“WwwWⅩⅩⅩⅩ”世界最大跨度WwwWⅩⅩⅩⅩ缆吊系统“上岗”

  中新WwwWⅩⅩⅩⅩ社贵州安龙11月4日电 (WwwWⅩⅩⅩⅩ记者 瞿宏伦)随着一段长15.4米、宽30.5米、净高8米、重约215吨的钢桁梁通过世界最大跨度的缆吊系统精准吊装至花江峡谷上空,贵州六枝至安龙高速公路花江峡谷大桥4日完成首件钢桁梁吊装,标志着世界最大跨度缆吊系统“上岗”。

  花江峡谷大桥(以下简称:大桥)是贵州省桥旅融合示范性项目工程,大桥主桥跨径1420米,桥面至水面高度625米。建成后,大桥主桥跨径居山区桥梁跨径世界第一,大桥也将超越杭瑞高速北盘江大桥565米的垂直高度,成为新的世界第一高桥。

  大桥主桥共有93个钢桁梁节段,梁段总重量达2.1万余吨,标准节段总重约215吨。此次吊装节段为大桥跨中AL1(安龙岸)段。

  项目经理吴朝明说:“大桥横跨北盘江,山高谷深,不具备垂直运输条件。为了完成‘世界第一WwwWⅩⅩⅩⅩ跨’的钢桁梁吊装作业,我们配备了目前世界最大跨度的缆吊系统。”

  吴朝明介绍,大桥缆索缆塔最大高度为262米,整个缆吊系统由运输系统、吊装系统、智慧监控系统等主要系统组成。

  记者了解到,大桥钢桁梁吊装采用了自主研发的智慧缆索吊装系统,在主塔下方设置了智慧控制中心,全桥设置了30余套高清摄像头及各类监测传感器。

  “除了常规的功能配置外,大桥智慧缆吊系统增加了视频监控点、北斗精准定位、缆索吊全自动控制系统(一键吊装)等功能,有效保证了整个吊装过程安全可控。”吴朝明说。(完)
