涵洞施工技术交底样本框架涵施工技术交底单位名称：中铁四局二公司昌九第三项目队2008年03月9日工程名称里程桩号DK31+255设计文件图号施工部位基础技术交底内容：框架涵施工(1)基础施工对于有地基加固处理的涵洞,应先进行地基加固处理施工,而后进行基坑开挖。土质基坑一般采用挖掘机开挖，辅以人工清基.涵洞基坑开挖后，报请监理工程师以触探仪对基底承载力进行检测,检测合格后立即进行垫层砼施工,待垫层砼达到允许强度值后支立基础组合钢模，浇筑基础混凝土.基坑开挖时，做好截、排水设施（基坑外设挡水埂，坑内设环形排水沟、集水井，随时抽排坑中积水)，防止基坑遭水浸泡、地基条件恶化。（2）框架箱身施工框架涵采用原位分节现浇。框架涵身分两次浇筑成型:第1次浇筑底板及下梗肋以上墙身，第2次浇筑侧墙及顶板。框架模板，内外模采用组合钢模板；框架内采用满堂钢管支架,并按规定设置剪刀撑和扫地杆等。为保证混凝土面美观，交通涵框架墙身采用无内拉杆模板施工（内模利用满堂支架向两侧顶紧，外模采用双联槽钢竖向加固）。钢筋在棚内集中弯制，运至现场绑扎成型.混凝土由邻近拌和站集中供应，搅拌车运输，泵送或吊机提吊浇筑。浇筑底板前,对基础顶面进行凿毛并冲洗干净。\n为加强两次浇筑的连接和保证框架整体防水性能，水平施工缝做成“凹”字形,即在第1次浇筑时将厚度为边墙厚度1/3的方木埋入混凝土中，待混凝土终凝后取出，且在方木取出前将施工缝凿毛、冲洗干净。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,comprehensive\nreforms，tomakeallitsvitalityfordevelopmentimpulse，letfullplaytoallsourcesofwealthcreation.Shouldalwaysstability底板混凝土达到设计强度的50%后，方可搭设支架、立模、绑扎钢筋、浇筑边墙及顶板混凝土。混凝土分层浇筑，层厚以30cm为宜。混凝土浇筑时，两边侧墙对称均衡进行,侧墙混凝土通过小直径导管或串筒浇筑，插入式振动器振实，底板、顶板混凝土采用插入式和平板式振动器振实。混凝土振捣过程中，防止漏捣或过捣。当顶板混凝土强度达到设计强度后,方可拆除模板及支撑,进行变形缝、防水层及附属工程施工。(3)翼墙施工现浇翼墙内模、外模采用竹胶板、方木和钢管加固,基础施工时,按规范预埋接茬钢筋，基础与墙身接触面进行凿毛并清洗干净。因外墙面为非竖直面，应加强模板及其支撑系统的刚度、外模板采用地锚与基础连接以加强抗浮能力，采用坍落度较小的混凝土浇筑,砼浇筑速度不宜过快,以免模板爬升和出现墙面“鼓肚"现象而影响外观。(4)防水层等施工防水层施工前，将涵身上的尖凸处打磨平整，将泥土、杂物等清除干净，保持涵身表面干燥，以保证防水材料与涵身的粘结.涵身两侧分层对称回填压实，具体见“过渡段施工”交底.锥坡砌体采用挤浆法砌筑，架立样架或靠尺控制圆顺度和平整度。attentiontoimprovingthequalityandefficiencyofdevelopmentandpaymoreattentiontosecurityandreformthepeople’slivelihood，morefocusonmaintainingsocialharmonyandstability，andpromotethedevelopmentoftownshipeconomyinabetterandfaster,createanew\nnormalXXdevelopmentandlayamoresolidfoundationforXXbuildawell—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。Shouldalwaysstability施工工艺:框架涵施工工艺框图放线定位基坑开挖自检后报工程师检查浇筑基础、垫层砼试件制作钢筋制作底板钢筋绑扎\n底板立模自检后报工程师检查浇筑底板砼试件制作钢筋制作墙身及顶板钢筋绑扎、立模自检后报工程师检查浇筑墙身、顶板混凝土试件制作翼墙施工自检后报工程师审批强度检测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—offsociety\ntogetherwithpeopleacrossthecountry。Wewanttobreaktheoldpatternsofthinking，methodsandorganizationofwork，bravelyandboldlyinto,makingfulluseofalltheadvantages,comprehensivereforms，tomakeallitsvitalityfordevelopmentimpulse,letfullplaytoallsourcesofwealthcreation.
