技术交底记录工程名称交底部位地下室顶板防水工程编号日期2012年04月09日3弹线在处理后的基层面上，按卷材的铺贴方向，弹出每幅卷材的铺贴线，保证不歪斜。上层卷材铺贴时，同样要在已铺贴的卷材上弹线。4铺贴卷材施工4.1地下室顶板防水采用热熔法施工。防水卷材铺贴前要做好基层的隐蔽检查验收工作。4.2用火焰加热进行热熔法施工时，在卷材需加热的幅宽范围内，必须加热均匀一致，要求火焰加热器的喷嘴与卷材距离适当，并保持合适的移动速度，加热至卷材的粘贴面呈光亮的黑色时方可进行粘贴。加热不够或过度加热都会影响粘贴。4.3卷材表面热熔后，立即滚铺卷材，将卷材下的空气排除，并使位置平直，不裂不扭，及时辊压。粘压应在至接缝边溢出溶化的高聚物沥青胶，使粘结严密，牢固。44.4两幅卷材短边和长边的搭接宽度均应大于等于100mm，上下两层和相邻两幅卷材的接缝应错开1/3-1/2幅宽，且两层卷材不得互相垂直铺贴。4.5铺贴平面与立面的卷材防水层时，采用外防外贴法施工，在铺平面与立面相连的卷材，应先铺贴平面，然后由下向上铺贴，并使卷材紧贴阴角，不应空鼓。4.6在立面与平面的转角处卷材的接缝应留在平面上，距立面应大于等于600mm。4.7阴阳角处应做成圆弧，在转角、阴阳角及接缝等部位应增贴1-2层同类卷材的加强层，宽度不宜小于500mm，转角两层各半。4.8在无遮盖条件下，铺贴卷材严禁在雨天、雪天、五级风及其以上时施工，当温度较低时，铺贴卷材可借助热源加热施工。4.9每一个流水段均尽可能少留接缝。4.10密封处理：为使卷材防水层增强适应变形的能力，提高防水层整体质量，在穿墙管道周围、卷材搭接缝以及收头部位，应填充增强密封膏(聚氨脂油膏)，缝隙须填嵌密实。5试水试验5.1卷材防水层施工后，应经雨后或持续淋水作蓄水检验，蓄水时间不小于24h。蓄水试验可以根据施工需要分段分片进行，但要保证该部分顶板全部进行检查，特别是对设有上反梁的顶板更不能疏忽。技术负责人交底人接受人industrialelectronics.(3)autoconfiguration,theory,maintenance,structureandprincipleofAutomotiveelectricalequipment,maintenance,carelectriccontrolsystemofstructure,principleandrepairofprofessionalknowledge.(4)thestructureandworkingprincipleofautotestanddiagnosticequipment,controlofautomobilecomprehensiveperformanceevaluationparametersandinfluencingfactors.(5)themasterthetheoryofrationaluseofthecarandrunningmaterial,businessmanagement,basictheoreticalknowledgeofmarketingandafter-salesserviceprotectionofcablescanbeupto,whilealsoprovidingafire-proof,sealed,ruggedspacecansafelyextendcabletothedestination.Channelselectionalgorithmandsubsystemleveldesignalgorithm.Aswithverticalbridge,horizontalbridgesmustalsoretainacertainamountofspaceallowancestoensurethatfutureexpansionofthesystemwithouttheneedtoinstallanewline.Sixthsection2.6.1PDScablingsystemdesign,andbuildingdesignofthecomprehensivewiringsystemaccordingtotherequirements,newDunanvalveplantmainbuilding,workshopstructure,data,voiceinthefuture;intheuniformdistribution.Mainconnection(MDF)locatedontheproductionfloorofthesecondfloorCenterroom(networkequipment),bytelephonecallsoutsidethetelephoneOfficeisresponsibleforintroducingthemainwiringinthebuilding,switchinglocationsarealsolocated 技术交底记录工程名称交底部位地下室顶板防水工程编号日期2012年04月09日5.2蓄水顶板水面要高出地下室顶板最高点20mm。必须做到无渗漏、不积水。经自检没有渗水、漏水的现象后再通知监理进行验收。如有渗水、漏水的现象应及时修复，对渗漏部分进行补强、补漏处理，重新做蓄水检验。确认无渗水、漏水的现象再通知监理进行验收。6保护层施工6.1卷材防水层施工完毕并经检查合格后，应及时做保护层。做保护层前先在卷材防水层上干铺玻纤布一层作保护隔离层，再在隔离层上浇筑40厚C20细石混凝土。6.2绑扎钢筋及浇筑混凝土时，特别注意对防水层的保护，不得损坏玻纤布隔离层和卷材防水层，否则，必须及时用卷材接缝胶粘剂补粘一块卷材修补牢固，再继续浇筑细石混凝土。7施工中质量问题及处理措施7.1空鼓：7.1.1铺贴卷材的基层潮湿、不平整、不清洁，均影响防水层与基层的粘结，基层内的水分受热蒸发，气压增大，粘结不牢的防水层内充满蒸汽与基层脱离，形成空鼓。压铺时用力不均，也可造成粘结不牢而空鼓。7.1.2卷材防水层施工时，应先检查基层，使之符合规定要求；施工时严格按照施工规范和操作规程的要求进行。对已出现空鼓的卷材防水层，可将空鼓部分的卷材剪掉，再加铺卷材按规定分层搭接，补贴密实。7.2转角处渗漏水：7.2.1卷材材破损，孔、洞、搭接处粘接不牢，搭结长度不够等，是造成防水层渗漏的几种原因，应在施工中加强检查，严格执行工艺规程，认真操作，分工序严格把关。7.2.2转角处施工不方便，常常不能保证卷材铺贴质量，转角处应做成圆弧，以利于卷材贴实。当转角处卷材防水层已产生渗漏水，则应局部都铲除防水层，分析渗漏原因、找出渗漏点，成功封堵渗漏点以后，再做增强增补处理，然后补做卷材防水层。7.3皱折：7.3.1卷材铺贴时不宜用力拉伸，但适当用力可避免卷材边缘出现皱折，短向接头可将局部片材裁齐，接头贴合后，滚压时，用力要均匀，避免将片材推出皱折。7.3.2在细部变截面部位，应裁剪合理，避免出现皱折。技术负责人交底人接受人industrialelectronics.