本论文主要对超高层建筑的供水方式选择、排水系统势能消除和雨水系统设计等方面进行了探讨。结论显示,在办公楼类超高层建筑中宜采用分区变频供水,而酒店类超高层建筑建议采用屋顶水箱重力供水;同时,可采用立管上隔一定距离设置“乙”字弯和设置通气立管与大气相通等措施以消除排水系统势能。论文最后从雨水设计重现期、雨水管材和雨篷设计等方面对雨水系统设计了进行了初步分析。 This thesis mainly discusses the choice of water supply mode, the elimination of potential energy of drainage system and the design of rainwater system in super high-rise buildings. The conclusions show that in the office building super high-rise building should adopt the district frequency conversion water supply, and hotel super tall building proposed roof water tank gravity water supply; at the same time, can be used riser pipe set a distance from the “B” bend and settings Ventilation risers and atmospheric communication and other measures to eliminate the drainage system potential. Finally, the thesis analyzes the design of stormwater system from the aspects of stormwater design, rainwater pipe and awning design.
