(4)、桥架内电缆敷设Layout cable inside tray.a安装质量要求 Installation quality requirements: 电缆的最小弯曲半径应符合GB50168一92的规定，即：The minimum bending radius should conform to Norm of GB50168-92.多芯控制电缆 10D聚氯乙烯绝缘电力电缆 10D聚氯乙烯绝缘电力电线多芯 15D交联聚乙烯绝缘电力电线单芯 20D注D为电缆外径。Multi-core control cable 10DPVC insulated power cable 10DPVC insulated multi-core power cable 15DLinking PVC insulated one-core power cable 20DNote: D is outer diameter.电缆的固定要求：桥架上垂直敷设每隔2m处，水平敷设的电缆首末两端及转弯、电缆接头两端处应加以固定， Requirements for fastening cable:Fix cable every 2 meters when laying cable vertically. For horizontal layout cable, fixing it at the beginning and end, two sides of corner and joint.交流系统的单芯电缆应使固定夹具不构成闭合磁络，且按正三角形排列，每隔1m用绑带扎牢。For AC one-core cable, fixing it with special clamp not to form closed magnetic loop and arraying it in form of pure triangle. Banding tightly every 1 meter.桥架上交流三芯电力电线不宜超过2层控制电缆不宜超过三层。AC multi-core power cable should be not beyond 2 layers, and control cable no more than 3 layers.电缆的排列：高低压电力电缆、强电弱电控制电缆应按顺序分层配置，高压与低压增加隔板。Arraying order of cable: Place high and lower voltage power cable, intensive and faint control cable in layer and in sequence. Add partition between high and lower voltage power cable.b、敷设方法 Layout method: 电缆应从电缆盘上部引出，同时检查是否有套扣现象，将写好的电缆编号交专人负责贴在电缆首末端。Pulling cable from the upper direction of drum. Meanwhile, checking whether existence of cable-wring or not. Make special employee to stick prepared cable number on both ends of cable. 桥架上所有电缆全部敷设完毕，即时安装盖板，达到防护的目的。After completion of all cable layout inside tray, installing covers timely to protect.(5)、地埋电缆的敷设方法及质量要求Layout method and quality requirements for buried cable under ground:a、质量要求：Quality Requirements:电缆上表面距地坪面不小于07m。0.7m is the least distance from the upper side of cable to grade.电缆上边及下边应复以100mm的软土或沙层，并盖上红砖或混凝土板。Fill 100mm thickness soft earth or fine sand around cable up and down, and cover red brick or concrete plate. 电缆之间、电缆与其它管道、道路、建筑物等之间平行和交叉时的最小净距应符合GB5016892的表543的要求。When existing parallel or crossing between cable and cable, cable and other pipes, roads, or architectures, the minimum distance should conform to Table of 5.4.3 in GB50168-92.严禁将电缆平行敷设于管道的上方或下方。No laying cable over and under pipes in parallel过路保护管伸出道路路基两边各2m伸出排水沟0.5m。While protection pipe spreading road base, 2m should be left each side of base and 0.5m is required while spreading drainage直埋电缆在直线段每隔50100m处或电缆接头处、转弯处、进人建筑物处应设置明显的标桩。. Setting identical columns for direct buried cable at the straight line each 50-100m, at joint or swerving place and at entrance to architecture. 电缆的弯曲电缆应符合要求。Cable bending should conform to requirementb、敷设方法 Layout method:估工估料：大型的电缆敷设应做这项工作，在详细研究工程设计书后，到现场勘察线路地形并了解情况，然后制订出技术措施和安全措施，并核对设计用料是否正确，根据工程情况决定敷设方式，是采用人工敷设，还是采用机械化敷设。