17、提交监理工程师审查。施工过程槐尖山隧道为分离式隧道，设计仰拱为65cm 厚的 C25钢筋混凝土。隧道的仰拱属于隐蔽工程，影响仰拱施工质量的因素很多，对其施工过程每一环节都必须要严格按施工规范实施，本段作为我标段隧道工程仰拱的首件工程，更对以后的仰拱施工起着样板引路的作用，因此对各种影响因素都必须有详细的考虑，施工前周密计划、合理安排，施工过程中严加控制，施工后及时总结，最终达到首件工程资料实、工程实体美、工程成品优良。1.仰拱开挖隧道仰拱采用松动爆破配合挖掘机开挖。首先测量班在隧道两侧边墙每隔5m 打一高程控制点（水泥钉标记），该点高出相应里程隧道中线路面0.5m，然后在同一里程高程控制点拉一

18、条工程线，同时找出该里程隧道中线的位置，用钢尺量出两水泥钉的距离及中线到两水泥钉的距离，然后跟设计值进行比较，来判断是否满足设计要求。利用工程线从隧道中线向两侧每隔1m 向下量隧道底面的高度，并与设计值进行比较，来判断是否满足设计要求。2.仰拱浇注为不影响机械车辆通行，仰拱、仰拱回填利用栈桥平台进行混凝土施工。主要工序施工工艺方法如下：文档编码:CH5M7J6X7C5 HG10R9M8T5T9 ZW9A4I9V5K9文档编码:CH5M7J6X7C5 HG10R9M8T5T9 ZW9A4I9V5K9文档编码:CH5M7J6X7C5 HG10R9M8T5T9 ZW9A4I9V5K9文档编码:CH5

26、不相互干扰。本隧道仰拱施工栈桥采用I40 工字钢制作。栈桥分左右两部分，每部分由四根I40 工字钢作为纵向梁，长度为12m，端部斜坡为1.5m，工字钢上铺设5mm 厚的防滑钢板。栈桥一端搭在已经浇筑好的仰拱上，另一端用用枕木支撑。栈桥要放稳、固定牢固。栈桥需移动时用挖掘机拖拽，人工配合。仰拱钢筋绑扎仰拱钢筋在洞外钢筋加工场进行加工，运至进行绑扎或焊接。钢筋加工应符合下列规定：a、钢筋在加工弯曲前应调直。b、钢筋表面的油渍、铁锈等应清除干净。c、钢筋拉直、弯钩、弯折、弯曲应采用冷加工。钢筋安装应符合下列规定：文档编码:CH5M7J6X7C5 HG10R9M8T5T9 ZW9A4I9V5K9文档编
