摘 要

本设计建筑为位于江苏南京的锦绣联合商务大厦，总建筑面积15960平方米，地下建筑面积1300平方米，地面总高度为63.75米，地下一层，地面以上15层，其中有群楼6层为宾馆，主楼15层为办公、会议等纯办公用房。给排水工程设计包括了室内生活给水系统设计，室内排水系统设计，室内外消防给水系统设计，热水系统以及雨水系统设计。

生活给水系统分为两个区：地下室至四层为低区，采用市政给水管网直接供水；五层至十五层为高区，利用变频泵系统供水。消防给水系统分为消火栓给水系统和自动喷淋灭火系统，本建筑为一类公共建筑，而其建筑高度≥50m，按高层民用建筑防火设计规范》规定，室内消火栓用水量和室外消火栓用水量分别取30L/s和40L/s，自动喷淋系统计算用水量为16L/s，自动喷淋系统在屋顶设增压设备，火灾初期10min消防用水量由屋顶消防水箱供给，消防水箱的水源由消防泵从消防水池抽取；10min后启动消防水泵，从消防水池抽水。排水系统采用污废合流制，排水系统采用特殊的双立管排水系统，通气冒高出屋顶2.00m，底层单排。热水系统采用集中热水供应系统，采用上行下给立管循环，热水只供六层裙楼宾馆洗浴用水。给水系统采用PP-R给水管材，消火栓给水系统和自动喷淋灭火系统采用铸铁管，排水系统立管采用PPI螺旋排水管，各层排水支管采用普通的UPVC排水管。在地下层设贮水池和加压泵房，地下室另设集水坑，集水坑中设潜污泵，保证污水及时排出。

Abstract

The architectural design is located in Nanjing, Jiangsu jinxiu joint business building, 1596 square meters with a total construction area, underground construction area of 1300 square meters, ground with a total height of 63.75 metres, underground layer, 15 floors above ground, which has buildings 6 layers for the hotel, the main building 15 storey office. Conference and other pure office with real. Water supply and drainage engineering design includes indoor water supply system design, indoor drainage system design, indoor and outdoor fire water supply system design, hot water system and rainwater system design.

Life water supply system is divided into two areas: basement to four layer for low area, the direct supply of municipal water supply pipe network; five to 15 storeys for the area using variable speed pump water supply system. Fire water supply system for fire hydrant system and automatic sprinkler fire extinguishing system, the building is a public building, and the building height is equal to or larger than 50m, in accordance with the provisions of the code for fire protection design of tall buildings, indoor fire hydrant water and outdoor fire hydrant water were taken 30L / S and 40L / s, automatic sprinkler system calculating water consumption 16L/s, automatic sprinkler system on the roof design pressurization equipment, fire in the first 10min fire water from the roof fire water supply, fire water tank of water by the fire pump from the fire pool extraction; 10 min after start fire pump, fire protection water pumped from the. The drainage system uses sewage and waste combined system. The drainage system adopts special double drainage system, and the ventilation runs out of the roof 2.00m, the bottom is single row.. Hot water system adopts centralized hot water supply system, the uplink to the vertical circular tube, hot water for six storey podium hotel bath water. PP-R water supply pipe is used in water supply system, fire hydrant system and automatic sprinkler fire extinguishing system using iron pipe, vertical drainage pipe is made by PPI spiral drainage, drainage branch pipe of each layer by ordinary UPVC drainage tube. In the underground layer design storage tank and pump pressure, underground chamber and the other set puddle, set a puddle in the submersible sewage pump to ensure timely discharge of sewage.