Estimate works quantity and necessary materials: It is required to lay large-sized cables. After studying design documents for engineering detailed, go to local field to explore lines landform and learn real environment. And then, write out technical and safety measures and check whether design materials are correct or not. According to engineering condition, decide layout method: by manpower layout or machine layout材料、工具准备：敷设电缆所需的机具设备，如卷扬机、钢丝网套、千斤顶、滑轮以及铁锹等都应需要事先备好。电缆及保护盖板等材料，最好按施工计划日期直接发运到施工现场，以节约人工费用。Prepare for materials and tools: Machines and tools needed for laying cable should be all ready in advance, such as hoist, steel-wire net, jack, rolling wheel and shovel. To economize lab our cost, we had better to deliver directly cable and cover plate to site in reference to construction plan date.对外联系工作：敷设电缆线路影响到农田、园林、公共道路、市区交通等情况应事先与农村政府、园林部门、铁路局、交通队等联系，办妥有关手续后方可施工。决定电缆中间接头的位置。当电缆线络较长有中间接头的情况下，要事先选择合适的接头位置，因中间接头故障率较电缆本体为多，因此要考虑检修问题，故不要将位置选择在道路交叉口，或与其它地下管线交叉的地方。在设计的电缆线络上开挖试探样洞，其主要目的是调查土壤及地下管线布置情况，深度1m。In order to study soil and distribution of underground pipelines, excavate exploring sample holes, 1m in depth, along the designed cable line.放样：根据设计图和土层调查情况，用石灰粉画出挖土范围Performing sample:On the basis of design drawings and soil terms, drawing out excavation region with lime powder敷设过路保护管，可采用不开挖路面的顶管方法，如果有困难应按路宽分半施工，必要时夜间施工。. When laying protective pipe through road, pushing pipe with jack is available instead of excavating ground. If it is difficult to construct, doing it on base of half of road width. If necessary, constructing at night.挖土：施工地点周围应设置警告标志，挖出的泥土应放置在沟边03m以外，电缆沟的挖掘还必须保证电缆敷设后的弯曲半径不小于规定值，宽度、深度按设计要求开挖。Excavating:Placing warning symbols around construction location. Excavated soil should be piled and more than 0.3m is required away trenchs edge. In addition, excavation must ensure bending radius of cable is no less than regulated value. Width and depth for excavation should conform to design.敷设电缆准备工作。敷设前应整理土沟，将沟内石子或其他杂物清除，然后在沟中放置滑轮，每3m一个，转角处加放转角滑轮，保护电缆的盖板沿开挖的电缆沟分放好。同时将电缆推滚到所需位置架设好。Preparation for direct buried cable layout:Before layout, clean inner stones or other waste things up and mend trench, then place pulley into trench every 3m, and add corner pulley at the corner. Set cover plate along excavated cable trench, roll cable drum to proper location and put it onto rack.当敷设大截面和较长电缆时可采用卷扬机等机械化方法（长沙及武汉电缆附件厂有成套设备）敷设。敷设时拖拽电缆可用特制的钢丝网套套在电缆端头上。机械化敷设电缆有以下要求：While laying large cross sectional area and longer cable, following mechanization method such as hoist is available (Changsha and Wuhan cable accessory factory possess sets of equipments). Dragging cable with special making steel wire net tied at the beginning of cable. Note the following requirements when adopting mechanization method:电缆最大牵引强度（N/mm2）牵引方法牵引头钢丝网套受力部位铜芯铝芯铅套铅套塑料护套允许牵引强度704010407 Max. Draught Stress of Cable (N/mm2)Draught MethodDraught EndSteel Wire Net and SheathPressurized sectionCopper coreAluminumcoreLead SheathLeadSheathPlastic SheathAllowable stress degree704010407另外，速度不宜超过15m/min，应在牵引头或钢丝网套与牵引钢缆之间装设防捻器。 Whats more, layout speed should not surpass 15 m/min., splice-proof shall be set between draught head or steel wire net and draught cable.