探析建筑给排水施工中的虹吸式雨水排水技术

The Siphon Rainwater Drainage Technology in Building Water Supply and Drainage Construction is Discussed

雨水排水施工是建筑给排水工程中一个重要施工项目,其质量直接关系到整个给排水工程质量,为此提出探析建筑给排水施工中的虹吸式雨水排水技术研究。根据实际情况完成对天沟的设计与修建,以及选择虹吸式排水管料,对虹吸式雨水斗、连接管、无坡度雨水悬吊管、雨水立管、埋地管、排出管安装,在排水系统布置溢流口,以此完成虹吸式雨水排水技术设计。实例分析结果表明,虹吸式雨水排水施工后建筑积水量低于最大限值,排水管流速高于最小允许限值,符合规范要求,设计技术具有良好的雨水排水效果,在建筑给配水施工中具有良好的应用前景。

Rainwater drainage construction is an important construction project in building water supply and drainage engineering,and its quality is directly related to the quality of the whole water supply and drainage engineering.Therefore,the research on siphon rainwater drainage technology in building water supply and drainage construction is put forward.According to the actual situation,complete the design and construction of the gutter,select siphon drainage pipe materials,install siphon rainwater hopper,connecting pipe,non-slope rainwater suspension pipe,rainwater riser,buried pipe and discharge pipe,and arrange overflow ports in the drainage system,so as to complete the siphon rainwater drainage technology design.The result of case analysis shows that the building water volume is lower than the maximum limit value and the flow rate of the drain pipe is higher than the minimum allowable limit value.The design technology has good drainage effect and has a good application prospect in the construction of building water supply and distribution.
