预制等切面悬链线钢筋混凝土箱拱施工技术研究

RESEARCH ON PREFABRICATION TECHNOLOGY OF REINFORCED CONCRETE BOX ARCH WITH FRACTURE

分析了当前拱桥的施工技术,针对等切面悬链线钢筋混凝土箱拱进行技术改进,提出了预制等切面悬链线钢筋混凝土箱拱施工技术,采用专门的预制场地,施工方便,不影响其它工序的进度,达到节约时间,提高效率,降低施工费用的目的。通过平面作业,减少了浇筑混凝土等工序的高空作业,降低安全事故发生概率。

This paper analyzes the current construction technology of arch bridge, for the innovation of precast reinforced concrete box arch section catenary, proposes the prefabricated construction technol- ogy of reinforced concrete box arch section catenary, prefabricated site, special construction is convenient, does not affect the progress of other processes, save time, improve efficiency, reduce the construction cost. Through the plane operation, reducing the pouring of concrete and other processes of high - altitude operations, and the probability of safety accidents is reduced.
