摘要:
强降雨下，雨水检查井内液面上升，可能导致建筑排水排出管末端处于淹没状态。基于普通结合通气双立管、防返流H管双立管和环形通气双立管三种建筑排水系统，在常规出流和淹没出流情况下对排水系统通水能力进行了研究。结果表明，淹没出流对建筑排水系统的通水能力有极大的负面影响，而环形通气条件下，淹没出流的建筑排水系统仍能达到6.0 L/s。建议工程中尽可能避免淹没出流情况的发生，如果建筑排出管出流位置较低，应尽可能在排出管位置设置通气回路。
Abstract:
Under conditions of heavy rainfall, the liquid level in the rainwater manhole rises, potentially resulting in submergence of the terminal section of the building’s drainage pipe. The drainage capacity of building drainage systems was investigated under both conventional and submerged discharge conditions, based on three configurations: the common combined double vent stack system, the anti- backflow H-shape double vent stack system, and the circular double vent stack system. Submerged outflow significantly reduced the drainage capacity of the building drainage system. Nevertheless, the circular double vent stack system could still maintain a flow rate of up to 6.0 L/s. It is recommended to avoid submerged discharge conditions to the greatest extent possible in project design. If the drainage pipe outlet of the building is located at a relatively low elevation, a ventilation system should be installed.
