福建农林大学继续教育学院毕业论文（设计）题目:液压式钻孔机工序分离式施工工艺姓名:梁茂灿学号:1312910511专业:土木工程指导老师:苏忠高2015年7月31日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_____________________________________________10_____________________________________________________________113.2.10反循环清孔___________________________________________11_____________________________________________________________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___________________________________________14____________________________________________________________14________________________________________________________________153.6环保措施____________________________________________________153.6.1废油_____...
