液压式钻孔机工序分离式施工工艺摘要：液压反循环钻孔机工序分离式施工工艺，采用液压反循环钻机钻进成孔，成孔后桩机移位到下一桩位继续施工，后续工序施工采用吊车完成，液压反循环钻机钻进能够快速有效的清除孔底钻渣，防止无用功产生。采用吊车完成成孔后续施工，使后续工序从关键工序转变为非关键工序，使得原有流程工序转换为可交叉工序，施工效率得于大大提高，工程质量满足现行规范要求，且节约了成本。关键词：液压反循环钻孔机；施工工艺；桩机；清孔；节约成本HydraulicdrillingmachineprocesstoseparatetheconstructionprocessAbstract:theconstructiontechnologyforhydraulicreversecirculationdrillingmachineprocesstoseparate,usinghydraulicreversecirculationdrillRIGSdrillinghole,holeafterpiledisplacementofthemachinetothenextlevelcontinuetoconstruction,thefollow-upprocessconstructioncranes,hydraulicreversecirculationdrillholedrillingcanquicklyandeffectivelyremovebottomslag,preventbusywork.Withthehelpofporeformingconstructionfollow-up,crane,makethetransitionfromthekeyworkingprocedurefornon-criticalprocess,makingtheoriginalprocessworkprocedure,convertcancrossconstructiontoimprovetheefficiency,theengineeringqualitymeettherequirementsofthecurrentspecification,andsavescost.Keywords:hydraulicreversecirculationdrillingmachine;Theconstructiontechnology;Thepilemachine;Holecleaning;Costsavings目录摘要______________________________________________________1Abstract___________________________________________________2第一章引言_______________________________________________5第二章施工工艺特点及适用范围_____________________________62.1工艺原理__________________________________________62.2施工工艺特点________________________________________62.3适用范围___________________________________________6第三章施工工艺流程及操作要点_____________________________73.1工艺流程__________________________________________73.2操作要点___________________________________________83.2.1施工准备______________________________________83.2.2钻孔桩定位____________________________________93.2.3埋设护筒_____________________________________93.2.4钻机就位安装__________________________________93.2.5钻机成孔_____________________________________103.2.6取样判定持力层_______________________________103.2.7成孔后桩机移机_______________________________103.2.8安放钢筋笼____________________________________103.2.9下灌注导管____________________________________113.2.10反循环清孔__________________________________113.2.11测孔底沉渣___________________________________123.2.12灌注砼______________________________________123.2.13成桩后吊车移位______________________________133.2.14泥浆的排放处理______________________________133.3劳动力组织________________________________________133.4质量控制__________________________________________143.4.1质量控制标准__________________________________143.4.2质量保证措施_________________________________143.5安全措施___________________________________________153.6环保措施___________________________________________153.6.1废油__________________________________________153.6.2废物和垃圾___________________________________153.6.3灰尘_________________________________________15第四章材料与设备_________________________________________164.1材料____________________________________________164.2设备____________________________________________16第五章社会效益及应用实例_________________________________175.1社会效益__________________________________________1...
