虹吸式雨水排水系统技术分析及建筑给排水设计应用

Technical Analysis of Siphon Rainwater Drainage System and Application of Building Water Supply and Drainage Design

随着我国经济的发展以及城市化进程的不断推进,大型公共建筑不断涌现。屋面虹吸雨水排水系统以其高效排水能力,得以在大型屋面工程建设中大量运用。虹吸雨水系统单斗排水能力远大于重力流雨水系统,且可实现悬吊筒无坡度敷设,优势较为明显。文章鉴于虹吸雨水系统特性,分析探讨其优点及在设计中虹吸雨水系统的常见问题。针对虹吸雨水排水系统满流工况动态负荷大,筒道材料选择等问题提出解决方案。

With the development of China＇s economy and the continuous progress of urbanization process, large public buildings continue to emerge. Roof siphon rainwater drainage system with its efficient drainage capacity, to large-scale roofing construction in a large number of applications. Siphon rainwater system single bucket drainage capacity is much greater than the gravity flow rainwater system, and can achieve the suspension tube without slope laying, the advantage is more obvious. In view of the characteristics of the siphon rainwater system, the paper discusses the advantages and the common problems in the design of the siphon rainwater system. Aiming at the problem of large dynamic load and selection of channel material in siphon rainwater drainage system, the solution is put forward.
