在34层高度的试验塔上,分别采用定流量排水和瞬间流排水,得出不同排水方式下各排水系统相应的排水能力,并与规范值比较。结果表明:各系统排水能力瞬间流测试值与我国2009年版《建筑给水排水设计规范》(GB 50015—2003)的规范值变化趋势接近,排水能力由高到低排序为:规范值﹥瞬间流测试值﹥定流量测试值,且排水系统的高层排水区域与中低层排水区域的排水能力衰减率不同。
On the 34-storey test tower, the corresponding drainage capacity of each drainage system under different drainage methods was obtained by constant flow drainage and instantaneous flow drainage, respectively, and compared with the standard values. The results show that the instantaneous flow test value of drainage system of each system is close to the change trend of the normative value of “Design Guideline for Building Water Supply and Drainage” (GB 50015-2003) in 2009, and the ranking of drainage capacity from high to low is: Normal value> Instantaneous flow test Value> constant flow test value, and the drainage system in the drainage area and the drainage area of the lower drainage rate decay rate is different.
