Construction Technology of Stainless Steel Siphon Rainwater System in High and Large Space of Airport

以杭州萧山国际机场T4航站楼钢结构屋面虹吸雨水系统为例,介绍了超大型国际机场航站楼钢结构屋面虹吸雨水系统的设计与施工方法,探讨总结了一些需要注意的问题和解决方案。结合BIM模型技术,采用钢结构与虹吸雨水管交叉施工整体提升技术,在保证结构安全性的同时,降低了施工难度和成本。

Taking the siphon rainwater system on the steel roof of terminal T4 of Hangzhou Xiaoshan International Airport as an example,this paper introduces the design and construction methods of siphon rainwater system on the steel roof of terminal T4 of super large international airport,discusses and summarizes some problems needing attention and solutions. Combined with BIM model,cross construction and integral lifting technology of steel structure and siphon rainwater pipe are adopted to ensure safety of structure and reduce construction difficulty and cost.
