1、工程技术交底书单位:中铁六局合福铁路安徽段站前6标项目经理部二分部主送单位路基一队日期2011.06.06工程名称DK228+208涵洞根据图号合福施(涵)-128现场领工员、技术员及班组长:现就路基一队DK228+208框架涵进行技术交底,现场施工中严格按照技术交底规范施工。一、工程概况该框架涵尺寸为4*4.7*26.95m(未计算翼墙长,翼墙为5.46m*2),中心里程DK228+208,处于地表水及地下水为CO/2侵蚀性H1等级,与线路方向斜交45°,主要用途为排洪。二、施工方案框架涵基坑采用挖掘机开
2、挖,人工配合清理并进行整平。钢筋在钢筋加工厂内集中加工,完成后运至场地内绑扎成型。涵洞模板采用组合式钢模板,倒角处可采用木模。混凝土由搅拌站集中拌制,在使用罐车运至现场,使用地泵或者泵车浇筑。涵洞施工工艺流程图如下:massestour;Increasetheintensityoftheinvestigationandmediationofdisputes,fullimplementationofthebacklogforprocessingoflettersandcallssystemofleadingc
