文档介绍：盖板涵施工技术交底一、施工技术方案及工艺流程(1)、施工方法及注意事项A、施工方法?基坑开挖采用全站仪放出涵洞中线及两边基础的中轴线,并移至线外作好保护桩,在根据基底标高和基础宽度用石灰线放出基坑开挖线,报请测量监理工程师检测合格后进行基坑开挖。采用挖掘机配合人工进行做业,开挖过程中及时注意边坡防护及修整,挖至基底设计标高+20cm处,改为人工开挖并找平至设计标高,并进行夯实。如有渗水发生,则在基坑下游挖一蓄水坑并进行抽水。开挖完毕,及时报请测量监理工程师检验基底标高和平面尺寸,和实验监理工程师进行基底承载力的实验。?浇筑涵台砼基础在基坑开挖整理过后,经自检、监理抽检的基底标高、平面尺寸及基底承载应力合格后,立即转入基础浇筑工作。首先按保护桩恢复中线,精确放出基础平面位置、尺寸,接着严格按尺寸、按规范支承模板,基础每4-6m设一道沉降缝,沉降缝处设竖向模板,安装完毕请监理工程师检验,合格后分层浇筑砼,并在沉降缝与沉降缝或沉降缝与墙端之间一次性连续浇筑完毕。各段浇完后,适时洒水养生,拆模板。?浇筑涵台台身及台帽涵台基础砼、台身砼的施工采用平行流水作业方式。当基础砼强度达到技术规范要求后,开始进行一段涵台的台身混凝土的浇筑。先obstacles,correctingmisunderstandings,,adheretothescientificdecision-makinganddemocraticdecision-makingdecision-,givingfullplaytosubjectiveinitiative,putanendtoimplementtheconferencemeeting,-makingmechanism,improveandimplementthedecisiontosolicittheviewsofexperts,,,mindandPartymembers,,consolidateandenhancetheparty'smasslineeducationalpracticewillpromotetheachievementofthetopicofdemocraticlife,criticismandself-criticismnormalization,along-,munication,strengtheninternalsupervision,selfSleepmaintenanceteamcollectiveimageandauthority.(three),notfromtheobjectivereality,notwiththeparty',intheimplementationofthedecisiontodeploythediscount,makechoices,engageinwork,theimplementationoftheagreement,fo
