1、2、1给排水安装工程
给排水安装工程包括:生活给水系统、热水系统、中水给水系统、消火栓系统、自动喷洒系统、污废水排水系统,雨水排水系统和卫生洁具安装。
1、2、1、1生活给水系统
本工程生活给水分区供给，分为低区及高区二个部分。地下三层至地上四层为低区供水系统,五层至十一层为高区供水系统。
低区给水系统水源由市政管网直接提供,由管径DN１0０热镀锌钢管双管引入,分由立管G1L－１～G1L-９、G１Ｌ-6＇及ＧL－C供低区各用水。
高区供水水源由市政管网经二路DN100引入地下三层生活水池(18Ｍ3),通过三组变频调整泵(二用一备）加压后分由立管GＬ-1~GL－5送到高区各用水点。生活水池水位及变频调速泵得启停均实行自动控制。
低区、高区给水方式均为下供上行式。给水管管材采用热镀锌钢管,丝扣或法兰连接。
1、2、1、2生活热水系统
生活热水系统分区供给与生活给水系统分区相同。生活用热水由小区热力管网提
