三、安全、文明技术措施(1)在桩孔开挖深度达到两米时，孔口四周设置符合规范要求的防护栏杆，防护护栏杆杆按临边防护制作，高1200mm，底部设200mm高挡脚板，防止外面弃渣滚入孔孔内。桩孔口的临边作业人员必须正确拴挂符合国家标准的安全带。护壁锁口应高出地面20-30cm防止止土石杂物坠入孔内。(2）为防止出渣掉入孔中，弃土位置距离孔口不得小于1米，弃土堆土高度不得大于1.5米，所有弃土必须及时清理出场。大块弃石破碎后提升，严禁超载提升。并并应在孔口周边设置警戒线，对不作业孔口用竹跳板进行覆盖，防防止人员误入孔内。桩孔口2m范围内严禁堆放材料、机械设备等。(3）作业人员必须配戴安全帽，绝缘手套，绝缘胶鞋，作业人员上下桩孔必须使用用专用爬梯，不得攀爬护壁或乘坐吊篮上下，上下时应系好安全绳，使用防坠器器，以防失足坠落，孔内设置应急软爬梯，并配置尼龙保险绳作应急备用，保险绳随随桩孔开挖延长。create"safeandcivilizedmodelworksfineinZhuhaicity";SectionIIqualitymanagementsysteminordertostrengthenthequalitycontrolofprojectconstructionsite,accordingtotheprojectmanagementhandbook(SecondEdition),thequalitymanagementsystemmanualandproceduresspecifiesthecontrolplan.Appliestoallconstructionqualitymanagementinconstructionworkofthisproject,thisprojectinprojectmanagementwillfullyimplementtherequirementsofthequalitymanagementsystemstandard.Thisqualitymanagementsystemistheprojectofimplementingqualityassuranceinmechanicalandelectricalinstallationengineeringconstructiononeofthebasicrequirements,relatingtotheconstructionoftheprojectstaffwill...FruitVisualshouldisfollowingstandard:flushqualifiedstandardequipmentspeed(r/min)filternetworkspecifications(accountsnumber)qualifiedstandard≥6000200Visualfilternetwork,eachsquarecentimetersrangewithinremainingofdirtrealnotthan3star<60001002,andwaterpipelinesystemdisinfection:drinkingwaterpipelinesysteminofficialdeliveredusingQianneededusedeachrosewaterinthecontaining20~mgoffreechlorineofwaterirrigationfullpipelinefordisinfection.Chlorine-containingwaterinthetubeshouldbeletstandfor24hoursormore.Afterdisinfection,rinsewithpotablewaterpiping,andsamplingbythehealthandepidemicpreventiondepartmentsafterpassinginspection,turnoffallvalvesandclosedallentrances,preventforeignbodiesfromentering.5.4.2.1drainagesystemdebuggingdebugging:debuggingsanitaryappliances,drainpumpdebugging,debugging (4)在桩孔挖至5米时，应在孔底以上3米左右处，设置防护罩，防止高处坠落物，在提升渣土时，孔内人员必须位于防护棚下避险，若遇起吊大块石或孔径较小时，孔内作业业人员应全部撤离至地面才能进行起吊。（5）桩孔内人员上下使用专用应急爬梯，不得攀爬护壁或乘提升吊具上下，并配备应急保险绳随桩开挖延长，人员上下时系好安全绳，孔口作业人员也应系挂好安全带。(6)排除桩孔内积水使用潜水泵，禁止使用内燃机放在桩孔内作为排水动力，排排水过程中桩孔内不得有人。排水作业结束，必须在切断潜水泵电源后，作业人员方可进入桩桩孔。(7)夜间禁止人工挖孔作业，井下操作人员连续工作时间不宜超过2小时，应轮换工工作。井内人员严禁吸烟、使用明火。(8）人工挖孔桩深度超过5m时先送风再下井，送风时间在15分钟以上，每天开工工前应进行有毒气体的活体检测。现场可以用活动物放入井内10～15分钟进行检测。超超过8m深的孔需设置专门设备向孔内连续通风换气，通风量不少于25L/S，并随深度的增增加送风量也应加大。（9）、挖孔桩开挖后，应设专人观察地面及建（构）筑物的变化情况，以利发生异常情况及时采取有效的处理措施。(10）施工现场的一切电源、电路的安装和拆除必须由持证电工操作。用电设备眼严格接地或接零保护且安装漏电保护器，各桩孔用电必须分闸，严禁一闸多用。孔内内电缆、电线必须采用护套等有防磨损、防潮、防断等保护措施。孔内照明应采用安安全矿灯或12V以以下的安全灯。孔中操作工应手戴工作手套，脚穿绝缘胶鞋。(11）在开工前应该检查起重工具的各个部位是否完好，防止施工过程中吊索短断裂导致的物体打击。使用的电动葫芦应安全可靠并配有自动卡紧保险装置，上班前前、下班后后均应有专人严格检查并且每天加足润滑油，保证开关灵活、准确；有保保险扣且不打死结；钢丝绳无断丝。垂直起重设备支架应牢固，应能承受一定的冲击击力不至翻倒，垂直起吊重设备必须经检验合格后，方可投入使用。（12）排水必须通过沉淀池沉淀后再排入市政排水系统中。（13）爱护机械设备，做好机械的保养和清洁工作。必须严格定期保养制度，做好操作前、操作中和操作后设备的清洁润滑、坚固、调整和防腐工作。严禁机械设备超负荷使用、带病运转和在作业运转中进行维修。create"safeandcivilizedmodelworksfineinZhuhaicity";SectionIIqualitymanagementsysteminordertostrengthenthequalitycontrolofprojectconstructionsite,accordingtotheprojectmanagementhandbook(SecondEdition),thequalitymanagementsystemmanualandproceduresspecifiesthecontrolplan.Appliestoallconstructionqualitymanagementinconstructionworkofthisproject,thisprojectinprojectmanagementwillfullyimplementtherequirementsofthequalitymanagementsystemstandard.Thisqualitymanagementsystemistheprojectofimplementingqualityassuranceinmechanicalandelectricalinstallationengineeringconstructiononeofthebasicrequirements,relatingtotheconstructionoftheprojectstaffwill...FruitVisualshouldisfollowingstandard:flushqualifiedstandardequipmentspeed(r/min)filternetworkspecifications(accountsnumber)qualifiedstandard≥6000200Visualfilternetwork,eachsquarecentimetersrangewithinremainingofdirtrealnotthan3star<60001002,andwaterpipelinesystemdisinfection:drinkingwaterpipelinesysteminofficialdeliveredusingQianneededusedeachrosewaterinthecontaining20~mgoffreechlorineofwaterirrigationfullpipelinefordisinfection.Chlorine-containingwaterinthetubeshouldbeletstandfor24hoursormore.Afterdisinfection,rinsewithpotablewaterpiping,andsamplingbythehealthandepidemicpreventiondepartmentsafterpassinginspection,turnoffallvalvesandclosedallentrances,preventforeignbodiesfromentering.5.4.2.1drainagesystemdebuggingdebugging:debuggingsanitaryappliances,drainpumpdebugging,debugging
