摘　　要：在122.9 m高的试验塔上,采用定流量法排水,对不同的特殊双立管系统进行了比对试验研究,探究各系统的排水能力及其影响因素。结果表明,定流量法排水时不同特殊双立管系统的排水能力为结合通气管采用旋流配件的特殊双立管系统>结合通气管与旋流器结合(四通旋流器)的特殊双立管系统>采用H管件(斜三通)连接的特殊双立管系统;结合通气管管径越大,系统排水能力越大。The constant flow method was used to drain water from a 34-floor tower. A comparative experiment including four different special double stack drainage systems was carried out to investigate the drainage capacity and the influencing factors in each system. The results showed that the drainage capacity of the special double stack drainage systems in descending order was ： the system using cyclone fittings to connect the yoke vent, the system using cross fitting to connect the yoke vent, and the system using slope tee to connect the yoke vent to the soil stack. Moreover, the yoke vent with larger pipe diameters showed greater drainage capacity.