施放电缆时无论在任何情况下，都不能让电缆在地上拖拉，电缆到位后，可逐段将电缆提起，移去滑轮，并将电缆放在沟底，在电缆需做中间头的地方，要留有余度，在敷设过程要统一指挥，互通信息。When laying cable, no dragging cable along ground in no case. After cable reach its position, lift it step by step, remove pulley, and then put it at the bottom of trench. Leave spare length at the place of middle joint.电缆敷设完毕，请甲方及监理验收隐蔽工程，技术人员做好敷设记录。然后回填，应分层夯实，安装电缆标桩。In one word, during the course of cable layout, direct unanimously and communicate each other. After completion of cable layout, invite client and supervisor to accept concealed works. Meanwhile, technicians should finish layout recorder. Then, backfill and tamp trench learnedly. Install cable identification column.(6)、敷设电缆时，电缆允许敷设最低温度，在敷设前24h内的平均温度，以及敷设现场的温度不应低于以下规定，但温度低于以下规定时应采取措施。Temperature requirements:While laying cable, the lowest allowable layout temperature, average temperature of 24 hours prior to layout and site temperature should be no lower than following regulations. Take some measures when temperature is lower than that of regulation.电缆允许敷设最低温度（摘自GB5016892）电缆类型电缆结构允许铺设最底温度（）塑料绝缘电力电缆0控制电缆聚氯乙烯绝缘聚氯乙烯护套-10Lowe rest. temp. for allowable cable layout (GB50168-92)Type of cableStructure of cableLowe rest temp. for layout()Plastic insulated power cable0Control CablePVC insulated PVC sheath-104、安全技术措施现场工作人员必须按规定穿工作服进人现场必须戴好安全帽，高空作业系挂安全带，办理高空作业证。电缆运输装卸，脚手架搭设应有专业起重工作业指挥。电缆盘的架设应水平稳固，电缆盘引出电缆侧不应站人，防止倾倒伤人。电缆敷设时，在电缆转角的内侧不得站人，以防挤伤，或采取妥善的防护措施，在桥架上敷设电缆时应有防止电缆因一点滑落掉地而引起全段滑落的措施。滚动电缆盘时，防止电缆盘碾伤人的脚部。厂房内，管廊架上敷设电缆，所有设备孔、予留孔应加盖板，无栏杆的地方加安全网。在较封闭的场所敷设电缆，其照明通风应符合要求。防火防爆：a、敷设电缆时，作业上方不应有电气焊施焊，以免损坏电缆。b、在易燃易爆场所附近施工，应严禁吸烟和使用明火，所用的工具器材应符合安全规定的要求下面为附送毕业论文致谢词范文！不需要的可以编辑删除！谢谢！毕业论文致谢词 我的毕业论文是在韦xx老师的精心指导和大力支持下完成的，他渊博的知识开阔的视野给了我深深的启迪，论文凝聚着他的血汗，他以严谨的治学态度和敬业精神深深的感染了我对我的工作学习产生了深渊的影响，在此我向他表示衷心的谢意 这三年来感谢广西工业职业技术学院汽车工程系的老师对我专业思维及专业技能的培养，他们在学业上的心细指导为我工作和继续学习打下了良好的基础，在这里我要像诸位老师深深的鞠上一躬!特别是我的班主任吴廷川老师，虽然他不是我的专业老师，但是在这三年来，在思想以及生活上给予我鼓舞与关怀让我走出了很多失落的时候，“明师之恩，诚为过于天地，重于父母”，对吴老师的感激之情我无法用语言来表达，在此向吴老师致以最崇高的敬意和最真诚的谢意! 感谢这三年来我的朋友以及汽修0932班的四十多位同学对我的学习，生活和工作的支持和关心。三年来我们真心相待，和睦共处，不是兄弟胜是兄弟!正是一路上有你们我的求学生涯才不会感到孤独，马上就要各奔前程了，希望（，请保留此标记。）你们有好的前途，失败不要灰心，你的背后还有汽修0932班这个大家庭! 最后我要感谢我的父母，你们生我养我，纵有三世也无法回报你们，要离开你们出去工作了，我在心里默默的祝福你们平安健康，我不会让你们失望的，会好好工作回报社会的。 致谢词2 在本次论文设计过程中，感谢我的学校，给了我学习的机会，在学习中，老师从选题指导、论文框架到细节修改，都给予了细致的指导，提出了很多宝贵的意见与建议，老师以其严谨求实的治学态度、高度的敬业精神、兢兢业业、孜孜以求的工作作风和大胆创新的进取精神对我产生重要影响。他渊博的知识、开阔的视野和敏锐的思维给了我深深的启迪。这篇论文是在老师的精心指导和大力支持下才完成的 感谢所有授我以业的老师，没有这些年知识的积淀，我没有这么大的动力和信心完成这篇论文。感恩之余，诚恳地请各位老师对我的论文多加批评指正，使我及时完善论文的不足之处。 谨以此致谢最后，我要向百忙之中抽时间对本文进行审阅的各位老师表示衷心的感谢。开学自我介绍范文：首先，我想说“荣幸”，因为茫茫人海由不相识到相识实在是人生一大幸事，更希望能在三年的学习生活中能够与大家成为好同学，好朋友。其次我要说“幸运”，因为在短暂的私下接触我感觉我们班的同学都很优秀，值得我学习的地方很多，我相信我们班一定将是团结、向上、努力请保留此标记。）的班集体。最后我要说“加油”衷心地祝愿我们班的同学也包括我在内通过三年的努力学习最后都能够考入我们自己理想中的大学，为老师争光、为家长争光，更是为了我们自己未来美好生活和个人价值，加油。哦，对了，我的名字叫“*”，希望大家能记住我，因为被别人记住是一件幸福的事！）查看更多与本文高中生开学自我介绍相关的文章。精品word文档可以编辑（本页是封面）【最新资料 Word版 可自由编辑！】 精品word文档可以编辑（本页是封面）【最新资料 Word版 可自由编辑！】
