5、.施工方案:2.1 8#暗涵K13+155K13+225,共70m长,该段暗涵太短,施工场地狭窄,根据钻探资料地质情况较好,暗涵埋深较深,我公司建议该段暗涵改为隧洞施工。方法是采用帷幕灌浆,先帷幕灌浆隧洞拱顶以上基岩,再帷幕灌浆基岩以上地表黏土,然后进行隧洞开挖,支护(开挖支护方法同后续方法)。2.2 9#暗涵K13+315K13+445共130m,资三路路基桩号为K13+315K13+395共80m和K13+395k13+445共50m分为两段,两种施工方法。2.21 降水井:在K13+395右边离隧洞轴45m打一降水井。井深低于隧洞底板高程45m,井径50cm。井打好后根据地下水流量确定安
6、装电动潜水泵进行抽水。2.22 开挖: 从K13+395K13+430段进行掘进开挖,自卸汽车运土,运至8#暗涵下一空地料场,开挖至泥岩高程,在底部两侧开挖23m3集水坑,进行地下水及隧洞掘进开挖面的地表水汇集抽排。2.23 洞口仰坡面:在仰坡面做钢筋砼横重梁式挡墙(使资三路路基回填土石方不滑动)然后再进行仰坡面支护,仰坡面支护方法先在仰面进行50mm厚C20砼素喷,素砼喷射后进行25 ,L=4m,间距1000mm锚杆和8 200200钢筋网片,钢筋网片焊接在锚杆上,再进行10cm厚C20砼进行二次喷砼,开挖深度2m一层,开挖一次进行前工序一次。2.24 固结灌浆;2.241待开挖至底板高程后
7、,拱顶开挖线以上进行固结灌浆,拱顶开挖线以上进行钻孔,孔径42mm,孔深6m,孔距为1000X1000mm梅花型布置,在采用32钢管做成灌浆管,在钢管四周钻6孔洞,间距50cm梅花布孔,将灌浆管一端锯成三块,在锤击钢管使灌浆管一端形成锥形。2.242 将制好的灌浆管击入钻孔中,再将管孔口用堵漏剂封闭管孔口。2.243再进行灌注水泥浆,水泥浆拌制加水玻璃外加剂,灌浆压力为0.098Mpa.2.25 管棚施工;2.251在洞口制作内径大于隧洞开挖断面的工字钢拱顶架,工字钢拱架采用16#工字钢。在拱架工字钢内钻45mm孔。拱架制作安装在洞口。2.252在采用42风钻杆进行钻孔,孔深3m,孔距1015
8、cm,长度为拱架圆弧段2.253孔钻好后将38钢管(外径38厚壁管)击入孔内,再进行灌注水泥浆。2.26 开挖机械: 开挖采用100型掘进机开挖,每次掘进深度6070cm.2.27 拱架安装:开始第二榀拱架安装,拱架间距50cm,再用223040cm的钢筋连接拱架,使钢拱架成一整体,钢筋与拱架焊接必须牢固。在进行第三、四榀拱架安装,第五榀拱架制作安装同第一榀,成循环作业,掘进至4.55m时,又进行第二次固结灌浆成循环。2.28 支护: 掘进到56m时,进行一次C20砼喷护,将拱架全部封闭成为钢砼支护拱圈。2.29施工方案图: 资三路与9#暗涵开挖平面布置图I-I剖面图说明:1.拱架为16#工字
9、钢 2.连接钢板和钢垫板采用10mm厚的钢板 3.灌浆管为32 4.管棚钢管为38厚壁钢管2.3 K13+395K13+445段共50m.2.31 以城镇供水管为界,先施工上游段,待隧洞施工完成后进行城镇供水管上游段施工,先将上游段进行土方开挖,再进行页岩土工格栅回填压实,碾压回填到地面高程后,再进行城镇供水管下游地表黏土开挖,在进行页岩土工格栅回填压实至地面高程。第一层压实度为80%,第二层压实度为85%,第三层压实度为90%。2.32 帷幕灌浆,先帷幕灌浆上游段,将换填部分进行帷幕灌浆,然后再进行下部基岩部分进行帷幕灌浆,下游段同上游段,帷幕灌浆后必须进行灌浆试验,灌浆试验必须达到规范要求
10、。2.33城镇供水管的保护,待上下游帷幕灌浆完成后,在从水管下游至上游进行人工开挖,长2m,挖至持力层,然后采用M10水泥沙浆砌块石保护供水管,采用边挖边衬砌方法施工。2.34 帷幕灌浆后,再从下游隧洞完成本段开挖,然后再从K13+395开始往下游衬砌施工,方法同隧洞砼施工,本方案主是解决城镇供水管。2.35 K13+440处有一小溪沟,在城镇供水管上游段回填碾压结束后,用1000mm预制砼管从隧洞轴线左岸2030m通过供水管上游段埋至高速公路水沟,再施工供水管施工。资阳市九曲河综合整治引水工程C区施工(K13+155K13+445)段暗涵变隧洞施工方案四川省场道工程有限公司2011年8月(英
