伟鹏苑5号楼给排水工程设计

摘要本项目属于高层建筑，总高达到34层，主要以商业功能作为设计目标，首层规划成大型购物中心，其余楼层从四层到三十四层全部设计成住宅单元，这样做的目的是为了满足居民的多种生活需求，经过消防安全评估之后，这个项目被定为中危险级I级，并且严格执行当前消防技术规范中的相关要求。本次设计的研究内容涵盖该建筑的给水系统、消火栓系统及自动喷淋灭火系统的规划设计。给水系统：该建筑为为高层民用建筑，该给水系统采用分区供水方式形式，根据楼层高度特征来划分，一层到三层被划入低区范围，直接依靠市政管网供水，四层到十六层归为中区，十七层到三十四层则属于高区，中区和高区均采取无水箱变频泵的方式满足供水需求。排水系统：综合考虑建筑特征、污水处理规模以及进水水质等多种因素之后，本项目决定采用污废合流管道系统作为排水设施的设计方案。消火栓给水系统：竖直供水无需分区，由地下消防水泵与屋面水箱向消火栓系统供水。自动喷淋系统：设计需根据相关规范确定系统参数，包括喷水强度、喷头间距等关键指标，同时需进行管网水力平衡分析和流体流动模拟计算。关键词：给水系统：排水系统；消火栓给水系统：自动喷淋系统ABSRTACTThis project is a high-rise building with a total height of 34 floors,mainly designedwith commercial functions as the design goal.The first floor is planned as a large shoppingcenter,and the remaining floors from the fourth floor to the 34th floor are all designed asresidential units.The purpose of this is to meet the various living needs of residents.Afterfire safety assessment,this project has been classified as medium hazard level I and strictlycomplies with the relevant requirements of current fire safety technical specifications.The scope of this design is:research on the design of water supply,fire hydrants,andautomatic sprinkler systems for this buildingWater supply system:This building belongs to a super high-rise structure,and its watersupply system design adopts a zoning water supply method.It is divided according to theheight characteristics of each floor.The first to third floors are classified as low zones anddirectly rely on the municipal pipeline network for water supply.The fourth to sixteenthfloors are classified as the central zone,and the seventeenth to thirty fourth floors areclassified as the high zone.Both the central and high zones use variable frequency pumpswithout water tanks to meet water supply needs.Drainage system:After considering various factors such as building characteristics,sewage treatment scale,and inlet water quality,this project has decided to adopt a sewageand waste mixed pipeline system as the design scheme for drainage facilities.Fire hydrant water supply system:Vertical water supply does not require zoning,and issupplied to the fire hydrant network by underground fire pumps and roof water tanksAutomatic sprinkler system:Determine the design parameters of the automaticsprinkler fire extinguishing system based on industry standards,including spray intensityand distance between nozzles,and carry out hydraulic balance analysis and fluid dynamicssimulation calculation of the pipeline network.Key words:Water supply system;Drainage system;Hydrant water supply system;Automatic sprinkler syste目录1引言…1.1工程概况.2设计依据。2.1建筑设计资料22主要参考的设计标准和设计手册3设计说明…3.1给水系统3.1.1竖向分区.23.1.2方案的选择….23.2排水系统33.2.1方案的选择33.3雨水系统43.3.1方案的选择.43.4消火栓系统53.5喷水灭火系统.53.5.1方案的选择.64设计计算….74.1给水系统.74.1.1总水量的计算.….74.1.2生活水池的计算.84.1.3各区水力计算84.1.4生活水泵的选型…124.2排水系统..134.2.1住宅污水管…134.2.2通气管.214.2.3排污泵及集水井的计算214.2.4化粪池的选用.224.3消火栓系统计算..234.3.1消火栓的保护半径234.3.2栓口压力计算.244.3.3管网计算244.3.4消防水泵的选择.274.3.5水泵结合器的设置.274.3.6消防贮水池容积计算274.3.7高位水箱的容积计算.…284.3.8水箱高度校核及增压稳压设备284.3.9消火栓的选型.294
