摘 要

钱隆城18号楼位于江苏南京，建筑高度93.4m，共31层。设计内容包括建筑给水系统、建筑排水系统、建筑雨水系统、建筑消防系统四个部分，要求最终主要成果有图纸目录、设计施工总说明、平面施工图、卫生间大样图、泵房大样、系统图、图例、设备材料表、设计计算书等。

生活给水系统分为三个区：一到二层为低区，采取市政水压直供，市政水压0.2

Mpa；三到十七层为中区，十八到三十一层为高区，采取无负压水泵加压供水。住宅部分每户设置单独的水表，水表设置在改成水井内。

生活排水系统：一层采取“底层单排”原则，单独排至室外污水检查井；二至三十一层采用降板式同层排水，排水立管采用双立管排水，设置专用通气管，排水立管管做伸顶通气，隔层设置检查口。雨水系统：采用2014版南京市暴雨强度公式，采用87式雨水斗，屋面收集雨水后经雨水排水立管排至地面雨水口，间接排水。

根据《建筑设计防火规范》GB 50016-2014的规定，本建筑为一类高层住宅建筑，室内消火栓用水量为20L/s；自喷危险等级为中危一级，用水量为21L/s。屋顶消防水箱为10min的消火栓及自喷用水量，水箱容积为25m³。消防水池贮存2h的消火栓用水量及1h的自喷用水量，设计容积为220m³。消火栓采用SN65型室内单栓消火栓， QZ19型直流水枪，DN65长25 m的衬胶水带。自喷系统采用湿式系统，喷头动作温度为68℃。

Qian Long Chen 18^th building Water supply and drainage engineering design

Abstract：The main content of this design is a resource county by royal garden near the building water supply and drainage engineering design, design content including architectural water supply system, drainage system, rain water system, building fire system four parts, require the final main achievements are drawing list, design and construction of the total, the plane construction drawing, toilet details, pump room details, system and the principle diagram, legend table, equipment, materials, design calculation, etc.Due to the particularity of high-rise buildings, such as the layer number of many large, highly, wide functions, complicated structure, and the restriction of the various external conditions, forcing people to seek the most economical optimization design, including the choice of the reasonable way of water supply, the optimal partition, the vertical pipe network optimization design, selection of reasonable water pump to save investment, such as saving the resources.

Water from urban pipeline network of water supply, the introduction of tube is introduced into the basement layer without negative pressure equipment system, from the negative pressure equipment for water pipes and water supply directly by the municipal pipe network household set riser pipe after pipe well through the layers of the user after a water meter door connecting the sanitary ware.The well water meter of water supply cold water pipe laying by the leveling layer.According to the building of the situation and the applied conditions of each system, drainage design is proposed to adopt double riser pipe drainage system.Discharge sewage, waste water confluence system.Above the kitchen and the bathroom on the second floor drain drop plate setting (toilet), by a drainage riser cross into the second floor ceiling drainage mains, the sewage, waste water discharge alone, the first floor into outdoor drainage after inspection Wells into the urban sewage pipe network.Fire and spray water supply scheme as follows: using a water pump, water tank fire hydrant water supply, fire water supply for the municipal tap water, after the introduction of indoor storage in underground fire pool, provided by the fire hydrant pump pressure, pump supply pressure according to the area of high pressure required to determine the most unfavorable point.According to "code for fire protection design of buildings" GB 50016-2014 the provisions of the second kind of high-rise building fire resistance rating should not be lower than the secondary, basement of high-rise building fire resistance rating should be level.Respectively according to the system design calculations, drawings and the selected main equipment.

Keywords: building water supply system design;Building drainage system design;Fire control system design.
