虹吸式屋面排放系统技术原理及使用特性——以湖北大学综合体育馆为例

Technical principle and use characteristic of siphon-type roof drainage system:taking Gymnasium of Hubei University for example

以湖北大学综合体育馆屋面雨水系统的安装为例,介绍了虹吸式雨水系统的技术原理和使用特性.雨水立管在满流情况下,水柱的自由落体对雨水系统的悬吊管、雨水斗产生抽吸力,使常规靠重力流的雨水变成动力流雨水,从而加快雨水的排放.雨水管所采用的高密度聚乙烯管是一种新型管材.雨水系统动力排放技术的应用使复杂、庞大的雨水管道系统简单化,大幅度地降低了建设成本.

Taking the installation of the siphon drainage system of the gymnasium roof of Hubei University for example, the technical principle and the use characteristic of the siphon-type drainage systems are introduced. Under the circumstances which the standpipe is in full-flow, the free-fall flow of water column generates a suction to the hanging pipe and the rainwa- ter head of the storm-water system, then the regular flow of rainwater by gravitational force is turned into a dynamic flow, thus speeding up the drainage of rainwater. The high-density polyethylene pipe is a new type of tubing. The application of the rainwater drainage system makes the complex and huge storm-water pipeline system simplistic, and the building costs are significantly reduced.
