互补湿通气在高层建筑排水系统中的应用

THE APPLICATION OF COMPLEMENTARY WET VENT IN DRAINAGE SYSTEM OF HIGHRISE BUILDINGS

阐述了高层建筑排水系统的特点、排水体制，着重分析了高层住宅、高层旅馆的排水系统。研究结果表明，住宅和旅馆类高层建筑２０层及２０层以下时宜采用分流制，在排水主管管径为１００ｍｍ时可以不采用三管制而采用互补湿通气排水系统，这在技术上是可行的。

This paper presents the proporties of drainage system and the form of drainagesystem and analyses the drainage system of highrise residential and hotel buildings. The results of re-search show that it is suitable to adopt separate systeni when highrise residential and hotel buildingsare not more than twenty floors. It is feasible and economic to adopt the complementary wet ventdrainage system rather than the three-pipe system when the diameter of vertical drain is 100 mm.
