道路施工组织设计项目可行性研究报告⑥、当井孔混凝土面接近和进入钢筋架时，注意下列事项：混凝土面接近钢筋骨架时，使导管保持稍大的埋深，并放慢灌注速度以减少混凝土对钢筋笼的冲击力，防止钢筋笼上浮。混凝土面进入钢筋骨架4m以上，适当提开导管，保证提升导管后，钢筋骨架底部距导管下口有2m以上埋深。⑦、在接近桩顶时，采用取样盒直接取样，鉴定良好混凝土面位置，灌注结束后，良好混凝土面宜高于设计桩顶0.8～1m。（10）水下砼的配置和技术要求：采用火山灰水泥、粉煤灰水泥、普通硅酸盐水泥或硅酸盐水泥，水泥的初凝时间不宜早于2.5h，水泥强度不宜低于42.5。粗集料宜优先选用卵石，如采用碎石宜适当增加混凝土配合比的含砂率。集料的最大粒径不应大于导管内径的1/6～1/8和钢筋最小净距的1/4，同时不应大于40mm。细集料宜采用级配良好的中砂。①混凝土拌和物应有良好的和易性，在运输和灌注过程中应无明显离析、泌水现象。灌注时应保持足够的流动性，其坍落度宜为180～220mm，混凝土拌和物中宜掺用外加剂、粉煤灰等材料。②水下混凝土用钢导管灌注，导管内径为250mm。③导管使用前进行试拼、试压，检查接口连接是否严密牢固，若接口胶垫有破损，更换后使用。同时检查拼装后的垂直情况，根据桩孔的总长，确定导管的拼装长度。使用前，进行水密及承压试验，试验时的水压，大于井孔内水深至少1.3倍的压力。吊装时，导管位于井孔中央，并在灌注前进行升降试验。④attentiontoimprovingthequalityandefficiencyofdevelopmentandpaymoreattentiontosecurityandreformthepeople"slivelihood,morefocusonmaintainingsocialharmonyandstability,andpromotethedevelopmentoftownshipeconomyinabetterandfaster,createanewnormalXXdevelopmentandlayamoresolidfoundationforXXbuildawell-offsociety.Completedtasksthisyear,wemustalwayspayspecialattentiontotheprimarytaskofdevelopment.XXweakeconomicbase,lowlevelsofdevelopment,economicconstructionistheCenter,wehavetocreateconditionsforfastereconomicdevelopment,accumulatingmorewealth,betterpeople"slives.Effortshouldbemadetothisyear"seconomicgrowth,revenuegrowth,peoplehavemaintainedahighrateofincomegrowth,GDPgrowthofmorethan15percentrespectively.Alwaysgraspthefundamentalimpetusforreform.Wearenow"nosoldiersbehind"manyindicatorsrankedinthebottomofthecountyfromgettingbigger.Onlybygoingallouttohardwork,hardwork,innovation,reformdoesnotadapttoinstitutionalmechanisms,practices,itispossibletochangethefaceofXXpoor,intoawell-offsocietytogetherwithpeopleacrossthecountry.Wewanttobreaktheoldpatternsofthinking,methodsandorganizationofwork,bravelyandboldlyinto,makingfulluseofalltheadvantages,comprehensivereforms,tomakeallitsvitalityfordevelopmentimpulse,letfullplaytoallsourcesofwealthcreation.Shouldalwaysstability119

道路施工组织设计项目可行性研究报告妥善处理废方，弃土尽量避免破坏或掩埋工程周边的海域、道路及其他场地设施。重视弃土场的复垦，在弃土堆顶面绿化。(6)现有公用设施的保护对于受本工程影响或正在受影响的一切公用设施怀结构物，在本工程施工期间采取一切适当措施加以保护。靠近公用设施的开挖作业，要及时通知有关部门，并邀请有关部门代表在施工时到场。同时将上述通知与邀请的副本提交监理工程师备查。(7)泥浆排放措施本项目处于海边，故保护水质不受污染是一件意义十分重大的事。为防止钻孔中泥浆污染海域，本公司拟定制浆及泥浆循环系统，废渣及固体泥浆及时清运至泥浆场。