摘要
针对2022卡塔尔世界杯主场馆卢赛尔体育场体量大、结构异形、结构模块质量大、精度要求高的特点,采取全站仪和3D扫描仪相配合的测量方案。介绍了单构件精度检查和吊装单元精度检查。现场在保证精度的前提下,通过合理使用3D扫描仪对单根构件、单片桁架、单个吊装模块、合龙段模块和就位处开档进行扫描,在正式吊装之前进行虚拟合龙吊装。吊装和合龙模拟对提前发现现场吊装问题起到重要作用,极大提高了拼装和安装工效。
According to the characteristics of the large size,special shaped structure,heavy weight of structural module and high precision requirement of the main stadium of Qatar World Cup in 2022,the cooperation measurement scheme of the total station and 3D scanner is adopted.The accuracy inspection of single component and the precision inspection of hoisting unit are introduced.On the premise of ensuring the accuracy,the site scan is done for the single member,single truss,single lifting module,closure section module and the open at the position by using 3D scanner reasonably,and virtual closure hoisting is analyzed before formal hoisting.The hoisting and closure simulation play an important role in the early detection of the hoisting problems on site,which greatly improves the assembly and installation efficiency.
