Suspension bridge main cable strand mark alignment erection method based on multiple reference cable strands
The invention discloses a suspension bridge main cable strand mark alignment erection method based on multiple reference cable strands. The method comprises the following specific steps: (1) selectingthe position of a reference strand; (2) determining the layer distance of the cable strands; (3) accurately calculating the blanking length of the cable strand; (4) manufacturing a standard wire; (5)manufacturing marks in a saddle factory; (6) mounting a cable saddle; (7) obtaining a cable strand length change value; (8) correcting a saddle cable strand alignment point; (9) aligning and erectingthe cable strands; and (10) carrying out multi-reference strand erection and relative elevation correction. The method mainly solves the problems that when the main cable strand is erected through anexisting sag method, under the stable weather condition, the sag needs to be measured and adjusted many times, the linear requirement can be met, the construction period is long, and the constructiondifficulty is large. By using the multi-reference cable strand erecting method provided by the invention, sag adjustment is not needed any more, influence of the climate environment is avoided, and the purposes of improving the main cable erecting quality and shortening the construction period are achieved.
本发明公开了一种基于多基准索股的悬索桥主缆索股标记对位架设方法；该方法具体步骤如下：(1)基准索股的位置选取；(2)索股层距的确定；(3)精确计算索股下料长度；(4)标准丝制造；(5)鞍座厂内制造标记；(6)索鞍安装；(7)索股长度变化值；(8)鞍座索股对位点修正；(9)索股对位架设；(10)多基准索股架设及相对标高修正；本发明主要解决目前垂度法架设主缆索股时，需要在较平稳的气候条件下，多次测量调整垂度才能满足线形要求，导致施工周期长、难度大的问题。使用本发明提出的多基准索股架设法，无需再进行垂度调整，无视气候环境的影响，达到提高主缆架设质量，节省工期的目的。
