摘　　要：武汉T3航站楼为大型交通建筑,给水排水系统设计是建筑设计的重要组成部分,本文通过分析给排水需求,科学设计生活给水系统、生活排水系统、雨水排水系统、热水系统,饮水供应、空调循环冷却水系统。创新设计包括:采用分散式或相对集中式的方式供应,保证了用水舒适性,又节约工程造价,冷却水泵房安置在冷却塔底部地下室内,简化了冷却水管路,冷却塔选用无集水盘结构,在冷却塔底部设置共用集水池,有利于冷却塔水力平衡调节,将停泵时冷却塔进水管跌落下的水储存起来,节约补水量,冷却塔风机采用变频控制,节约电能。航站楼下设置综合管廊敷设机电管线,集约用地且利于日常维护。本文对大型机场航站楼的给排水系统设计提供参考案例。Wuhan T3 terminal is a large-scale transportation building,and the water supply and drainage system design is an important part of the architectural design.Through the analysis of water supply and drainage needs,scientific design of domestic water supply system,domestic drainage system,rainwater drainage system,hot water system,drinking water supply air conditioning circulating cooling water system.Innovative designs include:adopting a decentralized or relatively centralized supply method to ensure water comfort and save engineering cost;the cooling water pump house is placed in the basement at the bottom of the cooling tower,which simplifies the cooling water pipeline;the cooling tower uses no water collecting pan.structure,set a common catch basin at the bottom of the cooling towei;which is conducive to the adjustment of the hydraulic balance of the cooling tower,store the water falling from the cooling tower inlet pipe when the pump is stopped to save the water supply;the cooling tower fan adopts frequency conversion control to save electricity;a comprehensive pipe galleiy is set downstairs to lay electrical and mechanical pipelines,which intensively uses land and facilitates daily maintenance.This article provides a reference case for the design of the water supply and drainage system of a large airport terminal.
