirements, premature emergence of concrete skin off, such as the quality of pockmarked, the method can effectively solve the problem of high-temperature windy area concrete health problems, and effectively improve the concrete The early strength and durability, saving health costs, simple and practical operation, to meet a variety of thin-walled piers on-site health requirements.
