摘要:在综合对比分析的基础上，设计建筑给水系统、建筑排水系统、建筑消防系统（消火栓给水系统及自动喷水灭火系统）、建筑屋面雨水排水系统设计。

　　　给水系统采用分区供水，低区地下一层到七层，由市政管网直接供水；中区八到十三层，采用水泵变频供水。排水系统采用污、废水合流制，底层单独排放，排水立管设伸顶通气管，污废水在地下室顶部排除室外，并排向检查井接化粪池。消防系统分消火栓给水系统和自动喷水灭火系统，其中消火栓系统采用水泵水箱联合供水。屋面雨水排水系统采用天沟内排水。

　　　给水管采用PP-R管；热水管采用PP-R管；排水管采用UPVC管；消防系统均采用钢管。

Abstract:Based on the synthesis analysis, the water supply system, the drainage system, fire system(fire hydrant system and automatic sprinkler system) and roof drainage system for the high twenty second commerce-residence building building of military division residential designed.

　　　The water supply system is applied by vertical division block.Low district underground layer to the four layers, the municipal water supply pipe directly; The central five to 13 layer, high area 14 to twenty second floor, the water supply pump frequency conversion. The drainage system is an interflow system of sewerage and waste water. Water of the first floor drains together，the upright draining pipes are equipped with the ventilating pipes, and then the sewerage is drains to the municipal waste pipe network. The fire system includes the fire hydrant system and automatic sprinkler system. The roof drainage system is an outside drainage system. 

　　　The water supply pipes and drainage pipes are made of the PP- R pipes and the cast-iron pipes respectively, and the material of the fire fighting system is made of steel pipes.

　　　分析了高层建筑的给排水的任务和特点，并对高层建筑给排水系统的发展趋势进行了客观科学的有效推理，高层建筑给水排水工程无论是在技术深度上，还是广度上，都超过了低层建筑物的给水排水工程的范畴，并且其中有一些特点，如高层建筑给水排水设备的使用人数多，瞬时的给水量和排水流量靠的水源，以及经济合理的给水排水系统形式，妥善处理排水管道的通气问题等，只有合理的设计才能保证供水安全可靠、排水通畅和维护管理方便。
