西安XX大学本科毕业设计（论文）摘要本设计包括给水系统、污水系统两部分。给水工程为城市的一个重要基础设施，必须保证以足够的水量、合格的水质、充裕的水压供应生活用水、生产用水和其它用水。给水系统设计步骤：根据最高日用水量变化曲线计算水塔和清水池调节容积；进行管网定线，计算管段设计流量、管径和水头损失；最高时环状网管网平差计算；确定水塔高度和水泵扬程；分别进行不利管段事故时、消防时、最大转输时校核。然后根据上述计算，算出最高时各节点水压，绘制等水压线。排水工程在环境保护、保障人民健康和经济上有重要意义。排水系统根据对生活污水、工业废水和雨水的不同排除方式所形成的排水系统称作排水体制。排水体制一般可分为两种类型：合流制和分流制。本设计根据当地地形特点和经济状况，采用雨水、污水分流制。设计步骤：分别对污水和雨水系统进行管网定线；然后根据各自汇水面积计算管段流量；确定管径、坡度及埋深，最后根据计算结果绘制污水管道纵断面图。关键词：设计流量，给水系统，排水系统，雨水系统，管网定线西安XX大学本科毕业设计（论文）ABSTRACTThedesignincludeswatersupplysystems,sewerageintwoparts.Watersupplyprojectforurban,industrialasanimportantinfrastructure,theneedtoensureasufficientquantityofqualifiedwater,amplesupplyofwaterpressure,waterandotherproductionwater.Watersystemdesignsteps,Accordingtothemaximumdailywaterdemandcurvecalculationofthetowersandadjustvolume-pool.Networkforalignmentofthecalculationofthedesignflow,diameterandheadloss.RingNetworkatthehighestnetadjustmentcalculation;Identifyhightowersandpumpslift.Wereadversepossessionoftheaccident,fire,thebiggesttransferwhenchecking.ThenBasedontheabovecalculations,calculatedatthemaximumnodepressure,drawingwaterpressureline.Drainageprojectsinenvironmentalprotection,protectionofthepeople'shealthandeconomicimportance.Accordingtothedrainagesystemofdomesticsewage,industrialwastewaterandstormwaterdifferentexclusionasaresultofthedrainagesystemknownasthedrainagesystem.Drainagesystemcanbedividedintotwogeneraltypes:Combinedandtriagesystem.Accordingtothedesigncharacteristicsofthelocalterrainandthestateoftheeconomy,useofrainwaterandsewagetriagesystem.Designsteps:Respectivelyofsewageandstormwatersystemsnetworkalignment.Thenaccordingtotheirrespectivecatchmentareaofpipeflow;Determineddiameter,depthandslope,Finally,accordingtotheresultssectionofmapdrawingsewers.KEYWORDS:Designflow，Water-supplySystem,Drainagesystem,Stormwatersystem，Pipenetworkfixed-line西安XX大学本科毕业设计（论文）目录前言.....................................................................................................................................1第1章设计任务.................................................................................................................21.1广西省兴业县某地区状况资料.....................................................................................21.1.1自然状况.....................................................................................................................21.1.2工程现状资料.............................................................................................................21.1.3远期规划.....................................................................................................................31.2给水部分........................................................................................................................31.2.1兴业县某地区最大设计供水量计算资料..................................................................31.2.2绘制日用水量变化曲线及计算水塔、清水池容积.................................................31.2.3环状管网布置.............................................................................................................41.2.4管段流量、管径和水头损失计算及环状网计算.....................................................51.2.5确定水塔高度、水泵扬程（房屋按4层计算）.....................................................51.2.6异常情况下的校核.....................................................................................................51.2.7给水系统设计要求.....................................................................................................51.3排水管网部分................................................................................................................51.3.1排水管网设计内容......................................................................................................51.3.2排水管网设计要求.....................................................................................................7第2章给水管网设计计算...............................................................................................82.1设计用水量的组成.........................................................................................................82.2设计用水量的计算.........................................................................................................82.2.1最高日用水量计算......................................................................................................82.2.3最高日最高时用水量..................................................................................................92.2.4清水池和水塔有效容积的计算................................................................................102.3管网水力计算...............................................................................................................122.3.1.水方案的确定............................................................................................................122.3.2比流量计算................................................................................................................142.3.3沿线流量计算............................................................................................................16西安XX大学本科毕业设计（论文）2.3.4节点流量计算....................................................................
