Description

平行钢丝束股的水平收束和水平放束方法 技术领域
本发明涉及专门适用于搬运或安装供贮存和重复放出、 重新贮存为特殊目的， 提供各种长度材料的薄的或细丝状材料的方法领域， 具体为一种平行钢丝束股的 水平收束和水平放束方法。 背景技术
主缆单元索股是悬索桥的主要承重构件， 单元索股一般由 5mm系列的高强度 镀锌钢丝集束而成， 以往单元索股的规格一般为 61丝、 91丝和 127丝， 目前超长 大规格主缆单元索股规格达到 (D5mm X 5000m X 169丝， 单根单元索股的重量达到 120吨， 单元索股截面一般为正六边形， 一些特殊索股也可以是矩形或其他形状， 单元索股每隔 1.5m〜2m用复合包带包扎。传统上， 国内外在主缆单元索股的收卷 工艺上均采用大直径钢盘收卷水平排线的技术， 这种技术简称为成盘工艺。 成盘 工艺的特点之一是从索股的制作、 运输和放索都离不开大直径钢盘。 在成盘索股 运往大桥工地的过程中， 索股由于自重原因， 索股会产生椭圆形堕坠， 如图 1 所 示， 由于索股 10产生椭圆形堕坠从而使得索股 10卷绕松弛， 钢盘旋转时索股之 间会产生摩擦； 索股随钢盘不断地旋转过程中， 这种堕坠会产生所谓的 "呼啦圈" 效应， 从而打乱卷绕束股应有的排列次序， 使得放束时束股牵出困难； 放索中的 牵引拽拉使卷绕松弛的束股忽紧忽松， 钢丝束股间的摩擦更会加剧， 使包带擦伤 直至断裂， 造成束股钢丝松散。 补救的方法是在现场不断地对束股进行人工整形 和包扎， 对已经形成的呼啦圈要停机抽紧后再放束， 这不仅给主缆的拼装成型带 来极大不便， 更严重的是要影响工期。 放索过程中出现的 "呼啦圈"现象， 会随 着放索过程的进行而变得越来越严重， 松弛量会逐渐增大， 索股将会碰撞到地面， 直至放索施工无法正常进行。 尤其是当索股长度越长的时候， "呼啦圈"现象越严 重， 而且索股的长度越长， 补救的措施将越难进行， 甚至无法进行。 根据经验， 在索股形状保持良好的前提下， 采用成盘工艺， 一般索股长度超过 1500m， 在放 索时容易出现 "呼啦圈"现象， 严重时直接影响到现场施工进度和索股质量。 发明内容
