10、，以及为了满足工期的要求，考虑到多个作业面的交叉作业的现场要求，根据建筑电气工程施工质量验收规范（GB503032002）、施工现场临时用电安全技术规程（JGJ46-2005）等规定，按照甲方提供的供电电源位置和供电功率，合理配置机械设备及电力设施。编制说明：本临时用水用电方案用于指导施工现场临建布置，便于现场加强对现场用水用电进行安全技术管理提供理论依据。2、工程概况美每家研发中心及标准厂房F号楼工程，工程占地面积16475平方米，规划总建筑面积为67007.37M2。设计单位为机械工业第六设计研究院。3、现场用水、用电设计 针对本工程的特点，为了确保现场施工的需要，合理组织生产提供良好的前
11、提条件，根据现场实际情况和现行的施工用水用电管理规范，进行现场施工用水用电的设计。3.1、临时用水设计临时用水包括施工用水q1、施工机械用水q2、施工现场生活用水q3、生活区用水q4、消防用水q5。各用水量计算如下:1)施工现场用水量按下式计算：q1=k1q1施工用水量k1用水系数取1.15Q1工程量N1施工用水定额t1有效作业日T每天工作班数K2用水均衡系数取1.5四个瓦工班8小时内的砌筑量(每班以砌砖20m3计)混凝土养护8小时内用水(自然养护以20m3计)N1以每立方米砂浆搅拌耗水量取600L/m3计，每立方米混凝土养护耗水量以300 L/m3计。q1=1.15(33.2600+4202
12、00+300300)1.5/(83600)=6.69L/ S2 )施工机械用水量:q2=k1q2施工机械用水量k1用水系数取1.15Q2同一种机械台数N2施工机械台班用水定额k3用水不均衡系数取2.00根据现场施工机械计划初步估计,q2=2.5 L/ S3)施工现场生活用水量q3=q3施工现场生活用水量P1施工现场高峰昼夜人数(人)，取400人N3施工现场生活用水定额(一般为2060L/人班),取40L/人班K4施工现场生活用水不均衡系数,取1.5t每天工作班数q3=400*40*1.5/1*8*3600=0.83L/ S由于本工程的主要生活区不在现场,故用水量可以不计。4)生活区生活用水量根
13、据现场实际情况,项目一期工程现场除安排办公室及部分临时生活设施外,主要生活区及工人生活区另设他处,故用水量不考虑。5)消防用水量q5根据规定,现场面积在5公顷以内者同时发生火警2次,消防用水定额按1015L/S考虑,据现场占地面积, q5暂按15L/S考虑.6)总用水量(Q)计算q1+q2+q3+q4q5,且工程面积小于5公顷故Q= q5=15L/S7)供水管直径d=管网中水流速度,取=2.5d=0.087m故选用供水管为100,现场总用水量约为60t/h。甲方提供DN100管径的给水管，满足需要。施工供水采用50的PVC管按照总平面布置图沿着基坑布置，每50m留置一个阀门。3.2、临时用电设
14、计主要机械设备配置如下：序号机械或设备名称型号规格数量额定功率（KW）小计（KW）1塔吊H3/36B1701402钢筋切断机GQ40-247.5303钢筋弯曲机GJB4043124钢筋调直机43125电渣压力焊HD-5004套3126闪光对焊机21002007插入振捣器ZN60101.1118交流焊机BX3-300424969手提电锯MJ50101.11110圆盘锯MJ105441611砂浆搅拌机HJ-200631812施工井架SS1606116613套丝机441614潜水泵832415混凝土输送泵HBT602110220合计884根据机械表，本工程用电负荷可计算如下： P=1.05（k1P1/cos+k2p2+k3p3）其中：P1为电动机总功率 p2为电焊设备总容量 p3照明总功率 k1=0.5，k2=0.6，k3=0.8，cos=0.7最大用电量出现在主体施工阶段后期，砌体插入阶段。P1= k1P1