第六章进度计划及施工总平面布置第一节施工进度计划attentiontoimprovingthequalityandefficiencyofdevelopmentandpaymoreattentiontosecurityandreformthepeople"slivelihood,morefocusonmaintainingsocialharmonyandstability,andpromotethedevelopmentoftownshipeconomyinabetterandfaster,createanewnormalXXdevelopmentandlayamoresolidfoundationforXXbuildawell-offsociety.Completedtasksthisyear,wemustalwayspayspecialattentiontotheprimarytaskofdevelopment.XXweakeconomicbase,lowlevelsofdevelopment,economicconstructionistheCenter,wehavetocreateconditionsforfastereconomicdevelopment,accumulatingmorewealth,betterpeople"slives.Effortshouldbemadetothisyear"seconomicgrowth,revenuegrowth,peoplehavemaintainedahighrateofincomegrowth,GDPgrowthofmorethan15percentrespectively.Alwaysgraspthefundamentalimpetusforreform.Wearenow"nosoldiersbehind"manyindicatorsrankedinthebottomofthecountyfromgettingbigger.Onlybygoingallouttohardwork,hardwork,innovation,reformdoesnotadapttoinstitutionalmechanisms,practices,itispossibletochangethefaceofXXpoor,intoawell-offsocietytogetherwithpeopleacrossthecountry.Wewanttobreaktheoldpatternsofthinking,methodsandorganizationofwork,bravelyandboldlyinto,makingfulluseofalltheadvantages,comprehensivereforms,tomakeallitsvitalityfordevelopmentimpulse,letfullplaytoallsourcesofwealthcreation.Shouldalwaysstability119 道路施工组织设计项目可行性研究报告测量队进场校核导线点并放样标示各项目的施工范围，公司组织项目考察队进行现场考察。据现场考察，本工程住房问题采用移动工棚解决，从集美大桥管理站引水、电，电箱设置在U型槽施工范围旁边并引线进入工棚解决员工日常用电。由于桥涵工程工期长，应先组织施工，在K1+555人行天桥施工范围内发现有大量废弃土石方、垃圾，机械进场后立即组织清理至原地面，并从鳌山路施工场地引入施工用电，K1+340人行天桥、U型槽、框架桥场地杂草丛生，与K1+555人行天桥同时清表，从U型槽旁电箱引入施工用电。引进10台桩机，分别是两座人行天桥各2台、U型槽及框架桥每个节段各1台同时施工，需要工期3个月，在此期间路基、雨水工程在工作面互不影响的情况下同时施工，路基挖填土方及借土方大约133266.7方，考虑天气影响问题及工作面问题大约8个月能完成，雨水工程结合路基施工进行，大约9个月能完成。桥涵桩基达到强度后砍桩头，组织检测单位检测桩基完整性，如果检测出桩基不及格的应及时处理，检测合格后进入上部结构建筑。两座人行天桥与U型槽及框架桥交叉作业配合同时作业能节约劳动力并节省劳动时间，U型槽72m及框架桥73m各分为3个节段，施工时从泵房先施工，再从泵房连接的节段施工往两侧节段扩展施工。先做泵房，然后K2节段底板，再做K1、K3节段底板与K2节段顶板、侧墙同时施工。人行天桥工作面有限，工序复杂，应采用班组来回作业的方法错开混凝土凝固时间，按工序进行作业。每座天桥有12根墩柱，3个承台，6个梯台，两侧梯道及主梁。按正常情况计算，本工程能在10个月内完成。施工横道图详见后附页第二节施工平面布置说明1、临时设施的布置(1)根据本标段的地理位置，结合本标段施工特点，拟设置项目经理部、加工生产场地设在工程红线外。(2)各种临时设施、生产场地、施工便道等的布置情况详见“施工总平面布置图”。2、施工通道attentiontoimprovingthequalityandefficiencyofdevelopmentandpaymoreattentiontosecurityandreformthepeople"slivelihood,morefocusonmaintainingsocialharmonyandstability,andpromotethedevelopmentoftownshipeconomyinabetterandfaster,createanewnormalXXdevelopmentandlayamoresolidfoundationforXXbuildawell-offsociety.Completedtasksthisyear,wemustalwayspayspecialattentiontotheprimarytaskofdevelopment.XXweakeconomicbase,lowlevelsofdevelopment,economicconstructionistheCenter,wehavetocreateconditionsforfastereconomicdevelopment,accumulatingmorewealth,betterpeople"slives.Effortshouldbemadetothisyear"seconomicgrowth,revenuegrowth,peoplehavemaintainedahighrateofincomegrowth,GDPgrowthofmorethan15percentrespectively.Alwaysgraspthefundamentalimpetusforreform.Wearenow"nosoldiersbehind"manyindicatorsrankedinthebottomofthecountyfromgettingbigger.Onlybygoingallouttohardwork,hardwork,innovation,reformdoesnotadapttoinstitutionalmechanisms,practices,itispossibletochangethefaceofXXpoor,intoawell-offsocietytogetherwithpeopleacrossthecountry.Wewanttobreaktheoldpatternsofthinking,methodsandorganizationofwork,bravelyandboldlyinto,makingfulluseofalltheadvantages,comprehensivereforms,tomakeallitsvitalityfordevelopmentimpulse,letfullplaytoallsourcesofwealthcreation.Shouldalwaysstability119 道路施工组织设计项目可行性研究报告利用现有的交通通道作为施工机械、材料进场的通道。在施工期间视实际的需要增设施工便道，沿路线右侧红线边铺筑施工便道，各结构物施工点引入施工便道。3、施工用水、用电按施工平面中生产及加工厂场地，生活区的需要布设电力电网和用水管网。并配备必要的加压系统和水表。施工用电、生活用电从集美大桥管理站配电房分别引至U型槽、框架桥、K0+340人行天桥、钢筋加工场及项目部。施工用水从集美大桥匝道附近的水源接入。4、项目经理部级管理人员住所采用搭设活动工棚于滨海路边空旷场地，并设置管理人员食堂、卫浴设施。项目部采取围挡封闭管理，另外，材料与机械可存放、停置于临设场地内。5、钢筋加工场设置于右匝道起点右侧边的场地上。attentiontoimprovingthequalityandefficiencyofdevelopmentandpaymoreattentiontosecurityandreformthepeople"slivelihood,morefocusonmaintainingsocialharmonyandstability,andpromotethedevelopmentoftownshipeconomyinabetterandfaster,createanewnormalXXdevelopmentandlayamoresolidfoundationforXXbuildawell-offsociety.Completedtasksthisyear,wemustalwayspayspecialattentiontotheprimarytaskofdevelopment.XXweakeconomicbase,lowlevelsofdevelopment,economicconstructionistheCenter,wehavetocreateconditionsforfastereconomicdevelopment,accumulatingmorewealth,betterpeople"slives.Effortshouldbemadetothisyear"seconomicgrowth,revenuegrowth,peoplehavemaintainedahighrateofincomegrowth,GDPgrowthofmorethan15percentrespectively.Alwaysgraspthefundamentalimpetusforreform.Wearenow"nosoldiersbehind"manyindicatorsrankedinthebottomofthecountyfromgettingbigger.Onlybygoingallouttohardwork,hardwork,innovation,reformdoesnotadapttoinstitutionalmechanisms,practices,itispossibletochangethefaceofXXpoor,intoawell-offsocietytogetherwithpeopleacrossthecountry.Wewanttobreaktheoldpatternsofthinking,methodsandorganizationofwork,bravelyandboldlyinto,makingfulluseofalltheadvantages,comprehensivereforms,tomakeallitsvitalityfordevelopmentimpulse,letfullplaytoallsourcesofwealthcreation.Shouldalwaysstability119'