(3)autoconfiguration,theory,maintenance,structureandprincipleofAutomotiveelectricalequipment,maintenance,carelectriccontrolsystemofstructure,principleandrepairofprofessionalknowledge.(4)thestructureandworkingprincipleofautotestanddiagnosticequipment,controlofautomobilecomprehensiveperformanceevaluationparametersandinfluencingfactors.(5)themasterthetheoryofrationaluseofthecarandrunningmaterial,businessmanagement,basictheoreticalknowledgeofmarketingandafter-salesserviceprotectionofcablescanbeupto,whilealsoprovidingafire-proof,sealed,ruggedspacecansafelyextendcabletothedestination.Channelselectionalgorithmandsubsystemleveldesignalgorithm.Aswithverticalbridge,horizontalbridgesmustalsoretainacertainamountofspaceallowancestoensurethatfutureexpansionofthesystemwithouttheneedtoinstallanewline.Sixthsection2.6.1PDScablingsystemdesign,andbuildingdesignofthecomprehensivewiringsystemaccordingtotherequirements,newDunanvalveplantmainbuilding,workshopstructure,data,voiceinthefuture;intheuniformdistribution.Mainconnection(MDF)locatedontheproductionfloorofthesecondfloorCenterroom(networkequipment),bytelephonecallsoutsidethetelephoneOfficeisresponsibleforintroducingthemainwiringinthebuilding,switchinglocationsarealsolocated 技术交底记录工程名称交底部位地下室顶板防水工程编号日期2012年04月09日7.4翘边：7.4.1接头部位清理一定要干净，如有污染，应用溶剂擦洗干净。7.4.2当卷材防水层已出现翘边等粘结不良现象时，应撕开并清理干净，根据形状将卷材剪开，再重新铺实，然后以附加卷材铺贴封严。7.5管道部位卷材粘结不牢：7.5.1主要由于细部不宜操作或施工不细致，以及管道外表面的油污、铁锈未清除干净，以致粘结不良，有皱折、张嘴或翘边现象。7.5.2为防止这种现象的产生，在铺贴卷材前，必须将管道表面上的污垢和锈迹清除干净，可视具体情况采用砂纸、钢丝刷或溶剂等清除，必要时再用高压空气将管道根部及周围基层做最后一次清理，然后再铺贴卷材防水层。8成品保护措施8.1已铺好的卷材防水层，要及时遮蔽并采取保护措施，操作人员不得穿带钉鞋作业。8.2指定成品保护负责人，明确责任范围，必要时派专人巡视施工现场。8.3在防水层施工中或防水层已完成，而保护层未完成时，是成品保护的关键时期。在此其间，禁止任何无关人员进入现场，严禁穿带铁钉、铁掌的鞋进入现场，以免扎伤防水层。防水施工人员、物料进入，必须遵守轻拿轻放的原则，严禁尖锐物体撞击防水层。8.4防水层施工完毕后，不能在防水层上开洞或钻孔安装机器设备。如不得已必须在防水层上开洞、钻孔的，应先做好记录，并安排修补。在施工过程中，如发现防水层遭到破损，应尽快组织维修。技术负责人交底人接受人industrialelectronics.(3)autoconfiguration,theory,maintenance,structureandprincipleofAutomotiveelectricalequipment,maintenance,carelectriccontrolsystemofstructure,principleandrepairofprofessionalknowledge.(4)thestructureandworkingprincipleofautotestanddiagnosticequipment,controlofautomobilecomprehensiveperformanceevaluationparametersandinfluencingfactors.(5)themasterthetheoryofrationaluseofthecarandrunningmaterial,businessmanagement,basictheoreticalknowledgeofmarketingandafter-salesserviceprotectionofcablescanbeupto,whilealsoprovidingafire-proof,sealed,ruggedspacecansafelyextendcabletothedestination.Channelselectionalgorithmandsubsystemleveldesignalgorithm.Aswithverticalbridge,horizontalbridgesmustalsoretainacertainamountofspaceallowancestoensurethatfutureexpansionofthesystemwithouttheneedtoinstallanewline.Sixthsection2.6.1PDScablingsystemdesign,andbuildingdesignofthecomprehensivewiringsystemaccordingtotherequirements,newDunanvalveplantmainbuilding,workshopstructure,data,voiceinthefuture;intheuniformdistribution.Mainconnection(MDF)locatedontheproductionfloorofthesecondfloorCenterroom(networkequipment),bytelephonecallsoutsidethetelephoneOfficeisresponsibleforintroducingthemainwiringinthebuilding,switchinglocationsarealsolocated'
