跨高速公路直线段高墩托架施工关键技术研究
|
摘要
在跨高速公路施工中,直线段的高墩托架一直是施工的难题,其施工质量影响着跨高速公路整体的合龙,因此实施直线段高墩托架的技术,对于整个工程都有着非常重要的意义。以跨龙丽温高速特大桥连续梁直线段的施工为例,通过分析其直线段托架的设计和安装设计,了解到其目前遇到的施工难题,并以此提出相应的解决措施,为同类项目的施工提供参考性的建议。
In the process of cross-expressway construction,the high-pier bracket in straight section has been a difficult problem for construction. The construction quality affects the overall closure of the expressway. Therefore,the technique of straight-section high pier bracket is adopted.For the whole project has a very important meaning. Taking the construction of straight section of continuous beam of Longliwen Super-large Bridge as an example,through the analysis of the design and installation design of the straight-line bracket,the current construction problems encountered are discussed and the corresponding solutions are proposed. The construction of similar projects provide reference suggestions.
