压力流虹吸式屋面雨水排水系统的设计与应用探讨

Discussion on Design and Application of Siphon Roof Rainwater Drainage System

在分析压力流虹吸式屋面雨水排水系统工作原理的基础上,对该排水方式与传统重力流雨水排水方式进行了比较,讨论了压力流虹吸式屋面雨水排水系统的特点和优势,并对压力流虹吸式屋面雨水排水系统的设计与应用中的几个问题进行了探讨和分析。压力流虹吸式屋面雨水排水系统虽然是解决大面积、大跨度的工业厂房与公共建筑物的屋面雨水排水问题最有效的方式之一,但在高层建筑中应审慎采用。

Based on analysis of working principle of siphon roof rainwater drainage system, the si- phon drainage system is compared with the gravity rainwater drainage system. The characteristics and advantages of siphon roof rainwater drainage system are discussed. Some problems in design and application of this system are explored. It is concluded that although the siphon roof rainwater drainage system is one of the effective ways to solve the problems of roof rainwater drainage of industrial and public buildings with large area and large span, it should be prudently used for high-rise buildings.
