DN100铸铁伸顶通气系统排水能力研究

Drainage Capacity of DN100 Cast Iron Pipe in Extended Ventilation Drainage System

在122.9 m高的超高层住宅性能足尺试验塔内,采用DN100铸铁管为排水立管,分别考察在采用定流量法排水和瞬间流量法排水时,超高层(33层)和小高层(15层)伸顶通气排水系统的排水能力。结果表明,两种排水方式下小高层伸顶通气排水系统的排水能力均优于超高层。

In a full scale test of a super high-rise building with a height of 122.9 m, a cast iron pipe with a diameter of 100 mm was used as the vertical pipe in the drainage system, with the purpose of determining its drainage capacity in cases when wastewater was drained from a super high-rise building and a low-rise building, using the constant flow and the instantaneous flow methods separately. The results indicated that the drainage capacity in the low-rise building was better than that in the super high- rise building, when implemented in both constant flow and instantaneous flow methods.
